About six months ago, I found I had sighting issues with my good (right) eye. Looking through aperture sights, it appears that there is a fuzzy stick coming into the aperture at 3 o'clock, ending in the centre of the aperture with a bulb of bigger fuzz, in other words, completely blocking out the bull. Load testing and shooting enjoyment went into the toilet. So I went to my optometrist for a routine check up and he had very bad news for me. But he recommended a specialist, and eventually, I got my appointment to see him. His news is much better...I have a posterior subcapsular cataract which has made my lens cloudy. He can (and will) replace the lens and says he can give me 20/20 vision. I cannot wait, but wait I must - about four months. Never take for granted your good health.
