From: "Warren, Catherine, RN" <WarrenC@cshs.org> Subject: [kc-link] sunglasses and KC Date: Fri, 25 Mar 2005 11:19:05 -0800 Here's another resource for sunglasses that fit over glasses http://www.fitovers.com/ Sunglasses and KC Bright sunlight often causes problems for those with keratoconus. Sunglasses that wrap around and fit close to the face work best at keeping out sunlight from the sides as well as the top and bottom of the frames. Polarized lenses tend to cut glare best (see info on polarized lenses at the end). This topic comes up often and in the past a number of members of KC-Link have recommended: Nu-polar sunglasses- they have a grade 3 UV lens which can be ordered in various tints, some are light enough to drive with at night to reduce glare. http://www.youngeroptics.com Sundogs http://www.sundogeyewear.com/sundog.html OAKLEY's M-Frame w/ their "Black Iridium" lens - a wrap-around style with very little distortion. Available many mall sunglass spots, or order on line. http://www.oakley.com Bolle' : wraparound and come with two different pairs of lenses, one of them polarized. http://www.historyofshades.com/bolle_sunglasses.html Maui Jim wraparound sunglasses. "Great at cutting glare" http://www.mauijim.com Wiley X Sunglasses as well as goggles. The new modular CQC (Close Quarters Combat) Goggle was developed for military and law enforcement - fits close to the face. They have removable temple pieces that can be replaced with an elastic strap. Use them for soccer, rock climbing, and even racquetball with an amber lens. http://www.wiley-x.com Wal-Mart polarized wrap around sun glasses found usually in the fishing section. They are inexpensive yet are excellent. Concerning polaroid lenses: Reflected light is usually polarized, meaning the light waves are normalized, ie, the magnetic and electric components become arranged so that they are at 90 degrees of one another rather than randomized. Reflected light, of course, contributes to the glare we see off shiny surfaces like windows, water, snow, and painted walls. Polaroid lenses are made with stretched mylar so that they have fibers that are aligned directionally. When normalized light meets aligned fibers, the result is that one half of the glare light is blocked. In other words, Polaroids reduce the glare by one-half. And this is very helpful to KC patients, especially, but also to skiers, boaters, and anyone who works or plays out of doors. Here's a note previously sent to the bulletin board about the lightest (least dark) polarized lenses: These lenses saved my night life! I can wear these at night while driving or during the daytime whenever the lights are too bright (indoors or out). My glasses happen to be non-prescription, but the lenses can be ground as needed by your optician's lab to most prescriptions. I found these lenses at my local optician, whose lab technician does business with Nu-polar. Here's a link to a web site that talks about the Polarized gray #1 lenses from Nu-polar and where they can be purchased: http://www.youngeroptics.com/faq/faqpolar.html http://www.youngeroptics.com/ |
