do need varifocal sunglasses
Varifocal glasses are a very practical and cost effective solution to the problem of presbyopia. Presbyopia is when the lens at the back of the eye can no longer change shape to bring close objects into focus.This is something that the vast majority of adults will suffer from when they reach the age of 40+.urrently on average, only around 0.7% of our customers return their varifocal glasses, mainly due to non-tolerance issues. The fact remains that the vast majority of people adapt to these lenses with ease and usually within the first few days of wearing them.
