Malachite Polar

88-89% density (11-12% VLT) (Standard 80% also available) Polarizing offers relatively glare free vision. The more neutral gray-green base provides truer color perception but is less forgiving in hazy or lower light conditions. Good for sunny driving, leisurely hiking, deep water fishing and other outdoor activities. Polarizing is NOT recommended where accurate judgement of surfaces and terrain is critical (jumping crevasses, hanging from ropes). Polarizing can cause some LCD displays to black out. Available in plastic and NXT, single vision and progressive. Some prescription limitations may apply on NXT availability.
