Hobie’s Eclipse Photocopper sunglasses not only protect you from glare (the most concentrated ray of light the sun can deliver) but they are also highly effective for spotting fish. The blue-light blockers in the polarized photocopper lenses provide clear, sharp vision while eliminating 100 percent of harmful UV rays. To reduce eye fatigue, the lenses will lighten or darken to accommodate the right amount of light, rain or shine. Hobies come in three highly durable frame series, with 36 individual frame styles; lenses can be custom-ground to virtually any prescription. About $140 for non-prescription glasses; call 800-554-4335 for dealer information.
