I just ordered/received a Polar 3FX Grey Laser replacement lens for my Tralyx shades. Just swapped out to this lens and used it for the first time. The clarity of the optics and lens are fantastic. Not only are my eyes 'relaxed' on a bright sunny day but everything seems to pop and stand out vs other glasses/lenses I have. Ordering process was smooth and received the lens very quickly. End to end the experience was extremely positive and I am super happy with the quality of the lens. Love my Tralyx glasses - they're so light I barely even know they're on!
