First of all, I must say that I am 53 years old, type II diabetic with good control and a smoker. The problems I am experiencing may be age related. However, reassurance would be great. Three days ago, I woke up with the lack of ability to fully focus my field of vision, When I look up or down everything seems to swim and am unable to fully judge distance. While looking straight ahead , there seems to be no problem. It just so happens that it was time for my yearly eye exam and had the exam that very day. I spoke with the Dr. (optometrist) and she did a thorough exam and could not give a definitive answer. My vision prescription had not changed and all the other tests she performed, I was able to pass. She stated that most likely it was eye strain from having spent a couple of days prior to extensive computer work. One day later another symptom appeared in my left eye. While rubbing my eyes I noticed my left eye experiencing pain when I applied pressure. I would like to mention here that the "swimming" and lack of ability to focus in all range of vision , is reminiscent of the day I awoke and I suddenly had to begin to wear reading glasses. It would great to know that what I am experiencing is an age progression and possibly time for a "tri" focal. Any information would be greatly appreciated as this has become a great source of worry and concern.
