Why Polarized?
Polarized sunglass lenses block polarized light, which is concentrated light reflected in a horizontal direction causing what we know as glare. Glare is stronger than regular ambient light that’s very uncomfortable and can be very dangerous to your eyes.
All Zeal Optics sunglass lenses are polarized and eliminate 99.9% of glare, block 100% of harmful UV rays and 95% of HEV light (harmful blue light). This helps prevent long term damage to your eyes due to exposure to harmful HEV and UV light. By eliminating glare, you are also eliminating eye fatigue and sensitivity that comes with it so you can stay outside longer doing the activities you love.
Not All Polarized Sunglasses Are Created Equal!
A low-quality polarized lens can filter too much or too little light, leading to a distorted picture. Sunglasses that do not provide UV protection can actually cause more damage than going without because they shade the eye, causing the pupil to dilate and allow in more harmful UV rays.
Glare is Problematic...
What is the underlying reason we wear sunglasses? Ultimately, it’s comfort, to block that nasty glare, whether we buy for fashion, function, or protection. Glare confuses color and is problematic. In fact, 26% of daytime car crashes are attributed to glare and driving is rated as the #1 use for sunglasses. In fact, 39% of glare-related accidents occur between 6 and 9 am, during rush hour. More specifically, the 15 minutes after sunrise and before sunset are the most dangerous times for road glare. According to the American and Canadian Automobile Association, and eye care professionals all over the world, the best way to handle glare is to “invest in polarized sunglasses.”
Myopia, commonly known as near-sightedness, is a prevalent eye condition affecting many individuals, especially children. Orthokeratology (Ortho-K) emerges as a leading non-surgical solution for myopia control in kids' vision. This innovative technique utilizes specially designed Ortho-K lenses to gently reshape the cornea during sleep, offering effective myopia management.
Ortho-K lenses play a crucial role in addressing myopia progression by applying targeted pressure on the central cornea, leading to its flattening. This not only corrects vision but also contributes to myopia control in children. Research suggests that Ortho-K lens wear at night can significantly slow down the progression of myopia, making it a promising option for parents concerned about their kids' vision health.
Despite the proven benefits of Ortho-K, the alignment of the treatment zone with the pupil center can impact visual outcomes. Some studies explore the effectiveness of centered versus decentered Ortho-K lens wear in delaying myopia progression in kids.
In a retrospective study involving 217 subjects undergoing Ortho-K treatment for over 12 months, the impact of centered and decentered Ortho-K lens wear on myopia control was assessed. Surprisingly, the results revealed no significant differences in axial length changes, a key indicator of myopia progression, among subjects with varying degrees of Ortho-K lens decentration.
Age emerged as a notable factor influencing axial length elongation, with an average decrease in axial length change per year. This finding underscores the importance of considering age when evaluating the effectiveness of myopia control strategies in children.
In conclusion, Ortho-K, or orthokeratology, stands out as a promising avenue for myopia control in kids' vision. This study suggests that while lens decentration is a common occurrence, it may not significantly impact myopia control outcomes in children undergoing Ortho-K treatment. For parents seeking effective myopia management solutions for their kids, Ortho-K remains a compelling option worth exploring.

Polarized Technology
Lenshop UVO polarised sun lenses eliminate blinding reflected glare, to offer you greater visual comfort, excellent clarity of vision, better reaction time and improved performance in whatever you do.
Glare can be reflected off many surfaces such as water, glass, grass and metallic surfaces.
Prolonged exposure to glare and sunlight can lead to visual fatigue and discomfort. Glare can also contribute to an increased risk of accidents while driving due to slower reaction time.
Ideal for all activities under the sun, regardless of the environment, situation or season.
ELIMINATES BLINDING GLARE
Waves of light travel in many directions. When light waves reflect off of flat surfaces; such as roads, water or ice, it becomes polarised, or is reflected horizontally. This is known as blinding glare, which can be uncomfortable for our eyes. Lenshop UVO technology allows only vertical light through the lens and therefore eliminate blinding glare for optimal visual comfort and enhanced colour perception.
