Question: I wear no-line bi-focal glasses!.Are there contacts made to correct this condition!? Thanks!.!?
Answers:
Yes, but they work on a different optical principle!.
(except for some rarely used gas-permeable rigid lenses)

You would need trials with a contact lens expert to see which, if any, of the methods worked for you!.

All the methods require a person with good vision in both eyes!. They are not really suitable for anyone with a lazy eye etc!.

1) Monovision: fitting one eye for distance and one for near!.
When it works people tend to love it, but most can't tolerate it, due to how their binocular vision is set up!. Cheap, and easy to try!. Astigmatism can usually be corrected!.

2) A range of bifocal and varifocal contacts, which carry both near and Rx's in all directions of gaze, unlike bifocal/svarifocals, where the reading portion is at the bottom!.
This gives great flexibility, but that comes at some loss of contrast levels*, and a fair chance of glare and flare with night vision!.
There is only a limited rage of correction for astigmatism available!.

Again, those who find a brand that suits them, love them!. Others tend find them too compromising of their vision!.

The success rate depends a lot on what is being hoped for, and what compromises will be accepted!. Nothing delivers the perfect flexible vision of a teenager!.


*blacks are not so black, whites not so white!. In good lighting this may matter little but in poorer light, or looking at greyish print, the quality of vision may be markedly affected!.
