What is needed in Aviation Sunglasses?
Aviation sunglasses should be non-polarized for two reasons. One, we need to see traffic, and thus do not want reflected light from the wing or fuselage of that potential traffic to be eliminated. Secondly, polarized lenses can interfere with some of the glass panels of the modern instrument panel. The tint of an aviation sunglass should not be so dark that visibility within the cockpit is compromised. Further, lenses that darken with sunlight generally do not lighten fast enough in changing light conditions, such as going from bright sunlight into a cloud layer. Of course, since ultraviolet radiation increases at altitude, sunglasses must provide full UV protection. For more information, see FAA publication, "Sunglasses for Pilots" and "Sunglasses in Aviation" from the American Optometric Association.
What are the relative properties of the various lens materials?
Where are Hazebusters made?
They are made in Taiwan and China.

What is Acrylic?
It is a term for acrylic plastic, similar to "kleenex" for tissues or "lexan" for polycarbon. The full name is "allyl diglycol carbonate acrylic."
Will these scratch or break?
The glass lenses are very durable, even if you use a paper towel to clean them. If you are especially hard on your lenses, this is the right material for
you. The two plastics, acrylic and polycarbon, have scratch resistant coatings,
but you must use a wetting solution when cleaning them, along with a microfiber
cloth (we provide one with each purchase). Taking care in the cleaning process
is especially important to preserve the anti-glare mirror coat on the backside
of some of our products. Of course, anything can be broken. Treat our frames
and lenses with appropriate care, and you will get years of service from them.
Will the color come off of the lenses?
No. The Hazebuster color is in the lens material. It is not a coating.
Are they UVA and UVB rated?
Yes. Our lenses block 100% of both. UVC coating is not necessary because the ozone layer stops 100% of UVC rays.
What makes them so good?
The high definition lens (see Hazebuster Lens page). One of our competitors also promotes a high definition lens, but ours is about 1/2 the cost of theirs.
Can I wear them at night?
Sunglasses, of any type, are not recommended for nighttime flying.
How do I choose the right bifocal power?
There are two distances to consider, so determine your primary need. Do you want to read your panel, or do you want to read a handheld GPS, checklist, or a map? If you already wear reading glasses, the power may be imprinted on the temple. This power would be appropriate for something you would hold about 18 inches away, like a book, a handheld GPS, or a checklist. If you want to read your panel, you will need a slightly lower power--the further away you want to focus, the lower the power you will need. Not sure how to select a reading power? If you think you need a small amount of correction, start by trying on a +1.5, then try on a +1.25 (better or worse?), then try on a +1.75 (better or worse?). If you have been using readers for a while, but do not know your power, you can try a higher magnification to start with, and go on from there.
Why does the lens color look slightly different from one frame to another?
The lens will appear to be a slightly different tint from one frame color to the next (e.g. it will look slightly different in a black frame vs. a gold frame), and the background it is displayed against will also make it look different. Also, the lens materials (acrylic, glass, or polycarbon) accept tints differently. Although there may be a slightly different look, the vision through the lens is the same.