IDEAL FOR DRIVING
Driving is an essential mode of transport for most of us. Lenshop UVO polarized technology enhances daytime driving experience by eliminating blinding glare produced by reflections on wet road surfaces, dashboards and other cars, allowing you to better anticipate changes and hazards on the road.

Instructions for ordering prescription eyewear online
By simply following the below steps you can easily order your prescription eyewear from Lenshop!
1. Step 1 select the frame you are interested in. By selecting the option "Add with lenses" you can add the lenses to your frame.
2. Step 2 asks you to select the type of lenses you require. For example if you have a problem with distance, near or both (these lenses are commonly referred to as multifocal or progressive lenses). Alternatively you may want to add new lenses without prescription.
3. Step 3 asks you to upload your prescription manually, otherwise you can "upload" a photo of it. Please make sure that you include your pupillary distance (PD). You can learn more here regarding this measurement.
4. Step 4 asks you to select the most appropriate coating based on your needs. For example, if you prefer your lenses to be as transparent as possible, whilst reducing fluorescent reflections from the front surface of the lenses (excellent in all conditions, particularly night driving). Alternatively you may spend multiple hours using digital devices and would prefer a coating that filters the harmful parts of the blue light spectrum, which in turn reduces eye strain and fatigue. You may want them to change colour and darken outdoors for comfort and protection from sunlight (photochromic lenses).
5. Step 5 requires you to choose your preferred lens manufacturer. We cooperate with all major optical companies.
6. Step 6 allows you to refine your options from the company you have chosen. Options vary depending on the quality of the coating as well as the refractive index of the lenses.

Therapeutic Contact Lenses: A "tool" to restore eye health
Contact lenses for many people are a means of correcting their vision, whether they have a distance or near vision problem or a combination of both. Few people know that contact lenses can also be used for therapeutic purposes. Therapeutic lenses are a safe and effective treatment for a wide range of eye disorders or conditions.
What are therapeutic lenses?
Therapeutic lenses are essentially no different from common contact lenses that correct any vision problem the user has. But there are specific characteristics that are required for a contact lens to be called therapeutic. As they act as "protective bandages", therapeutic contact lenses are usually made of materials with high oxygen permeability and specific thicknesses and diameters and can be used for daily or prolonged use. They are used for healing the eye, relieving eye pain and protecting the ocular surface.
Their main purpose is to restore the integrity of the cornea* while at the same time minimizing the patients' symptoms. The fitting of these therapeutic lenses, whether temporary or as part of a long-term treatment plan, should be considered a medical treatment or procedure and not a lens itself. Finally, therapeutic contact lenses protect the cornea from environmental conditions and deal with the abrasive effects of the patient's own eyelids. Wearing these lenses can help restore corneal tissue, manage pain, and preserve vision.
*The cornea is a transparent membrane and anatomically covers 1/6 of the entire eye and is located in the center of the eye
In which cases can they be used?
There are many situations in which contact lenses can be used as a therapeutic mean:
● Protection, strengthening and support of the corneal epithelium: They are used as supportive means after surgical operations, refractive surgery operations, corneal transplants while providing relief and immediate healing of the eye. For these conditions, therapeutic contact lenses should be considered a temporary measure until corneal healing is achieved.
● Pain Relief: They are used as a pain reliever in various pathological and traumatic conditions involving the cornea such as bullous keratopathy and filamentous keratitis that can cause severe pain to patients. A patient's quality of life can be significantly improved with the use of therapeutic lenses.
● Improvement of any abnormal surface of the cornea: They provide protection to the surface of the cornea, protecting it from the forces of the eyelids as well as diseases of the eyelids such as trichosis or ectropion where with the movements of the eyelids they can cause abrasions to the cornea. Their use can expedite the healing of the cornea and reduce the risk of infection.
● Corneal healing: They can provide complete healing of the cornea. They have the possibility of being applied in the form of a "pressure bandage" in order to strengthen and prevent the cornea from tearing after injury or even after chemical burns. They can temporarily stop wound drainage after cataract surgery.
