Runners' sunglasses can be specially made at local eye doctors' offices.
The sunglasses that runners wear are not meant for style or to look good while on the go; they are specialized for performance and efficiency when running during any time of the day. Sunglasses for runners must be high quality and provide top notch protection for your eyes as well as prevent glare in the eyes during running.
Polarized Lenses
Though it is not essential for runners to have polarized lenses, these types of lenses do have the ability to cut down on glare and prevent fogging of the lenses during cooler weather. Polarized lenses will allow runners to ignore the glare off of water, snow and metal buildings. Polarized lenses are specifically meant to cut down on residual light produced from glares making them very useful for runners.
Comfort and Fit
The last thing that a runner wants while in the throes of a run is for his glasses to slip off or pinch his ears. Runners' sunglasses must be a firm fit, but not firm enough to where it gouges into the side of their heads. When trying on glasses, runners should always consider how the glasses feel and if they can sustain bouncing and fast movement without slipping. Rubber nose pads might leave indent marks on your nose, but will be instrumental in keeping the glasses in check.
High Impact and UV Protection
It is absolutely critical for a runner's glasses to be durable in the face of strenuous and movement-rich physical activity. Runners should only use glasses that have lenses made out of polarized plastic rather than glass, as glass sunglasses can shatter easily, especially if they are subjected to prolonged cold weather or excess jostling. The glasses that runners use should also have substantial grade of UV protection to prevent glaring even further and ensure that the glasses do their jobs. Glasses for runners should have 100 percent UV protection to protect their eyes.
Interchangeable Lenses
Though it is not essential to a runner's sunglasses, interchangeable lenses will ensure that if one lenses breaks, you will easily be able to replace it with another one. Because of the wear and tear that many runners' sunglasses tend to go through, having the ability to replace lenses can be very helpful. It is also handy if you find that one type of lenses does not provide you with the amount of protection that you might have liked.
