Do they make monovision glasses?

Question

Like instead of bifocals can I have one lens for reading and one for distance? Would that work?

Answer 1

I have done this successfully before for people who wear monovision contact lenses or people who have large differences in prescription between the eyes. It is certainly possible, but many people will not adapt to it, it is harder to get used to than in contact lenses.

Answer 2

If you mean on the same pair, no, they do not do that.  They can give you one pair for reading and one for distance or do the bifocals which would be much easier.

Answer 3

For most people, unlike when you do this with contacts, it does not work very well. It has to do with vetex distances, or how far away the lense is from your eye. Another thing is that there would be prism imballance when looking down into the lense to read having such a difference between the two powers, where in a contact lens situation the lens in on the eye, and there is no imbalance as the lens does move with your eye as it converges to read. Without a background in basic optics you would not understand it, and with a background in basic optics youw ould not ask, you would know, so it is hard to explain. It just does not work well and the math just does not work out. I hope I did not confuse you more!
