I am going to put forth a question. My eyes are becoming tired in the afternoons, is it possible that my prescription glasses are no longer the correct prescription for my eyes? I have older pairs of glasses that maybe I should try. I do have an appointment on April 11th for getting tear duct plugs to hopefully help my eyes. I am now hoping that I can get my doctor to check my vision and scan my eyes to check my macular degeneration. Even with my dark sunglasses I could see much better details while I am out walking the forest trails that I have been walking for about 7 years. I was seeing things I haven't noticed before, it could be that I was actually looking more closely now. The MD chart still have straight lines and no curves or ghost. In general my perception is that my vision is improving, but could that be wishful thinking? I don't believe so. As I now read my Kindle using font size 4 or 5 instead of 7 or 8. 4 when my eyes are not tired 5 when my eyes are tired. As for as my dry eyes go I am still using Refresh Tears, and Refresh gel during the day and I use Refresh PM orinment when I go to bed. My eyes seem to stay less dry, and more than likely due to the high pollen my eyes water some while out walking the trail. I am actually trying to analyze my data, which is just my perception.
