Cataracts are a leading cause of vision issues for people over 40 and are one of the main causes of blindness. A cataract is a clouding of the eye, specifically in the eye’s lens behind the pupil, caused by proteins clumping together. There are different kinds of cataracts, and they can have different causes. Aging or other medical conditions can contribute to the development of cataracts in your eyes.
Cataracts can start small and develop slowly. It may not even be noticeable at first, or you may notice a slight blur to your vision. You may only notice symptoms when looking at bright lights. Cataracts can continue to worsen, and you may only feel the effects once it is well developed.
Glaucoma describes eye disorders that involve damage to the optic nerve, which sends visual signals from your eye to your brain. This loss of nerve tissue can result in loss of vision.
Primary open-angle glaucoma is one of the most common disorders. It results from an increased pressure inside the eye, which can cause damage to the optic nerve. A damaged nerve can lead to vision loss or even blindness. This pressure can build slowly and be difficult to detect in everyday life. It may start by affecting only your peripheral vision.

Computer Vision is a relatively new term within the optometry field and refers to eye problems associated with the prolonged use of computers and electronics that use a digital screen. Although it can be temporary, there are times when computer vision can strain the eyes to a degree that permanently affects your vision as well. An existing eye condition can worsen as the eyes try to focus and adjust to a computer screen and precautions should be taken if you spend long hours in front of a computer screen. Some people with an astigmatism will feel completely normal until they get in front of a computer and the condition seems to come back into play. Just as some people use glasses for driving at night there are glasses specifically designed for use with a computer.
