Special eyeglasses used after cataract surgery or for presbyopia

This should be an article about presbyopia and the need of multiple pair of glasses or progressive eyeglasses after cataract surgery. Some people may not tolerate the progressive eyeglasses. In the last couple of years there were a few tentatives to put on alternative to the progressive eyeglasses on the market: - emPower eyeware from PixelView - electronic eyeglasses that had fantastic promisses. They had some technical difficulties and some financial trouble and declared bankruptcy before they could roll out their second generation of products - SuperFocus - liquid based, adjustable eyeglasses. They closed their business - AdLensFocuss - liquid based adjustable eyeglasses - seems to be better then SuperFocus, but the eyeglasses are almost twice as heavy as regular glasses and very expensive.

Another promise cames from DeepOptics that's working some electronic eyeware (Omnifocals)
