I've been using Focus Dailies by Cibavision for a few years now. i order them online and save a fortune. they're good for people who are prone to eye problems, and are so thin you can't feel them in your eyes.
I think most optometrists stock sample lenses - ask for a few types and test them out, that way you don't waste any money if they're not the right ones. The daily lenses are great, I highly recommend them.
The best brand I have found (in Australia) is Acuvue Oasys with Hydraclear Plus. I tried quite a selection prior to settling with this brand. I have astigmatism in one of my eyes and suffer from dry eye making my eyes extremely sensitive. These apparently allow more oxygen to diffuse through the lens pores and into the eye. They also have a UV blocking film. My optometrist kept giving me sample brands to try until we hit jackpot with this one. I've been wearing the Acuvue Oasys for a couple of years now.
