There are many types of vision problems; not all are treatable with glasses or contact lenses. We will discuss 5 common vision issues in this blog post.
You can take several corrective measures if you have any of these vision problems.
Read on to learn more about these vision problems and how you can correct them.
Astigmatism is a type of vision problem brought about by an irregularity in the shape of your cornea. If you have astigmatism, your cornea may be shaped more like a football than a basketball. Consequently, this can cause light to bend improperly as it enters your eye, resulting in blurred or distorted vision.
Presbyopia is a type of vision problem that occurs as you age. As you get older, the lens of your eye becomes less flexible, which makes it harder for your eye to focus on close objects. The result can cause blurred vision when reading or doing other close work.
Myopia, or nearsightedness, is a vision problem that occurs when your eye is too long or your cornea is too curved. In turn, this causes light to bend improperly as it enters your eye, which results in blurred vision when looking at distant objects.
Hyperopia, or farsightedness, is a type of refractive error where the eye focusing system causes distant objects to appear sharper and clearer than up close. But near objects are usually blurry. Hyperopia occurs when the eyeball is too short, or the cornea has too slight curvature. Thus, this prevents light from adequately reflecting onto the retina, creating an out-of-focus image.
The primary symptoms of hyperopia occur in childhood. The list includes:
- Starting school with a report of normal vision that gradually decreases
- Making a lot of mistakes on homework
- Refusing to do homework
- Slowed reading speed and comprehension
- Having trouble reading close up (such as getting lines on the page confused)
- Squinting or rubbing eyes more frequently during time spent reading
Strabismus is a condition that causes the eyes to point in different directions. It affects proper binocular vision and can lead to amblyopia, otherwise known as lazy eye. Strabismus can involve any age group and often develops in early infancy when babies are particularly sensitive to advances in three-dimensional vision skills.
While genes play a role in its development, strabismus has also occurred with premature birth and low birth weight. Common symptoms include:
- Double vision or blurred images
- Seeing only part of an image
- Headaches or eye strain
- Poor depth perception
