I have been a patient of Dr. John Chrisagis at Tempe Eyecare since 1988. I find him to be extremely knowledgeable and thorough. I have a couple of conditions he is watchful of, one called cupping, the other is a family history of glaucoma. Originally I wore contacts, however, now I only use glasses. In addition to being very professional and personable, he is so honest about not trying to sell me something I don't need. For example, the last several visits my prescription has changed very little. Rather than trying to sell me glasses I don't really need, he advised that drug store readers would be sufficient, and that I really don't need bifocals as my distance vision is almost 20-20--it has actually improved with age!
