Using Corrective Eye Lenses
Individuals who suffer from cataracts need to look into eyes lenses that can help restore their vision. Cataracts are opaque areas on the eye lens that inhibit the light from entering the cornea. This lack of light makes it difficult for people with cataracts to see properly. To correct this, there are many different types of eye lenses available. Individuals will find them in either soft or hard forms, and most start out fairly small but expand with time to fit any type of eye. An optometrist must fit the proper lens to not delay restoring one’s vision after they start wearing them.
Catoptrics Eye Lenses
The most common type of corrective lenses is known as catoptrics. These lenses are designed to correct farsightedness, nearsightedness, and astigmatism. What occurs is that light rays pass through the lens at various angles, which eventually focus on a focal point. The focal point enables individuals to see objects clearly at various distances away, for example, for reading or looking at objects close up. Keeping these lenses clean is important since they sit directly on the eye. It takes some time to adjust to wearing them, but with regular use, it becomes easier over time until one gets accustomed to the sensation of using corrective big eyeglasses.
