Important Tips for Wearing Contact Lenses

Contact lenses are used to correct vision but they can be used for cosmetic or therapeutic  reasons as well. There are many reasons for what people choose to wear contact lenses. The most motivating factors are aesthetics and cosmetics for the people  who would like to change the appearance of their eyes or would like to avoid from glasses.
If we compare with glasses, lenses give better peripheral vision, and they don’t collect moisture as snow, rain, sweat or condensation. Lenses are ideal for outdoor activities, unlike spectacles. One of their best sides is that a contact lens wearer can wear as well as sunglasses or other eye wear of their choice. Also, keratoconus and aniseikonia are better corrected by contact lenses than with glasses.

They can be classified in different ways. For their function contact lenses are:
1. Corrective;
2. Other types of vision correction (for the people with color deficiencies);
3. Cosmetic;

By their material contact lenses are:
1. Rigid, made of glass which weren't comfortable enough to gain widespread popularity;
2. Soft, with oxygen permeability;
3. Hybrid, with rigid centre and soft skirt.

For their wear schedule, there are:
1. Daily wear lenses;
2. Extended wear lenses.

The use of contact lenses is safe as long as they are used correctly. The risk of possible damage  of the eye arises when lenses are used too long or when people sleep with lenses that are not designed for extended wear.
One of the most well-spread complications is that the lens is a barrier to oxygen. Mishandling can cause problems and complications, as well. Removal of contact lenses must be done very carefully otherwise it can result in injury to the eye or damage to the eye. Taking a nap with contact lenses may result in vision problems. In case of serious effects, the only option is surgery.
You should keep in mind, that before touching lenses, hands must be clean. A dirt free and clean container always must be stored for contact lenses to avoid side effects and risks.
