How Contact Lenses Work

Today, more and more people are using contact lenses varying from teens and adults. Contact lenses are
now more preferred for the fact that they are easy to use and more convenient than glasses and does
not change people’s appearance the way glasses do. However, they work in different ways depending
the type of contact lenses.

Cosmetic or decorative contact lenses are type of contact lenses that change the appearance of the eye.
These lenses come in a variety of colors and design. There are also some contacts that make the eye
look confusing and scary in appearance which are commonly used in horror movies.

Contact lenses also work to correct and or improve vision. Many people suffering from eye ailments
have mismatched refraction of the eye and the length of the eye causing to a refraction error. Contact
lenses work to neutralize this mismatch and correct the focusing of the light into the retina. People
suffering from Myopia or nearsightedness focus light rays too early within their eye and form a focus
point in front of the retina instead of directly onto it. Contact lenses correct this by diverging light rays,
which reduce the eye's focusing power. This moves the eye's focus point backward, onto the retina
where it belongs. People who are suffering from Hyperopia or farsightedness do not have adequate
focusing power and light rays fail to form a focus point by the time they reach the retina. Contact lenses
correct this by converging light rays, which increase the eye's focusing power. This moves the eye's focus
point forward, onto the retina.

There are also contact lenses that work to treat and manage non-refractive disorders of the eye.
Bandage contact lenses protect an injured or damaged eye that have been ablated, have corneal
abrasion or erosion from rubbing or constant blinking thus allowing it to heal and reduce discomfort.

In short, contact lenses work depending on what people’s eyes need. They could work to change the
appearance of the eye. They could also work to correct or improve vision for people who are suffering
from eye ailments. Contact lenses also work to treat and heal eyes that had been damaged or injured.
