There are a number of contacts made for dry eyes. Your best bet would be to find an eye care provider (probably an optometrist) who specializes in fitting people with dry eyes. I've found the 1-Day Acuvue Moist lens to be especially comfortable. Other possibilities are the Acuvue Oasys, Extreme H20, and some by Proclear. The new 1-Day Acuvue TruEye is supposed to be available in the USA sometime soon. It's a 1-day, very thin, disposable, silicone hydrogel lens currently used in the UK and Ireland.
I advise patients with dry eyes and Sjorgren's not to wear contacts because of the risk of infection, ulceration, scarring and blood vessels growing over cornea (neovascularization). There are some discussion on contacts for dry eyes in previous discussions that you can access with the search and archvies feature.
