When a person suffers from myopia he or she has problems seeing objects at far distance. The effect of hyperopia is just the opposite; people have problem seeing objects which are near. Some people even suffer from both myopia and hyperopia. Previously, the only solution or cure to these problems was wearing glass spectacles. Different type of glasses was used for these problems. People suffering from both myopia and hyperopia had to bear the most. They had to wear glasses made of two types of glasses, one at the upper part and other at the lower part; differentiated by a line across the glass. Such glasses were effective, but very uncomfortable, as they were heavy and the thick frames caused much discomfort. The person had to see either through the upper part or the lower part.

It is the nature which gives us life and it is the nature which brings the disease as well. Even at that time there were epidemics, cancers and other fatal diseases. There was necessity to surgery when someone used to get injured in war or hunting. Damage to eyes was no exception to other vulnerability. They used to treat it in their own way.

Benefits of anti-reflective lens coating

Eyeglasses in various types have different benefits. Prescription eyeglasses are mainly for vision correction and sunglasses are particularly designed to offer protection from UV light. Some people simply wear eyeglasses for a stylish look. Currently eyeglasses are available in a variety of lens materials and frame materials. There are also some lens coatings such as anti-reflective coating and scratch-resistant coating and so on.

One of the common concerns from eyeglass wearers is that whether anti reflective coating is necessary. In general, the answer is yes. This coating applied on lenses can prevent excessive light from entering the eye. Without proper control of the intense light, the pupil will experience unnecessary strain.

Another advantage of anti-reflective coating is that it can address the problem of halo effect around the headlights of the opposite vehicles during night driving. This effect is quite dangerous because the vision can be distracted. Anti-reflective coating on a lens can effectively deal with this problem.

Computer users can also greatly benefit from lenses with anti-reflective coating. Regular computer users have probably experienced the bothersome glare from special parts of the PC monitor. They are forced to strain the eyes in order to get clear vision, which may lead to irritation or dry eyes. Anti-reflective coating performs well in eliminating glare. Anti-reflective coating is also believed to reduce eye pressure in dim light conditions.

In addition, eyeglasses with anti-reflective coating are particularly favored by individuals who like taking photographs. A disappointing defect of ordinary eyeglasses is that the outside images will hide the eyes while taking a photo. Anti-reflective coating can effectively block out the reflected images. This feature is very exciting and handy for photographers.

On the other hand, glasses with anti-reflective coating also need special care. While offering those benefits described above, anti-reflective lenses are easy to scratch, pick out fingerprints and become dirty. Wearers should use special cleaning tools, rather than ordinary cloth that may cause scratches.
