Vision becomes distorted when the surface of the cornea has an uneven curvature. Sometimes it is the eye’s lens that is irregularly shaped. This type of irregularity causes light to focus on more than one spot in the back of the eye, causing blurred vision.
Over time, the eye’s lens gradually loses its elasticity and its ability to change shape to see close objects. Bifocals or reading glasses are the traditional prescriptions for remedying this presbyopic loss of accommodation, but recent technology makes it possible to exchange the inflexible lens for one designed to compensate for the changes in the eye and improve functional vision at all distances.
Dry eye is a general term used to describe a group of conditions that result from a dry cornea. Symptoms of dry eye include redness and irritation. This condition can be caused by the normal aging process, medications, exposure to air pollution, or other environmental factors, and it sometimes appears in conjunction with other diseases. People who wear contact lenses are more likely to experience dry eye.
Eye redness is a key sign of dry eye. Other symptoms include itchiness or grittiness, burning or stinging in the eye, or sensitivity to light. People who have dry eye often complain that it feels like there’s something in the eye that causes discomfort, or remark that their eyes tire easily when they read or watch television. These activities require concentration, which decreases the frequency of blinking and gives the tear film that keeps the eye moist more time to evaporate.
Contact lens intolerance can also be a symptom of dry eye. Often, a person with mild to moderate dry eye may not experience symptoms of dry eye until they begin wearing contact lenses, which can upset the delicate balance of tear film production and distribution.
Diagnosis of dry eye begins with an eye exam. It is important to rule out the possibility that another condition, such as an infection, is causing your symptoms. After diagnosis, your eye doctor will suggest one or more of several treatments now available to treat dry eye.
