Here is a short physiology lesson for you: Neurons are in charge of collecting and interpreting chemical and electrical signals sent from your brain. Sensory neurons, such as the ones in command of your vision, will interpret those rocks and branches (exogenous toxins) along a steep track, and then fire off impulses to motor neurons to produce muscle contractions so you don't go flying over your bars. The long and the short of it: React faster with Optic Nerve's NeuroToxin IC Sunglasses that offer four different lenses so that your sensory neurons enjoy optical clarity in all weather conditions.

Yep, we said it. Four lenses varying from extreme low light to blue bird days that can be changed as fast as the weather turns. Speaking of change, both the nose bridge and non-slip construction temples are adjustable to fit different face shapes and sizes. The Polycarbonate Lens Resin offers high impact resistance so that rocks kicked up by your wheels don't slow you down. When you're done, store them with your extra lenses in the included hard case. You'll come away with less scrapes and bruises and some happy neurons.
