Understanding the Importance of Vision Correction

When people aren't seeing properly, it can cause all sorts of issues besides simply having blurry vision.

For example, school-age children sometimes experience symptoms like those of ADHD when they have vision problems that aren't being treated. They also can have trouble learning in school, since about 80 percent of learning occurs through the eyes.

In elderly individuals, having untreated vision problems could actually increase the risk of various types of dementia. Although the link between dementia and vision problems needs to be further studied, the theory is that the vision issues are making it so elderly individuals don't participate in the types of activities that make dementia less likely, including physical activity and reading.

There are a few alternatives for vision correction, and they are mentioned below.

Glasses or Contacts

The most common type of vision correction is through the use of glasses or contacts. However, these are temporary solutions that only work while a person is actually wearing these corrective devices.

Contact lenses can be more convenient, as they don't fog up in the weather, don't get in the way during sports and give you a wider field of vision than glasses. However, glasses are better if you spend a lot of time working on the computer or if you tend to get dry eyes. Not properly caring for contact lenses could also make eye infections more likely.

Glasses tend to be cheaper than contacts, though, and don't require you to stick your finger in your eye. They also protect your eyes somewhat from dust and debris on windy days. Many people have both contacts and glasses and alternate between them as needed depending on the situation.

A Permanent Solution

Surgery is the only way to achieve permanent vision correction. One of the more common alternatives is LASIK, but other alternatives that can be better in certain specific situations include intraocular lens implants and refractive lens exchange. The first is better in cases of unusually shaped corneas or extreme nearsightedness, while the second is a good alternative for those with cataracts or farsightedness. In general, laser eye surgery candidates should have had a stable prescription for at least a year, not play contact sports, not be pregnant or breastfeeding and be at least 18 years old.

Certain diseases and medications make it harder for the body to heal, making laser eye surgery more risky, including diabetes and rheumatoid arthritis. Thin corneas, large pupils and dry eyes can also make someone a poor candidate for the surgery.

The results of the surgery vary, with about 50 percent of people being able to totally give up wearing glasses, about 14 percent still needing to wear glasses all the time and many of the remaining people needing to wear glasses for seeing up close. Side effects, such as dry eyes, halos, blurry vision and light sensitivity, are also common in many patients and can last for more than 6 months after the surgery.
