I have needed glasses for short sight (about -6) since the age of 8 & decided to treat myself to better vision for my 50th birthday. Because of my age, Prof. Gartry recommended mono vision, where one eye was corrected for distance and the other made slightly short sighted to help me read. I can now thread a needle without glasses and can read small print. I don’t need correction for distance vision in my daily life. It’s a fantastic transformation, all delivered professionally and with a smile. Thank you, Prof. Gartry!
