Indoor Air Pistol - Lighting

I shoot air pistol indoors under lights.
Our club regularly checks the light meets or exceeds minimum standards.
I was wondering if we might have too much light over the shooting positions, as I have a very ghosty effect on my fromt sight which doesn't happen outdoors, under cover.
So - can too much light be bad?

Oh, yes, too much light is bad. Do you have filters for your shooting glasses?

although a brightly lit indoor range (double would still be under 1000 lux on the sights and 2000 lux on the target) hardly compares with indirect outdoor daylight of 10000 - 25000 lux.
Does your club have any diffusers over the lighting?

My shooting glasses are a pair of prescription glasses with the non-dominant eye having an ISSF compliant blinder (old translucent milk bottle piece). I usually use a merit attachment, and wear a hat to keep glare out.
The flouro tube above the firing line do not have diffusers, however they are twin tubes.
Some of us at the club are discussing removing one of the tubes.

I thought the lighting at the target had to be 1500 Lux, this is what I understood from the rules.
6.3.15.4 Indoor 10 m ranges must have artificial illumination providing the
necessary amount of light without glare or distracting shadows on
the targets or firing points. The entire area must be evenly
illuminated with no less than 300 lux. Targets must be illuminated
evenly with no less than 1500 lux. The background area behind the
targets must be a non-reflecting, light even neutral color. If due to the
request from the media, the lighting on the firing points has to be
increased, then the light on the targets must be appropriately
increased.

You shooters who can quote the rules by number certainly know your stuff.
The target lights - no problem
I was just concened about the effect of too much light on the front sight - hard to see just 1 solid lump on the pointy end of the gun.

1000 should be 1500 - fingers faster than the brain...
Leave those fluro tubes at NPC alone (or the grumpy eater might get you)
Re the fuzziness: a check for glaucoma might be a good idea.

Best thing to do is turn off or block out the overhead lights and see if that helps you. I get glare or fuzzyness if there's too much overhead light. An eye test might also be in order but also a too narrow rearsight aperture can cause fuzzyness on the foresight. Lastly make sure fore and rearsights are clean and well 'sight blackened'.
