H-D® Echo - HDECH Lenses
- LA™ (Light Adjusting) Smoke Grey Lenses 2.0:LA™ lenses lighten and darken based on the amount of UV radiation in the immediate environment. As the sun becomes lower on the horizon (early morning, late afternoon or dusk), the atmosphere filters the UV radiation and lenses transmit more light to the eye. With superior optical clarity, these lenses provide a single solution for people who ride all day and night. Light transmission: 15% +/- 3%.
