The disadvantages of Bifocal Glasses

[red eyeglass frames]

Compared with the multifocal, bifocal is a short-sight correction lens that has a separate long-sight correction lens contained in a small area in the lower half of a lens. The disadvantages of this though are that to use your long-sight correction you have to take care to look using a small lens area at the bottom of the lens. These glasses also often look strange.
