The present invention relates to a contact lens, and particularly to a contact lens build in with a layer of air which allows light to refract properly and help us to see clearly under water.
It is very difficult for us to see underwater,
The human eye is designed to focus light onto the retina, but when you are underwater, the light is refracted and the image is not formed on the retina but somewhere behind it making things look differently,
Refraction of the light normally takes place when the light rays travel from the thinner air into the denser cornea. However, water has a similar density to the cornea, so light doesn't refract properly That's why when we're underwater, everything looks distorted or blurry.
Normally, light passes through the cornea, which begins focusing the light. It is then focused on the lens and onto the retinas, The images are then transmitted up the optic nerve to the visual center of the brain.
To see underwater, today divers wear flat diving masks to see underwater which uncomfortably tied up on the forehead, our vision is blurry and foggy when moisture builds up inside the mask.
The present invention—Have a layer of hydrogel glass built in on the front of the contact lenses keeping a slight air gap between the lens's curved surface, creating a pocket of air between the wearer's eye and the surrounding water, which allows light to refract properly and help us to see clearly under water.
The preferred embodiments of the described invention relate particularly to an apparatus of a contact lens has been built with a layer of hydrogel glass in the front with a slight air gap between allowing a pocket of air to be formed between the wearer's eye and the surrounding water which, in turn, allows light to refract properly and help us to see clearly under water.
