| | | Anti reflector on glasses
Flourescent lights make my eyes turn red.
In your opinion, will the anti reflector or anti glare feature prevent my eyes from turning red.
Thanks in advance.

| An anti-reflective coating will help relieve the pain from glare from flourescent lighting, so yes, I think it would be extremely beneficial to you. |

| Are you currently wearing glasses?
Florescent lights emit UV because of a little mercury in the tube. This excites phosphors that emit visible light.
Most fixtures have a plastic cover and plastic generally blocks UV. Most glasses are plastic and therefore most of the UV is blocked.
They also have a high intensity peak of light. Light output is not sinusoidal.
Wide spectrum light bulbs sometimes help people as well
If this is in conjunction with watching a TV or video monitor, then your eyes might be seeing flicker between the 120 Hz ( 2* 60) and the refresh rate of the monitor.
I'd see if the problem goes away by wearing polarized sunglasses first. | |

| Wearing polarized sunglasses indoors seems to me would cause other problems.
When someone is complaining of an issue like this, at any optical establishment they would be recommended to use an anti-reflective coating, and perhaps a light tint or a transitional lens. | |

| My intent was to not make it a permanent solution, but to have a cheap place to start. You can even get mirrored sunglasses which would act as an ersatz AR coating.
If glare does it, this could be useful information too. | |

| She didn't ask for "a cheap place to start", she asked if an anti-reflective coating would be beneficial to her. | |

| I am allergic to flourescent office lighting. I found that when I got the anti glare coating my headaches vanished as well as my eyes bothering me from that kind of lighting. They put the coating on when the glasses are made ideally. I don't know if they would be willing to coat existing glasses but you could ask. I did find that the transitions lenses were useless indoors to help with the flourescent lighting problem and have stopped wearing them years ago. | |

| They won't coat an existing lens. But anti-reflective is highly effective for anyone that has to be under flourescent lighting. | |
