Varifocal Glasses for the Highest Possible Vision Comfort

Generally, when human beings develop a vision disorder

, it is either one of myopia or hyperopia. Myopic patients find it difficult to view objects located at a distance while the individuals who suffer from hyperopia cannot clearly view the objects located nearby. This problem can be issued by single focal prescription glasses which have only one power in their lenses to correct the eyesight. But with increasing age many people also acquire presbyopia which entails dual power in the lenses. Bifocal glasses can be used in such cases but the drastic change in the two powers of the lenses can irritate many users.

Advancement in science and the technology of manufacturing glasses made it possible to address this issue and varifocal glasses were introduced. Varifocal glasses have a gradually increasing power on their lenses, with the top part of the lenses having the lowest power and the maximum power at the bottom most part. When one has to look at objects at the distance, the upper part of the lenses is used. For purposes like reading or looking at close-by objects, one just has to look through the lower part. The intermediate part of the lenses can be used to view objects which are located at an average distance. With the increasing use of computer, the intermediate part of the lenses has proved hugely beneficial.

Varifocal Glasses offer their users many other advantages. In difficult situations like driving down a road and reading the map at the same time, varifocal glasses can save you the trouble of constantly swapping your glasses to look at a distance and then to look closely at the map. In the above mentioned situation, swapping is not only impossible, but dangerous too. These varifocal glasses also have various coatings on their lenses like UV, anti-scratch and anti-reflective coatings. The UV coating, as the name suggests, protects you from the ultra-violet rays of the sun while the anti-reflective coating reduces the glare of the incoming light leading to better eyesight.

Varifocal glasses are available in all the three frame designs fully rimmed, semi rimmed and rimless. Each one of them have their own set of advantages and drawbacks, and a proper knowledge of these will help you to choose the design which will suit to your taste the most. To choose the cheapest options of varifocal glasses, you should browse the collections at the online stores, as the rates charged at these online stores are almost half of the prices at the retail stores.
