Varifocal lenses are also called progressive lenses. They have different prescription powers on their surface and work by changing focus from top to bottom. The topmost part of the lens gives you a better distant vision while the bottom part caters to your near vision needs. The middle part is meant for intermediate distances when working on a computer. Use varifocal lenses for work, reading a book or looking at things far away. Get your varifocals from Specscart at discounted prices and get better visual performance across all distances.
