Best Answer

Most Allergies to eyewear arise from the nickel metal in eyeglass frames, even frames that claim to be another metal (ie-titanium) usually still have trace amounts of nickel metal in them. If the metal on the frame is turning green where it touches your skin, this is usually a sign of nickel metal allergy.

If you do truly have an allergy to polycarbonate lenses (which I've never heard of) you can just use standard plastic (CR-39) or glass lenses.

Which lenses should you use with rimless eyeglasses?

Rimless eyewear, especially when worn with an anti-reflective coating, is as invisible as you can get while wearing eyewear. If you choose a matte metal in a color that's close to your skin tone or hair color, the glasses will blend in even more. Though the lenses are rimless, you'll still see the bridge and arms of the eyeglasses when you wear them.You may also find that you can't use the regular plastic lenses in rimless styles. Plastic lenses (CR-39) are typically the least expensive type you can buy, but the holes don't hold up well over time when they're placed in rimless eyewear.

Will corrective lenses harm a pilot's face under aerobatic G-loads?

Only at extreme G-loads will corrective lenses become a problem. During normal aerobatic maneuvers, it is uncommon for pilots to be subjected to more than about 3 G's. This is usually acceptable is as far as contact lenses or eyeglasses goes. It should be noted that the air force allows fighter pilots to use corrective lenses, although if contacts are to be used, soft-contact lenses are required.


What principle do eyeglasses use?

Eyeglasses work using the principle of refraction. Refraction means you are bending light. To focus light into a point means to converge it, while scattering light means to diverge it. Farsightedness and presbyopia require converging lenses to bend the light sooner and shorten the focal distance, while nearsightedness requires diverging lenses to make the light converge later and lengthen the focal distance. So eyeglasses move the point where the light rays come together so the light can focus directly on the retina. The retina is the sensitive part of the eye that perceives light and sends it to the brain.
