If you experience migraines or light sensitivity, FL-41 tinted glasses can make a real difference in your daily comfort. The FL-41 lens filters out the wavelengths of light most associated with triggering migraines and photophobia — especially harsh fluorescent lighting. While they won't prevent a migraine, they can help reduce discomfort and make everyday environments more tolerable.
The Cool Classic 004 overfit glasses are designed to wear comfortably over your existing prescription eyewear, so you never have to choose between vision correction and light protection. The sleek black fade plastic frame offers a modern, low-profile look that fits discreetly over most frames. Lightweight and easy to slip on and off, they're ideal for everyday use at work, on the road, or anywhere harsh lighting is a concern.

Find Your Size
To find the best fit for your glasses, first you should look for the perfect Frame Width. A that's slightly wider than your face is a good place to start - no more than a finger width between the temple and your face is a good rule of thumb. If you've already got a pair of glasses that fit, measure from screw to screw on the face front for a good idea of the frame width.
Other Useful Measurements
You'll also sometimes see other measurements on the temple (arm) of your glasses. These represent the lens width, bridge width, and temple length (all in millimeters). Use these measurements to compare with your current glasses or to find your ideal fit.
