(HealthDayNews) -- If you wear eyeglasses, or even sunglasses, you know that it's important that your lenses are impact resistant.
But don't forget the frames.
According to the Canadian Journal of Ophthalmology, a lens in a plastic frame may withstand twice as much force before it cracks as an identical lens in a metal frame.
If you're doing anything that might really risk eye injury, get a pair of industrial safety frames. With an impact-resistant lens, these frames can actually stand up to a one inch steel ball being dropped from a height of 10 feet.
