Common Vision Problems

What does it really mean to be "nearsighted" or "farsighted," and what are the other common vision problems that affect people of all ages? At Pycraft Family Eye Care, refraction assessments are part of our comprehensive eye exam. At this point, you may be wondering what is a "refractive error”, so allow us to explain. 

Defining the Four Common Types of Vision Issues

Myopia (nearsightedness) and hyperopia (farsightedness) are the most common types of refractive errors. 

Hyperopia, commonly referred to as farsightedness, is a type of refractive error where nearby objects appear hazy or blurry. You likely don't think about it, but when you squint to look at a nearby object, what you are doing is actually manipulating the cornea -- the "lens" of the eye.

Myopia is the medical term for nearsightedness. With this condition, an individual's cornea is misshaped in such a way that makes faraway objects appear blurry. This is one of the most common types of refractive errors, but is treatable through the use of contact lenses or eyeglasses. 

Astigmatisms are caused by a defect in the cornea, the lens of the eye, which results in objects appearing distorted or blurry. The blurriness is a result of the light waves not quite meeting at the back of the eye, at the retina. Instead of a clear image, the brain tries to pull some useful information from what it is "seeing" by blurring or averaging the finer details.

Presbyopia is a form of farsightedness, but it is one that is associated with aging. This disorder is caused by the lens of the eye losing some of its elasticit, which makes objects appear blurry when viewed up close.
