Hello,

Welcome to Just Answer

RGP lenses are made up of PMMA which is hard and not possible to be made into liquid form. But newer lenses made of silicone hydrogels are being tried which are very soft. As of now there are no liquid contact lenses possible.

Silicone hydrogels cannot be changed into liquid form. Further details you can get from this link- http://en.wikipedia.org/wiki/Polyacrylamide

Can a polymer start off as a liquid form and harden as it touches the eye to form a type of contact lense around the cornea?
Expert:  Dr. A.S. Desai replied 6 years ago.
Since the newer lenses are still under experimentation, it could be possible to make liquid lenses which harden on contact with the eye in the future.

At present there is no such material available or present in the market( as we are practising ophthalmologists we get to know about products which are available and not possible to know about those under research). You will get more infomartion about such research work on the net.

Your concept is good and wish you the best with your invention.

Thanks and best wishes
