How does Night Vision Work?

The eyes form images from the light which gets into the eyes from our surroundings. The parts of the eye which assist in seeing in the darkness, as explained by the optometrist in Port Louis are:

Pupil – The pupil is the aperture of the eye, just like a camera. It allows small amounts of light during brightness and vice versa. It adjusts accordingly to help the vision.

Rods and Cones – The rod and cone cells are used to create the balance of colours and darkness within the eye. This balance helps in giving the coloured image.

Photopigments – Chemicals which are sensitive to light are held in the rods and cones of the eye. These cells convert the light energy into electrical energy which our brains can interpret.

Taking care of the eyes, both under bright and dark conditions is very important to ascertain a healthy vision in the long run.

How are COVID – 19 and Vision Co – Related?

Doctors, even before the pandemic hit humanity, always warned us to not touch our eyes or nose or mouth with our hands. Covid – 19 gets transmitted through water droplets which are released in the air. Upon being released by an infected person, it remains suspended in the air and when it comes in contact with any inlet of a human body, the virus enters the system.

Eyes are also one of the inlets and thus using bare hands to touch the mouth, nose and even the eyes is not suggested. Professionals at the best optical shop in Mauritius are directing the patrons on a regular basis to follow the hygiene protocols thoroughly and are doing the same at their end too.
