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.
