Types of prescription eyewear lens

Single vision lenses

Your eyes might require vision improvement only for distance, only for reading purpose, or even for both. If you require correction only for distance vision, then you probably only want single vision lenses. With single vision lenses, you could look through all areas of the lens and it is visible clearly. If you desire vision improvement only for reading and in case you do not have astigmatism, then you could even purchase non-prescription reading glasses. If you do have astigmatism, you should go for prescription reading glasses. In either case, these are only considered single vision lenses.

Progressive lenses

Progressive lenses are sometimes as well recognizedas no-line bifocals, which are in fact trifocal lenses without the visible lines. Progressive lenses were urbanized as many people required the convenience of not having to change their prescription glasses for reading purpose, but they did not like other people to see the visible line. Progressive lenses do have an additional benefit however, which is that you sense a soft transition when you move your eyes from far away objects to close up objects. With a lined bifocal, the transition among viewing areas could even be somewhat uncomfortable.

Multifocal lenses

If you require vision adjustment for both distance and for reading purpose, then you could use two pairs of glasses, and swap depending on what you require to see. Or, you could even choose multifocal lenses (bifocal lenses, trifocal lenses, or progressive lenses). Many people find it not convenient to swap every now and then to another pair in order to read something.

Multifocal lenses divide the lens, so that part of the lens is kept for reading and another part of the lens is kept for distance vision. Bifocal (two areas) and trifocal (three areas) lenses have visible lines, which separate the diverse areas of the lens.

Prescription reading glasses

Non-prescription reading glasses just enlarge objects that are close to us, like the letters in a book. Your eye doctor could only decide the magnification power, which is most excellent for you, or you could figure it out by yourself through test and error. A doctor's prescription is not sometime necessary in order to choose a reading lens. Drugstore reading glasses are just eyeglasses frames with enlarging lenses pre-loaded in a range of powers with stock lens powers. It is typically less costly to buy reading eyeglasses this way, but stock lens powers hardly ever offer an optimal vision correction. For best results, reading lenses with magnification customized to your requirements could be installed in any pair of eyeglasses frames.
