The EPA recommends that eye protection should filter out 99-100% UVA/UVB radiation. UVA/UVB radiation – UV radiation cannot be seen because it is shorter than the visible light spectrum. One person I knew raved at its ability to cut fog. If fogging is a major problem even with the measures above consider Smith’s goggle with a turbo fan. In addition, your lens should have an anti-fog lens treatment and proper venting. Anti-fogging – At a minimum, your goggles should have dual lenses to create a barrier to resist condensation and fogging.If you wear a helmet, also ensure that the combination fits well together. Comfort and fit – Again go to a shop and try on many different pairs until you find one that is really comfortable and fits your face well.I used Scott goggles for years but recently changed to Oakley due to fit with my glasses. When you are ready to buy definitely consider Oakley and Scott with Amplifier lens goggles. Don’t forget to judge your peripheral vision as well. An eye chart (simply made on a computer) is ideal for this or Oakley recommends using the distance at which three lines blur together as a measure of sharpness and clarity. Also judge the clarity and sharpness of the objects with and without the lens. While in the store (or preferably outside), select several objects and focus on them with and without the goggle to see if it distorts your view.
