polarized fitover sunglasses
I went to REI this week looking for glacier glasses, or at least some way that I could augment my own prescription glasses for above treeline use in winter. I have a pair of OTG ski goggles that I use when it is extremely cold and windy, but I prefer using regular glasses or polarized sunglasses in milder weather because they are less prone to fogging. The problem is that my current prescription sunglasses don't provide the extra side protection that you need against snow glare.
Additional eye protection is very important in winter if you are hiking or climbing on snow. Snow reflects 85% of the ultraviolet radiation cast by the sun and not protecting your eyes can lead to snow blindness. This is a painful condition where it feel like there is grit in your eyes and can even lead to temporary blindness in severe cases.
If you are a prescription glasses wearer like me, you need to look for three things in a pair glacier glasses.
...For 2011-2012, Fitovers Eyewear has evolved in product development and its online presence to meet consumer demands. The Nagari Collection has been designed to worn over prescription eyewear and includes six new styles without side lenses.
“This new direction without side lenses has been long awaited and has been very well received by optical professionals and consumers,” said Paul Stables, designer and president of Jonathan Paul Eyewear. “A younger consumer has embraced the collection simply because it looks like normal sunglasses and is styled and coloured to beg to a younger consumer.”
The Nagari Collection also features optically correct polarised lenses, coated with multiple lens treatments, along with value-added accessories that include a carry case, neck cord and micro-fibre cleaning cloth. All models are priced between $74.95 and $84.95.
Fitover Eyewear has also launched a new website featuring a “Virtual Try On” commitment.

Only use filters that fit over the front of the telescope. Never: look at the sun through sunglasses or stacked negative film. No matter how dimmed the sun may look through these items, dangerous infrared and ultraviolet light will pass right through. |
You can also buy "solar shades," special glasses widely present from telescope stores before eclipses. Do NOT use standard sunglasses or any kind of homemade sun-shading contraption. The safest and simplest technique is perhaps to watch the eclipse

It is also possible to get clip-overs, which are made from sun lens materials but fit over your normal prescription glasses. While all prescription sun lenses will automatically offer good UV protection, it is now possible to get high-performance sun |
