I am nearly 67. My eyesight started to change for the worse over 20 years ago. Since then, I have tried painting front sights, using green fiber optic front sights (they help), prescription glasses and scopes and dot sights. Scopes and dot sights turn lithe and finely balanced handguns into top heavy 2x4's. And holsters for scoped handguns - forget it. No more fast work.
Best thing I ever did was going to see an Ophthalmologist at the beginning of this year. I said an Ophthalmologist, not an Optometrist. An Ophthalmologist is a physician (MD/MBBS or D.O., not OD or BOptom) who has completed a college degree, medical school, and residency in ophthalmology. Ophthalmologists are both surgical and medical specialists. An Ophthalmologist can treat/cure all kinds of eye problems. Cataracts are fixable, Lasik can perform wonders and surgery can be miraculous.
13 years ago I was told I had a fairly rare eye disease (called Salzmann's) that was basically untreatable and would probably get worse. So I forgot about it. In desperation, in January of this year I went to see the Ophthalmologist who cured my wife's eye problems 20 years ago with Lasik. After my eye exam, she tells me that my Salzmann's can now be treated through surgery.
Had surgery done on my left eye in February (2015) and it is like going back 30 years. I can now see the handgun's front sight (and target) clearly out of my left eye !! Since I was always right handed but left eye dominate, I can again shoot handguns like I did up until my left eye started going bad 25 years ago. I am having my right eye done 6/18/15. When it heals, I expect to be able to accurately shoot iron sighted rifles again !!
I cannot stress too much - GO SEE AN OPHTHALMOLOGIST. Ask around for references. If you find one that is booked 3 to 6 months into the future - THAT IS THE ONE YOU WANT. The good ones are heavily booked. It may take 3 to 6 months to get an appointment with them.
Yes, Ophthalmologists can cost more than nail polish or fiber optic front sights, but having your vision fixed - being able to see as well or better than you did 20 to 30 years ago - is priceless.
And a miracle.
