SERENGETI...In fact, for those of us who have to 'tweak' the correction a bit from being at the game a few years....I have had a couple pairs of custom SERENGETI corrected lens sets made! I have flown with this type of lens for over 12 years and haven't found anything to replace them with. The tinting takes out the excess UV coloring. Next time try this experiment when flying in dirty weather (and not close too the ground)....notice the contrast, depth and distance you get without a good set of Serengeti tint lenses....then, put the lenses on and look at the difference. It very noticable, in fact, the extra distance and definition you can get through this lens color is enough to make a sucessful CAT II / III landing because of the better acuity. The drawback is price, but like a good headset, its all part of the tools of the trade.
Happy New Year, gang. Lets make it the best year for safety!
