Varifocal Lens
Varifocal Glasses & Spectacles for Presbyopia Correction
Varifocal glasses are a special form of multifocal spectacles. Varifocal glasses are also known as the progressive glasses, graduated glasses and no-lines bifocals. It is called by the name ‘varifocal' because there are different powers at different levels of the lens. At the top of the lens, the power is minimum, which gradually increases in the middle level and finally, the bottom part of the lens has the maximum power.
Varifocal glasses are the most effective tool to correct presbyopia. It is a very common eye disorder for people who reach the age of 40. The near vision of the affected person slowly deteriorates. Reading and looking at nearby objects become a concern.
Before varifocal glasses, presbyopia was used to be corrected by the single-vision reading glasses. Though they did a decent job in presbyopia correcting, they were particularly ineffective when the person had a vision disorder other than presbyopia. These single vision glasses were unable to deal with nearsightedness and farsightedness. This necessity led to the growth of bifocal and trifocal reading glasses. As the lenses of these glasses have more than one focal point or lens power, they were called multifocal reading glasses.
But these lenses have lines running through them and dividing them into two or three areas, which make these prescription glasses unattractive options.
Commercially, varifocal glasses are quite popular because of the absence of any line on the lens. The greatest advantage of varifocal glasses is the ability to look at objects at varying distances with just a slight tilt of head. As the different levels have different powers, the top part can be used to view objects at a distance, the middle one at the objects at an intermediate distance and the bottom part while working on the nearby objects, like reading a book. They also avoid the discontinuities like image-jumps which occur in the visual fields created by bifocal and trifocal glasses.
With the increasing use of varifocal glasses, various manufacturers are constructing stylish varifocal glasses. Even designer brands are designing spectacles with thicker rims which make them perfect for varifocal lenses. The easiest way to buy varifocal glasses now-a-days is to find them online. These online stores not only offer the widest range at your fingertips but you can also take your time to go through them. When compared to the prices charged at retail stores, these online stores priced their products at surprisingly low rates.
