Hi all,

I do 10m target rifle shooting and i seem to have developed a sighting problem.
Let me try and explain.
As i look through the diopter sight the target seems to fade into the white of the card.
I lose sight of the target through the rifle sight and have to look away for a second and try to aim again.
I guess you could call it "Target blindness".
Ime wondering if the artificial light shining on the target is the problem?
I do have to wear glasses, but i should point out that i have no problem seeing the target in natural daylight and the problem just doesnt occur.
Ime begining to contemplate a visit to see my doctor to rule out any developing sight problem.
Ive also seem the optician and hes assured me that he rates my vision as better than 20/20 vision, so ime mystified as to what is causing the problem.
Has anyone else ever had a problem like this?
Any help or advice would be most welcome as this is playing absolute havoc with my scores, and its putting a bit of a dent in my confidence too.
In advance, thanks for your help.
