Lens color - enhance contrast of dark objects?

Postby freeben on Thu Oct 31, 2013 4:18 pm

Hi,
I'm looking for sunglasses that can enhance the contrast for dark/black objects on a lighter surface/background(yellowish/brownish).
Which lens color is the most advantageous? Yellow, blue, orange... appreciate you input.
Thanks in advance!

Thank you for the post. To better recommend a contrast color could you let us know what your intended application for the sunglasses is? It will help us to determine the best lenses for you. Thank you.

I'm a geologist working in desert evironments. I use polarized gray sunglasses but thought there must be better options for distinguishing between darker rocks and lighter background. Maybe someone knows which color can do this job?

There are a lot of sunglasses that can make a light background look darker. Medium type lenses are good for day-to-day wear, but if you use the glasses for very bright conditions, choose a darker lens. Hence, the color and the degree of darkness cannot necessarily determine the ability to block UV light. I can recommend you to look for photochromic glass lens that can darken bright light objects automatically. These lenses can come in uniform gradient tint. However, some of the photochromic lens takes time to adjust in light conditions depending to the type of eye who uses it and the label.
