How to choose your bike Glasses wisely
Here's a look at some of the features offered by performance eyewear:
A special anti-fogging coating is applied to the lens to prevent them from fogging up, especially in cold weather. Others come with specially designed vents that allow any fog build-up to clear quickly.
UV protection is important for long days in the saddle, especially as it can be difficult to tell the damage the sun is doing to your eyes during exposure.
Photochromic lenses automatically change their tint depending on the level of light exposure. While the technology comes at a price, it's very advantageous for those going out into changeable conditions.
Performance eyewear often comes with additional lenses so you can swap between the shades that best fit the needs of the ride, such as extra low-light lenses to improve visibility in the late evening.
A hydroleophobic exterior surface coating is a special chemical compound that repels dirt and stops grime build up on the lens.
Another way to tackle a filthy lens is to use tear-offs. Especially useful when racing or riding at the back of a group in the rain or on the muddy trail, tear offs allow you to pull away a sheet of transparent plastic, giving you a perfectly clear view within a split second. Although they're more suited to goggles, there are some tear-offs available for road cycling eyewear.
Grippers and nose piece
To ensure you have the perfect fit, many professional-standard glasses come with an adjustable nose piece, while silicone grippers along the legs ensure the glasses stay in place during even the most raucous rides.
Which performance eyewear should I choose?
Cycling eyewear comes in all manner of shapes and styles, allowing you to truly express yourself should you feel the need. Whether you want something utilitarian or flamboyant, there's a variety of styles to suit your needs.
Whilst most styles of sunglasses can be used for either road or off-road riding, you should still consider the type of riding you'll be doing. Time trialists and triathletes might prefer to go for rim-less frames so that, from the aggressive aero position, there's nothing in your line of vision. Winter commuters and those who enjoy night riding might prefer a clear lens or a style that comes with interchangeable lenses to cover all conditions.
