What is the difference between contact lens materials?
Contact lens materials are mainly divided into two types, namely hydrogel and silicon hydrogel , each has its advantages:
Hydrogel is the most used contact lens, and most people buy it. The advantage is soft, easy to wear and lower price. Most contact lenses use this material. Hydrogel has the characteristics of high water content, generally ranging from 55-69%. The higher the water content, the lens is relatively soft, and the air permeability is higher than that of the low-moisture lens. No matter transparent, astigmatism Con, Color Con and progressive contact lenses are made of this material.
The main brands are Acuvue Moist , Acuvue Define , Bausch & Lomb Soflens 1day , BioMedics 1 day and our flagship product Perfect eyes 1day, etc.
Silicone hydrogel is a relatively new material. The advantage is that it has ultra-high oxygen permeability and can be worn for a longer time. However, with the advancement of lens technology and technology, silicone hydrogel lenses have made great progress. Miacare is also the firstbrand tolaunch Color Con , a silicone hydrogel . There are 6 colors to choose from, which can make your eyes healthier whiledressingup.
The benefit is that the silicon hydrogel directly introduces oxygen in the air through the silicon, and does not need to transmit oxygen through high moisture like hydrogels, reducing the chance of dry eyes. Furthermore, the oxygen permeability of the lens has been greatly improved, and the wearing time can be prolonged.
The main brands are Acuvue Trueye (discontinued), Acuvue Oasys and Clariti 1day, etc.
In addition to the above two materials, Dailies Total 1 Day uses exclusive technology to manufacture hydrogel lenses, combining hydrogel and silicon hydrogel.
Except for the contact lenses of different materials, which will affect the wearing comfort, should the moisture content of the contact lenses be sorted? Check out another article on how to choose contact lenses- compare the wearing time and moisture content