● Medicate: They can be used successfully to treat an eye condition with the combined use of contact lenses and medication. Such eye conditions can be neurotrophic keratitis, chemical burns and after corneal transplantation.
But what do therapeutic contact lenses offer?
The use of therapeutic lenses in pathological eye conditions helps them to heal faster but at the same time significantly reduces pain. Τhey also prevent the eyelids from interfering with the normal healing of the corneal cells since with every blink the eyelids essentially "scratch" the cornea. In addition to this mechanical protection, therapeutic lenses help to keep the eyes hydrated thereby preventing serious dry eye conditions.
Menicon's premiO is a therapeutic contact lens with healing purposes and has superiority both in quality and in the time of accelerating the healing of the epithelium compared to other lenses. It is a product of sophisticated polymerization of hydrophilic monomers (Menisilk), providing high permeability to oxygen, excellent hydrophilicity, resistance to fats and tear proteins and impressive sensitivity due to the sophisticated processing of its surfaces. This particular contact lens has FDA approved for 6 nights of continuous use (even while sleeping). It is mainly used after refractive surgery but also in cornea transplants.
Menicon's Bandage lens has an advantage over other corresponding lenses of other companies due to its high hydrophilicity and the large diameters (from 16 to 22mm). It is indicated in a number of eye complications or diseases such as entropion, trichosis, drooping eyelids, bullous keratopathy, corneal abrasion, ulcer or swelling, keratoconjunctivitis where a larger contact lens diameter is required to completely cover the healing point.
Postoperative rehabilitation and follow-up
Therapeutic contact lenses have managed to successfully deal with all the problems that can arise post-operatively while offering safety and immediate healing. The use of therapeutic lenses requires special attention, excellent expertise and knowledge, cooperation between optician/optometrist and ophthalmologist in order to assess the patient's needs and choose the most suitable contact lens design.
The contact lens will be fitted by an optometrist or ophthalmologist and will be worn continuously until the next appointment. Most people only need the contact lens for a short period of time and so do not need to handle the lens themselves. Occasionally the therapeutic contact lens may need to be fitted on a longer term basis. If this is true, an optometrist can guide the user on the correct procedure for insertion, removal and maintenance.
It is critical to carry out frequent follow-ups of patients with therapeutic contact lenses. One reason is that a therapeutic lens fit, by design, shows less movement than a traditional soft lens fit. In addition, it is important for the ophthalmologist to be vigilant in detecting signs of microbial keratitis. The success of application and avoidance of complications is inextricably linked to the patient's full compliance with the instructions for using the lenses as well as their frequent post-operative follow-up.
For more information about the use of therapeutic contact lenses, ask the specialized staff at one of our company's stores.
How can we improve the back to school experience for every student across the board?
Good and functional vision requires visual acuity, visual skills and the connection to the visual pathways in the brain to "work" together in harmony.
When this is not the case, even a child who sees 6/6 (perfect visual acuity), may experience difficulties reading, writing and processing visual information, Thus:
• 80% of all information that children receive derives visually.
• 75-90% of learning in a classroom is done visually.
• 80% of children who have difficulty reading have visual impairments that can be treated if necessary with special optometric exercise programs.
Therefore, three areas need to be checked so that parents can be sure that their child's vision will not be an obstacle to their school progress:
1. To be examined by an ophthalmologist that the student's visual system is healthy and that he does not have any refractive problem such as myopia, high hypermetropia, astigmatism.
2. To be checked by a qualified ophthalmologist or optometrist that ocular health, convergence, focus and eye movements are working normally
3. To be checked by a qualified optometrist that the collection of visual information, visual perception, visual memory, visual processing speed and hand-eye coordination are properly developed.
Can we train our eyes to reduce or avoid Myopia as we age?
