Common Causes of Vision Problems
Vision problems could occur naturally in people whose eyes did not develop correctly at birth or in people who experienced some type of trauma to the eye later in life. Some vision problems arise due to the degeneration of tissue linked to aging. The key to resolving any vision problem is in understanding the underlying cause.
Common Vision Problems
The most common problems people have with their vision, arise because the lens of the eye is not able to focus images correctly. This incorrect focus could create either nearsighted or farsighted vision. This problem generally occurs in childhood, when it can be detected and corrected through the use of prescription lenses.
In recent decades, some people have experienced blurry vision due to continued use of computers. The eye has several muscles which work with the lens to help it focus on both near and far objects. People who look at a close object for prolonged periods of time will begin to experience blurry vision and headaches. This is because the muscles are not working the way they should. People who work with computers can alleviate their headaches and blurry vision by looking away from the screen every few minutes to focus on something farther away.
Vision Problems with Aging
As people get older their tissues begin to break down, which could lead to impaired vision. The most common problems associated with aging are macular degeneration, cataracts and glaucoma. Macular degeneration creates a blurry central portion of an image. This can impact the person’s ability to drive, read or perform daily tasks. Cataracts also lead to impaired vision by clouding the images seen by the eye. Cataracts also affect colors, often making it difficult to discern one color from another.
When it comes to senior health, glaucoma is the vision problem that causes the most concern. This condition damages the optic nerve, which connects the eye to the brain. There are several different conditions associated with glaucoma, each leading to severe deterioration, loss of vision and possible blindness.
Diabetes in senior adults could also affect their vision. Diabetic retinopathy is a complication of senior diabetes where the small blood vessels of the retina become damaged. It is important for seniors who have been diagnosed with diabetes to have regular eye exams to catch the onset of complications before they become too severe.
