vision problem
I seem to have a problem with lights when viewd threw plexy glass such as an aircraft windshield. when viewing any bright light threw a windshield i see a ghost image next to the light.for instance on landing i see an aditionl row of lights next to each row of landing lihgts. the second row of lights is faint but distracting. although i dont have a problem passing my first class medical. it is still bothersome. has anyone herd of this

I would go to the local lenscrafters and ask the eye doctor.... I haven't heard of anything like this.... but I know for me my distant vision is much worse at night than day.... I got a long explanation from the doctor which I understood at the time but don't remember a bit of it now.

Assume your military. Did this happen on previous aircraft? Does it occur on various aircraft in similiar conditions, or just one type aircraft? On my current aircraft, the glass angle causes for 'hud' effects (reflecting the ambient instrument lighting into the glass that I found took some getting used too.) Also, what is the runway lighting intensity? Is it always the same? Could ask tower to change intensity to see the effects/impact.

If you're not currently senior to me at Continental, then I'd say that it's just normal refraction caused by the glass.

Thick Plexiglass (acrylic) windshields in light airplanes could easily cause reflections/refractive phenomenon at night. If it's minor, I wouldn't worry about it if your eye doc says you are good.
If you mention this to your AME, you might end up grounded pending further tests.
