What is the best lens tint colour to use?

Frequently Asked Questions
Brown and grey are the most popular tint colours. Brown is the best colour overall because it allows the wearer the widest light spectrum through to the eye, while blocking blue light and offering optimum contrast. Brown is great for applications where distances need to be constantly judged, like tennis or golf or skiing or other sports requiring acute visual perception and contrast differentiation.

What is the best lens tint density to use?

Frequently Asked Questions
Tint density is defined as a percentage, where 0% is completely clear, and 100% permits no light to pass through (solid). We offer three tint densities: A 50% tint is used as a general all round tint for outdoor protection from the sun but not extreme light situations such as midday sun on the water.

Which lens color is the best?

FAQs: Sunglasses, Types of Sunglasses and Buying Sunglasses ...
Color is a personal choice and doesn't affect how well the lenses protect your eyes from UV light. Gray and brown are popular because they distort colors the least. Athletes may choose other tints for their color-enhancing properties; for example, yellow lenses are popular with skiers and target shooters because they work well in low light, reduce haze, and increase contrast for a sharper image.

Question: -- What is a Barlow lens and how do I use it?

Telescopes FAQ - How to Setup & Use a Telescope
Answer: -- A Barlow lens is a lens that you use with your eyepiece. A Barlow lens will double (2x Barlow) or even triple (3x Barlow) the magnification of any eyepiece that you attach to it. To use a Barlow lens, remove the eyepiece from the focuser, insert the Barlow and then insert the eyepiece into the Barlow. Remember, though, that a Barlow is best used with low magnification (long focal length) eyepieces. See similar questions...

What colour is best and why are there so many colours?

Hot Spot Lures - F.A.Q.

If we think of the water column as a light filter the red end of the spectrum will reflect light as red only to about 30' in saltwater, and then as depth increases, red becomes black. On the opposite end of the spectrum blue and purple will reflect light as those colours at depths beyond a 100'. See similar questions...

Why don't you use a polycarbonate lens?

Ocean LED - Frequently Asked Questions
We do not use plastic or polycarbonate lenses from results of extensive long term testing. They do offer great strength but will cloud overtime in salt water and can be very easily scratched diminishing the light output. It is impossible to polish the surface back to new, unless a flame is applied which should only be done by a plastics specialist. It is no longer a simple case of power. It comes down to design, technology and size. See similar questions...
