Allodynia is a symptom of many other conditions in which the body overreacts painfully to normal stimulus. For people with migraine, it can often make eyeglasses too heavy. It can also make contact points (where the glasses touch you skin) seem unbearable. I'm quite allodynic myself . The (sumatriptan) injection, a very common rescue medication, was about $120 without insurance for a SINGLE use twinpack refill. That's about the same price as a pair of our glasses, which can be used indefinitely until they wear out. The pricetag on those sumatriptan shots is excruciatingly painful, but for an allodynic person the concept of touching a sharp needle to your skin can be equally daunting. I used to toggle my sumatriptan injections with the nasal spray, which washes down the back of your throat and tastes terrible. The bad taste isn't quite as bad as the needle stick when you're allodynic.
Because pressure and weight on the face is so important, our optics engineer Dr. Steve Blair has measured the weight of some of our frames for your comparison.
All weights include lenses. Non-prescription Lenses weigh 0.5 ounces by themselves. The weight increases with prescription type, lens material, lens size, and any special treatments applied.
This is our lightest frame.
The Wrap7c is a wraparound frame by 7Eye, maker of ANSI Z87-rated safety glasses for motorcycling, industrial work, and more. These frames have been recertified by the manufacturer with our lenses. The Wrap7c comes in two sizes: Churada (Fits Small to Medium Heads) and Bora (Fits Medium to Large Heads). The AirDam, a patented removable foam insert, blocks peripheral light, dust, debris, and dry eye.
Our new RocketHub frame, when released, will weigh 0.75 oz.
As we work to increase the size of the lenses a bit for more coverage, the weight will increase. (note that two large lenses together weigh nearly 0.5 oz, Rx even heavier).
