Types of vision problems
The National Eye Institute (NEI) states that the most common kinds of vision problems are refractive errors. This term includes:
Refraction is when the cornea and lens of the eye bend incoming light so that it’s concentrated on the retina, which is in the back of the eye. This allows you to see. A refractive error occurs when the light isn’t able to be focused on the retina, because of the shape of the eye. This can happen because of aging or changes in the shape of the eye or cornea.
Other vision problems include things like age-related macular
Degeneration, Glaucoma, and Cataracts. These can’t be treated with prescription glasses.
Nearsightedness, also called myopia, is when a person can see nearby objects clearly, but when objects are far away, they get blurry. Someone might have trouble clearly making out people on a television screen. A child might have difficulty reading the chalkboard in school.
This condition occurs if the eyeball is too long, or if the cornea is too curved. The American Optometric Association estimates that nearsightedness affects approximately 30 percent of the U.S. population.
With farsightedness or hyperopia, objects that are far away are mostly clear, while objects close by are blurry. This happens when the eyeball is too short, or the cornea is abnormally shaped. According to the NEI, farsightedness affects approximately 5 to 10 percent of the U.S. population.
In astigmatism, light doesn’t get evenly distributed onto the retina, so images can appear blurry or stretched out. However, not everyone with astigmatism has distorted vision.
This condition can happen at any age. While most people have some kind of mild astigmatism, those with more significant astigmatism might need prescription glasses to correct it.
Presbyopia was abnormally shaped. According to the NEI, farsightedness affects approximately 5 to 10 percent of the U.S. occurs in nearly everyone. It’s a typical symptom of aging. According to Penn Medicine, individuals usually start displaying symptoms of presbyopia between the ages of 38 and 42.
As we age, the eye isn’t as flexible as it used to be. When it’s not able to flex as well as it did before, focus on nearby objects becomes impaired. This is why many people need bifocals or reading prescription glasses as they grow older.
The bottom line
If you’re experiencing any of these symptoms, see an eye doctor as soon as possible. Even if you’re not having any symptoms, it’s a good idea to get regular eye exams with dilation to ensure that you’re seeing clearly and to keep tabs on your eye health.
Only an eye doctor will be able to do a comprehensive eye exam to see if you’d benefit from wearing prescription glasses. If the results indicate that you need prescription glasses, your doctor can speak with you about the kind of lenses that would be best for your condition, as well as any other treatment.
