I have had eye problems since the age of two. I had eye surgery and have been wearing eyeglasses ever since. I started wearing contact lenses since the age of twelve and gas permables since the age of 17. I went and saw Dr. Gifford last fall and it was the most in-depth eye exams I have had to date. My gas permabales he perscribed have been the best fitting to date. I highly recommend Dr. Gifford who anyone who has special vision needs.
