Question: Who would use varifocal glasses and why!? !?
Could someone describe to me why would somebody have to wear varifocal lenses!? I have tried looking up the meaning in the wikipedia, but not much info - how does it differ from bifocal for example!? No sarky comments please - just a simple informative answer would do, thank you!. Www@Answer-Health@Com


Answers:
Bifocals have a line across the centre of the lense and you either look over it or under it, whichever lense you need!. Varifocals do not have a line and are gently graduated to enable you to just look down to read!.Www@Answer-Health@Com

when people get older , or because they have bad eyesight sometimes they become short sighted and long sighted at the same time!. The lil semicircle bit is for looking at things closely, while the rest is for looking at things normally or far awayWww@Answer-Health@Com