The simple answer is no, however there are ways of slowing the degree of myopia. Fortunately, science and technology have made leaps and bounds in recent years. For example, a child with myopia of -4.50 dioptres who refuses or is uncomfortable to wear glasses may be suitable for orthokeratology lenses. Commonly referred to as Ortho-K lenses, these are custom made rigid contact lenses deigned to be worn overnight to gently reshape the surface of the cornea, Allowing the wearer to not need contacts or glasses during the day. Upon taking the lenses out in the morning the child can see clearly and cope with any of his activities without having to wear his glasses, while his myopia will remain stagnant or may even recede. It is a treatment that is based on the same principle as braces for the teeth or the guardian for the spine. In fact, in many advanced countries, such as Japan, New Zealand and Australia, the cost of this method is often covered by the health system in cases where patients are considered legally blind (Spheric powers above -5,00 and cylindric powers above -3,00)
Is innovation the biggest trend in the magical world of glasses?
It sure is. In addition to the orthokeratology we mentioned, there are many more innovations that protect vision or make our everyday life easier. Examples include:
• Glasses that absorb blue light, to which children are constantly exposed by using electronic devices.
• Photochromic glasses that act as dimmers for our eyes. That is, as long as we are exposed to UV radiation (such as solar), the glasses will darken as much as is necessary to protect our eyes.
• Polarized glasses that, in addition to the sun's rays, filter a certain amount of light by cutting reflections, so that we can see without the sun blinding us, which is why we see colors more clearly with polarized glasses.
• Very important for children is the anti-scratch technology, which ensures that the lenses of the glasses are hardened and are not easily scratched like ordinary lenses. They are 6 to 10 times more difficult to etch, so you need to ask for this kind of coating. It is good to ask for a hydrophobic coating (so that water does not stick to the lens), a lipophobic coating (for fingers) and an antistatic coating (so that it does not hold dust) along with hardening. Remember that all quality lenses come with an authenticity card that certifies all of the above and is essentially the identity of the lenses.
• There are also photochromic contact lenses that darken in strong sunlight, so that the user's eyes are not tired of the bright light even when he is not wearing sunglasses.
Your local optician or optometrist will be able to provide you with the best solutions to cater to your main concerns.
Are glasses an issue of inclusion in the school community and how can this be improved to the maximum?
It is important that the glasses serve the needs of the children, but it is equally important that they do like them. Let them try until they find what expresses them and don't pressure them into their choice. The optician will recommend a frame depending on the child's condition, so that the frame helps the child with his peripheral vision, but not so large that it weighs him down or falls. Fortunately, there are now many companies, designs and colors of frames as well as cute accessories such as special cases, cloths and cords that make this process more enticing to the wearer. So, along with school supplies, bags and cases, put your children's eyeglass accessories on your list.
What are the SOS of the new year?
1. Visit the ophthalmologist (initially) or your local optometrist if there are signs of reading difficulties, refusal to study, slow copying, attention difficulties, etc.
2. Make an appointment at an optical store so you can have available the time your child needs.
3. Make sure that the optical store you choose has certified Optician-Optometrist staff and not simply salesmen only, in order to guide you scientifically based on your child's needs.
4. If the child is in pre-adolescence or adolescence and wants to start with contact lenses, select an Optical store which will be done after studying the trained knowledge and understanding of how to correctly fit and check the ocular health of your childs eyes and who can confidently instruct the insurtion, removal and hygeine maintenance required for all contact lenses.
5. Provide the child with a second pair of glasses, lens cleaner, anti-fog and cloth in their bag.
6. Never give pressure to children to get what parents want. Choose what your kids want to wear, because only then will they wear the glasses even when you're not looking.
Do not hesitate to contact us in order to learn more about all the discussed matters listed above.
You have found the perfect pair of eyeglasses online, but you can't order them because you don't know your pupillary distance, a very important prescription parameter. With the following instructions you can easily measure the distance from home.
What is pupillary distance?
The distance between the two pupils from center to center and it is measured in millimeters.
If you want to order a pair of glasses that are only for near distance and you are over 40 years old use the pupillary distance for near vision, which is easily found if you remove 3mm from the pupillary distance for long vision.
Why is the pupillary distance important in the making of glasses?
Each lens that you place in a pair of eyeglasses has an optical center that is defined by the distance between the two pupils of the eyes.
Calculation of pupillary distance
Your prescription may write your pupillary distance, if not, ask a friend for help or use a mirror to calculate it.
