For the last 30 days I have been trying out a pair of TIFOSI FORZA FC T-V190 sunglasses. These type of sunglasses are real good for different types of weather and for different times of the day specially if you commute at night. This particular type of lense is specially designed for night riding, but I used them for day or night. At only 20 grams they are comfortable to wear. The light night fototec lense (variable tint technology) has a 8.5-19.5 % light transmission. This lense reduces the glare from vehicles and city lights. I even use these glasses when I’m typing on my computer. I can tell a difference at the end of the day, they seem to work like a glare filter. I have tried them to drive at night an once again they reduce the glare of the on coming vehicles and city lights. You can purchase these sunglasses under $60, with a case and micro-fiber cleaning bag, a good price if you ask me. TIFOSI makes different type of sunglasses but for the Bike Commuter I recommend these, specially if you ride back home at night.
