I have to dispense a large chap who's sport is a clay Pidgeon shooting. Besides polycarb or Trivex, does any one any other sugestions?
Esp. in the areas of frame selection, tints and lens design
RX: approx -2.00 -0.50

You will find all sorts of info for your consideration.
A lot of sports shooters wear yellow and amber-colored lenses to enhance contrast.
thanks guys - have 1 happy patient now :-)
QD01,
Don't use aspheric designs.

Actually the best lenses for this is Autum Gold, in a past life know as B&L Ambermatic. Unfortuately it is only available in Glass which I am sure none of you wooses would use on a pair of shooting glasses today. It does however go from amber/yellow for early and late lighting conditions to a rather dark brown for mid-day.

I learnt a lot from this customer... the clays are apparantly different colours, and break up in different colours depending how accuratly you shoot them. they are thrown up against any colour sky - from dull to bright, grey to blue, and cloudy etc, and against trees which vary from greens to browns. The referees have books full of coloured gelatines, and pick the best one on the day for the conditions. Picking a coured tint is a nightmare
I was on the 2nd Marine Air Wing rifle team back in the early sixties. We were issues two pair of B&L 14K GF Shooters Decot’s, one pair in Kalichrome and the other G-15. At the National Rifle Matches at Camp Perry you saw nothing else. All lenses were glass – and I dare say that if you used a polycarb you would probably have gone home on Tuesday. As far as I know that holds true today.
The Kalichromes were used under the foggy flat light conditions that frequently exist early in the morning as you tried to get a good sight picture over 500 yards of wet dewy grass. As soon as the ground fog burned off the G-15’s were used for the remainder of the day even if it were overcast and raining.
I would suppose however, that the recreational shooter might be willing to sacrifice visual acuity for supposed safety and wear some material other than crown glass. For sure he would avoid a lot of BS from a dispenser.
Interested.. describe the Kalichrome filterOriginally Posted by rbaker
As I mentioned, the clay pidgeon shooter has to deal with massive changes in contrast, as they track the clay.. from against trees, to against a bright sky for example
Kalichrome was a yellow filter that did not change. The Ambermatic started out as calichrome in low light and turned to dark amber in bright light. G-15 is dark gray~green that transmitts 15% of ambient light (Douglas McArthur type shades).
