IMHO G30 is the best all-around cycling lens, period. Not originally designed for cycling, but who cares... This supposedly low-light lens is remarkably competent in bright sunlight. Five-hour rides in the Texas sun are no prob; no headaches. BTW, cyclists need to SEE -- so no, no, no to dark lenses, even on bright days. Wear your black or blue iridiums and try to pick out potholes and grooved pavement at 30mph under an oak canopy at noon on a cloudless July day... In cloudy or mixed conditions only VR28 comes close (actually very close -- it's my next favorite). Haven't used either at the beach or on the slopes -- probably fine for overcast days and headachy on sunny days when reflections can more than double the incident light. Then it's time to pull out the black or blue iridiums!...

The persimmon_g30 is better wen it comes to increasing the contrast,i'm 100% sure that its so,because i have also the g30 and in cloudy/overcast conditions, the persimmon_g30 its a must have lens,the green looks more bright,simply superb for bike riding,and in the woods everything looks more sharp.If u can try a pair with persimmon_g30 and u will find out that im right.Yeah its true that u can wear G30 even during bright sunlight but for that are other lenses so for increasing contrast in cloudy/overcast conditions i will defenetly chose persimmon_g30 :D

Crosshair Brown Chrome G30 Iridium

I must admit these Sunglasses have improved my Golf game by at least 7 to 8 strokes. I usually play early morning or late afternoon. The contrast of the G30 is Fantastic! I prefer my C-Wire Glasses with Tungsten Iridium lenses for Bright Beach days. All in All I love my G30 Iridiums, they do exactly as advertised, Low to Medium Light. Go get Yourself a pair, you won't be disappointed!

I'm not impressed. It's in between VR28 black iridium polarized and persimmon. The VR28BIP offer better contrast while persimmon is brighter for low light. It's not bad all conditions len, just not as i would aspect it to be.

Just got a set of these lenses for the Half Jacket XLJ. Bought them specifically for golf, but found I like these better than the standard dark lenses even for general wear. If you're used to the darker lenses, the pink-ish hue takes a little getting used to when you first put them on. The contrast enhancement is awesome -- especially in the greens and yellows. You notice the difference when you put them on, but the real difference you'll notice when you take them off. Wear them for a while and then notice how dull everything becomes after you remove them.