- What you will need: ruler & mirror
- Stand 20cm in front of the mirror
- With your face straight, hold the ruler along your eyebrows
- Close your right eye and place the zero in the center of your left pupil
- Looking straight, close the left eye and open the right
- The millimeters that coincide with the center of the pupil of your right eye is your pupillary distance.
Some additional information
- Measure the pupillary distance 3-4 times to reduce the chance of error
- The range of an adult's pupillary distance ranges from 54mm to 74mm
- The range of a child's pupillary distance ranges from 43mm to 53mm
Using a friend to measure the pupillary distance
If a friend is measuring your pupillary distance, keep both eyes open and hand the ruler to them to place it along your eyebrows and place the zero in the center of one pupil. The pupillary distance is found by reading the millimeters that are above the center of the other pupil of the eye.
Tips!
- Keep your eyes still as much as possible
- Don't look at the person measuring you
- Focus on an object above his/her head about 3-6 m away
- Make sure during the process that your eyes are at the same height
With the pupillary distance and the correct prescription, you can purchase eyeglasses through a valid online optical store Lenshop.eu, saving time and money.
Barça and Etnia Barcelona launch an exlusive sunglasses collection
The FC Barcelona and Etnia capsule collection being presented on Wednesday comprises seven designs that commemorate both brands’ origins, taking inspiration from the Catalan club’s historic moments
Barça and Etnia Barcelona present a unique collection of luxurious and bespoke sunglasses, which are both inspired by the city of Barcelona and a tribute to the brands’ roots. Presented on Wednesday, the new and exclusive capsule collection of seven different models celebrate their origins, with the designs acknowledging the Catalan club’s heritage and the Mediterranean spirit of an innovative and visionary city with an international outlook. With the launch of this capsule collection, Barça is clearly committing to reach out to new target audiences with links to the world of art and culture.
As FC Barcelona is a reference for many artists, and Etnia Barcelona has links to art while remaining true to their DNA, both brands have come together in a contemporary collection. The Dutch painter, Pascal Möhlmann, known for paying homage to the Flemish painter, Van Dyck, and Virgil Abloh, a US fashion designer, also collaborated. Defined as "new beauty" with a 'punk’ attitude, their style is reflected in the campaign’s imagery and the glasses’ packaging, representing the feeling and strength generated by the connection between the Club and its fans around the world.
The collection comprises seven pairs of sunglasses, each with a design containing characteristic elements from the Club and its history. This exclusive capsule collection has two drops that share the same identity and merge a vintage style with contemporary trends. The seven models derived from the collaboration are as follows:
1899 Gold. - Limited edition sunglasses with a deconstructed and recreated Barça crest in the form of an exclusive oversize frame made from top quality materials, like natural black acetate, HD polarized mineral lenses, and finishes in 24 karat gold. Only 1899 units of this unique piece will be available, a number that gives the sunglasses their name, while also referring to the year the Club was founded.
The Colors of our History. – An exclusive collection that celebrates some moments from FC Barcelona’s history. London 1992, Paris 2006, Rome 2009, London 2011, Berlin 2015 and Gothenburg 2021 provide the names for the six sunglasses in this vintage style capsule collection, which commemorates moments from FC Barcelona’s history down the years and the cities in which the men’s and women’s football first teams won the Club’s six Champions League titles. The design is inspired by the colors of the jerseys worn by the Barça players during each of those six victories, and they are manufactured from top quality materials with HD polarized mineral lenses.
The Barça and Etnia Barcelona capsule collection is manufactured using high quality materials, such as Mazzucchelli acetate and Barberini color HD mineral lenses that give them a unique look in terms of color and quality, in line with the Barcelona brand’s regular range of sun wear collections.
The sunglasses come with an iconic recyclable vegan leather case - black with the Barça shield for the 1899 Gold model, and brown for The Colors of our History drop - complementing the capsule collection’s vintage style. The packaging includes the campaign’s image, created by Pascal Möhlmann, which is also in customized suede, and comes with a postcard containing the illustration and a limited edition card.
