Hi Tim,
I would recommend trying the Spotters or any glasses in the actually
situation that you will be using them if that is possible and I think
you will see the difference. I am on board with Spotters as national
pro staff and am more than completely satisfied with their performance.
On the water (ocean) in the conditions we fish here in the northeast I
wear them all day without any eye fatigue. The cripness of what I see
is also amazing and right through the water. I would recommend them
highly for you too, Capt Jim Freda www.shorecatch.com.

I've been looking at photochromic polarized prescription sunglasses for
awhile now, in my quest to find a polarized prescription lens that I
can wear as late in the day as possible. (In general I like a lot of
light - even in the middle of the day, in shadowed areas I often have
trouble seeing well with sunglasses on.)

Does anyone know of any side-by-side comparisons for polarized (I'm
assuming photochromic) lenses that allow for the greatest light
transmission, while still doing an effective job of polarizing? Anyone
have any anecdotal info they'd like to share?

At one point, I tried Spotter Shades, which on their website list their
light transmission as high as 50% (whereas usually lenses top out at
25% or so, meaning, 25% of light is allowed through, 75% blocked;
darker lenses are more like 8% transmission). However, when I actually
tried the Spotters on side-by-side with an Action Optics lens that runs
about 20%, they seemed little different.

Up until now I've been using variations of rose-colored glasses, which
for me seem to do allow relatively more light to pass through during
darker parts of the day. (Though maybe, probably, that's just my
perception.) Yellow lenses obviously work great in low light - but
unfortunately they're pretty useless during the middle of the day, I
also generally don't like how drastically they shift colors, and given
the expense of a photochromic polarized prescription lens, I can pretty
much only afford one pair.

FYI - I use these mainly for fishing for trout, in eastern rivers.

I know this is probably ridiculously specific info to ask for, but if
anyone has any input...?

Thanks, Tim
