To select a viewing power, consider how you will be using your Dual Eyewear. If you are a cyclist, motorcycle rider, or driver looking for a clear read of instruments, you might want to consider a magnification that is a bit weaker than what you use to read a book. For example, if you use 2.0 readers at home or at the office, try a 1.5. This drop in strength will not hinder your ability to focus on small text items like your cell phone or a menu at a restaurant.

To prolong the life of your Dual glasses or any other eyewear, we recommend you wash them with a mild dishwashing soap at least once a week, especially the frames. Rinse lenses first with water to flush off any dirt particles, apply small amount of soap and lightly rub the lenses and frame with your fingers and rinse. Do not use paper products to dry the lenses, this will scratch the lenses over time. We recommend drying them with a microfiber cloth.
