Clearspecs are available in several styles and levels of magnification. Each pair of these fog-resistant glasses is definitely premium-level quality. The frames are made from grade A acetate (most other readers are B or C). The lenses are lightweight, and feature an anti-fog, hydrophobic coating on both sides. And the hinges are 5-barrel riveted stainless steel โ the same grade youโll find in the most expensive glasses in the industry.
