Can you replace the lens in reading glasses with the lens from your normal glasses?

Generally reading glass frames are flimsy and of poor quality and do not stand up to the wear and tear of every day use. Add to this the fact that prescription lenses are ground to fit specific frames (no one size fits all) and would have to be ground specially to fit the old frames and the cost becomes prohibitive. If you want "cheap" frames buy them at a yard sale, but bear in mind these may be worn, twisted and out of alignments and still have the problems of grinding the new lenses to fit them.

The power of a lens depends on the differences in the refractive indices of the environment and the lens material. A glass lens immersed in water will loose power (a positive lens will focus at a greater distance). (This is for normal glass with refractive index greater than water - there could be glasses with refractive index less than water in which case the lens would gain power)

Be aware that you can end up with a pair of reading glasses with a flawed lens if you are buying cheap reading glasses online so try to use a reputable vender with a guaranteed return policy.

The rays are diffracted toward the center of the lens. This is the principal used in reading and magnifying glasses.

Why is it that in a pair of bifocal glasses the converging lens at the bottom and the diverging lens at the top?
It is a split screen usually the bottom part is cut as the (close up) lens the normal or larger part of the lens is normal- depending on whether one needs primarily distance or close-up correction, or for reading. the bottom lens group is usually secondary, not the main task. Franklin invented bifocal eyeglasses. He also devised the lightning rod, Franklin stove and *Long arm, lever device often used in grocery stores.
What type of eyeglasses will a patient need after cataract surgery?
