The Varifocal Glasses Give an Outstanding Solution
When compared to the single – vision and bifocal glasses, varifocal glasses are comparatively new. Known as progressive glasses, these varifocal glasses are also known by other monikers as well, like graduated glasses and no-lines bifocals. As the name ‘varifocal’ suggests, these glasses comprise of lenses which have graduated powers at gradual levels. The power is at its lowest at the top of the lenses, then keeps increasing as we move towards the middle of the lenses and then reaches its maximum level at the bottom part.
Earlier, before the invention of varifocal glasses, there was only one option for patients suffering from both myopia and hyperopia. The bifocal glasses used to have lenses which were made of two different lenses, resulting in a final lens which was thick in structure. Not only did it increase the weight of the prescription glasses but they used to look nerdy and unfashionable. Obviously, users were unable to wear these frames for long durations without feeling a strain and pain. This disadvantage of being cumbersome was corrected by the varifocal glasses. Since the lenses have different powers, there was no need to put on different lenses together, thereby reducing the overall weight of the pair. And as the middle section of the lenses can be used to view objects situated at an average distance, it proved to be a wonderful option for those who have to sit in front of a computer for long time.
These varifocal glasses are available in all the three frame structures – fully rimmed, semi rimless and rimless glasses, though it is always preferred to have a thick rim around the lenses. As the varifocal lenses are generally more expensive than other lenses, a rim around them ensures longevity. But if you want to reduce the weight of the frame then rimless options are the way to go. But your decision to select the frame eventually depends on the prescription. It is a wise decision to go to your doctor and get an updated prescription and then the lens thickness will depend on it.
In case you are looking for maximum options to choose from, then the online stores dealing with prescription glasses are your best bet. These online stores have dedicated pages to varifocal glasses and display a range of choices, covering a wide spectrum of colours and designs. These stores give you the luxury to go through them at your own pace and the prices charged are way lower than the retail ones.
