Beware of online eye exams...

We love technology but be weary of websites online offering glasses and contact lens prescriptions. These sites offer "eye exams" but yet there is no actual examination. They perform a refraction. Having a refraction online is no substitute for an eye exam.

TEST IT TUESDAY: We tried out the web site It offers online eye exams from your home or office. No more going to the eye doctor. But, does it work?
