* If the recommendations for weather and activity conditions are different, please take the priority of No>Best>Good>OK. For example, if you are cycling under low light condition, the recommendation for Mr. Shield lenses is “Best” for cycling, “No” for low light. Please take the recommendation of “No” because of “No”>”Best”. It means you should not use Mr. Shield lenses for cycling under low light condition. The recommendation for Yellow lenses is “OK” for cycling, and “Best” for low light, so you should take the recommendation of “Best” because of “Best” > “OK”, it means you should use Yellow lenses for low light cycling.
