Shooting glasses come in several colors. Sights come in a variety of coatings and with several different colored lens caps.
What is the purpose of the different colors? Is this just personal choice? I have heard that yellow allows shooters to see better but I don't remember the reason. I have heard that rose color is best in low light, but I don't know why.
I oftern wear my glasses to the range and often wear sunglasses due to my sensitivity to light. Is there some reason why I might consider buying special shooting glasses?

Can't answer for sure on the rose colored part, but the reason for the yellow
tint is to filter out some of the blue light. Blue light is the shortest wavelength
and is more easily diffracted by tiny water droplets and the dust in the air.

--That is actually why the sky is blue.
If the atmosphere were perfectly dry and dustless,
it would be practically invisible,
and the sky would appear black.
Ever notice how much darker blue the sky is at
8000+ elevations in the mountains??

Sunsets are red because the sunlight has to cut through
a larger path of the atmosphere, and the red wavelengths
are not diffracted quite as much. What happens to the
sunsets when there is a forest fire somewhere near??

Yellow lenses absorb more of the blue light and increase the contrast.
Brown lenses will also do this as well, but cut a larger proportion of the total light
and would be best for use in bright daylight conditions.

In general, contrast between the target object and the background is really the important part.

See! I actually did learn something at college......
--Or at least, I didn't forget all of it....

Arthur_500,

I got my (yellow lens) shooting glasses just last year. Mostly because I needed an additional tri-focal for pistol sighting. I had a selection of four different colors for hunting/shooting. I'll list the four from the chart the doctor used and maybe it will help.

1. yellow - any background - overcast, hazy (night shooting).

2. orange - open, uncluttered background - average sun, overcast.

3. violet - green or cluttered background - average, bright sun.

4. red - green, sky, cluttered - average, bright sun.

Note: The only two colors listed for any background are yellow and green. Also, keep in mind that the target will be a different color depending on the lense color. Personally, I doubt you could go wrong with a yellow shooters lense.
