Swiss Arms Extreme Ops Goggles
The most important thing is that you get something that fits your head snugly, offers sufficient protection and that you're comfortable. Beyond that it's simply about choosing lens type (clear, yellow, or smoked).
Yellow lenses amplify ambient light, making it easier to see, however as it tints everything, colours can be harder to make out. Clear lenses offer a simple shield/barrier, and translate the image exactly as you'd normally see it. Smoked lenses offer protection from the sun, however as they limit the amount of light getting through, they are more difficult to see in low-light conditions
The Swiss Arms Extreme Ops goggles are dual-pane polycarbonate lenses certified ANSI Z87.1 giving you the peace of mind knowing that your eyes are safe! The goggles are secured via an elasticated strap which has a rubber lining for improved grip, and also features a buckle for quick & easy detaching when necessary. In the box the goggles come with a helmet cover, and the lens has a strip of protective plastic which needs to be removed before use.
