Five Things You Should Know: High Index Eyeglasses
For many people, the weekends aren't just for sleeping late and spending time relaxing around the house. They are weekend warriors who engage in a sport or other vigorous activity in their spare time, usually their weekends.

It's only a matter of finding goggles that provide a good and comfortable fit over your glasses. Because high index lenses are lighter and thinner than the old bulky "coke bottle" lenses, they will fit better inside goggles. Because so many people wear glasses, it's no surprise that many manufactures provide goggles built specifically to accommodate
