If your trade or hobby is outdoors at least part of the time, consider getting tinted prescription lenses with anti-glare protection.
These types of helmets are prone to heavier damage and usage, so finding a helmet that has a excellent venting system and anti-glare visors is a must.
This means that the special anti-glare lenses are able to combat the sun's irritating reflections, giving you the ultimate in comfort.
Coloured anti-glare glasses are provided.
Be especially careful if you get anti-glare coating on them (sometimes referred to as ARC) because the coating itself will scratch.
