Vision Problems

There are countless diseases, medical conditions, medications, and types of trauma that will affect one’s vision. This guide will focus on some of the most common causes of impaired vision and the treatments offered at Cargo Eye Care of Las Colinas to help patients restore some or all of their visual abilities.

Many people do not realize that almost everyone has at least some level of astigmatism, and it is generally believed to be a hereditary issue. Astigmatism is a condition in which the cornea has an irregular or uneven curvature.

For most patients, an astigmatism will result in slightly impaired vision, the need to squint one or both eyes, and headaches from squinting. After being diagnosed with minor astigmatism, a patient will typically be able to correct the condition with contact lenses or eyeglasses. In moderate to severe cases, an astigmatism may be treatable with LASIK surgery.

Hyperopia (Farsightedness)

Referred to in the field of medicine as hyperopia, farsightedness is the condition in which a patient has good or perfect vision at a distance, but cannot see as well up close. The two most common causes of farsightedness are corneas that are not curved enough or eyeballs which are too short when measured from front to back. These two conditions will cause the light to converge behind the retina, which can lead to vision problems.

There are a number of treatment options offered at Cargo Eye Care of Las Colinas suggested for this condition. For most mild cases, patients will either require no treatment or will benefit from contacts or eyeglasses. If you have moderate to severe farsightedness, you may be a candidate for LASIK surgery or photorefractive keratotomy (PRK).

Myopia (Nearsightedness)

Myopia is the opposite of hyperopia and takes place when the patient can see well at close range but their vision blurs at longer distances. Nearsightedness typically occurs when patients have a longer eyeball when measured from front to back.

The team at Cargo Eye Care can test you for nearsightedness during any basic checkup and will often suggest eyeglasses or contacts for mild to moderate cases. Severe myopia may require acrylic corneal implants, LASIK, radial keratotomy (RK) and photorefractive keratotomy (PRK).

Presbyopia (Aging Eyes)

As we begin to age, the lenses within our eyes will lose their flexibility which can make it difficult to focus on nearby items such as books and computer screens. Presbyopia does not generally affect seeing at a distance and is a perfectly natural part of aging.

This condition cannot be prevented with lifestyle changes, diet or visual habits. Luckily, it is often quite treatable with options such as contact lenses, bifocals, trifocals, monovision therapy, progressive eyeglasses, and single-vision reading glasses.
