But this quality also engenders some drawbacks. When you look around you into the distance, all you can catch sight of is a stretch of blurry image. Half -frame, however, overcomes this shortcoming by means of separating the whole lens into two parts respectively capable of fulfilling needs of both far and near vision. In this way do bifocal reading glasses resemble half-frame a great deal. Bifocal reading glasses feature far vision power in the upper part of lens and the bottom part is covered with near vision power which is usually used for reading close -up materials.
