Vision Problems

A concise guide to some of the most common vision problems treated at Thomas Vision Clinic

There are many different types of vision problems that could be affecting your eyesight. But, for the purposes of this guide, we will be focusing on four of the most common causes of impaired vision. These, along with many other vision impairments, are treated with care and precision by Drs. Mark & Cherri Cowan, O.D. at Thomas Vision Clinic.

Astigmatism

astigmatism01Astigmatism is an uneven or irregular curvature of the cornea or lens, which results in blurred or distorted vision. Other symptoms of astigmatism include the need to squint, eye strain from squinting, headaches and eye fatigue.

Hyperopia (Farsightedness)

hyperopia01Farsightedness, medically known as hyperopia, refers to vision that is good at a distance but not at close range. Farsightedness occurs when the eyeball is shorter than normal, as measured from front to back, or when the cornea has too little curvature. This reduces the distance between the cornea and retina, causing light to converge behind the retina, rather than on it.

Myopia (Nearsightedness)

myopia01Nearsightedness, medically known as myopia, refers to vision that is good at close range but not at a distance. It generally occurs because the eyeball is too “long” as measured from front to back.

Presbyopia (Aging Eyes)

presbyopia01Aging eyes, medically known as presbyopia, is a condition in which the lens of the eye gradually loses its flexibility, making it harder to focus clearly on close objects such as printed words. Distance vision, on the other hand, is usually not affected.

Unfortunately, presbyopia is an inevitable part of aging and cannot be prevented by diet, lifestyle or visual habits. However, it is treatable with several types of corrective lenses, including progressives, bifocals and trifocals, single-vision reading glasses, multifocal contact lenses and monovision therapy.
