people to wear contact lenses and glasses while others do not? Depending on factor such as their family history and environmental causes, the way that people's eyes work and appear can vary from one individual to another. This pertains to eye color, visual accuracy, and eye mechanism. Unfortunately, in some cases, the eyes of some people do not work as they should. This is where contact lenses or eyeglasses come into play. These visual tools help people achieve clarity with regard to their eyesight.
How Eyes Work?Before anything else, it's important to understand how the eyes work and why they sometimes do not function or perform as they should. The eyeball is comprised of the cornea, clear tissue, the iris, the pupil, the lens, and the retina. Clear tissue and the retina are responsible for helping the eye focus while the pupil allows light into the eyes.
When all parts of the eye are working as they should, a person will not experience any vision-related problems. This means that your eye is capturing each image that it sees, sending the picture back to your brain, and it is interpreted as it should be. On the other hand, if your retina does not work as sharply as it should, the image appears fuzzy to your brain. This is where the refractive problem comes in. Thankfully, glasses and contact lenses help to bend the light rays correctly so that your vision problem is correct.
