CYCLING GOGGLES: OPTIMAL VISION AND PROTECTION
The large lenses of cycling glasses make a clear difference to normal everyday glasses. They give you a wide and good view in traffic or off-road. They also protect you more from wind and sun because they close around your face. Cycling glasses are usually made of plastic. This is because the glasses are also supposed to protect you in case of accidents, which is why the special plastic lenses are shatterproof and shatter-proof.
CYCLING GLASSES: THE RIGHT TEMPLES FOR A FIRM HOLD
The temples of your cycling glasses are the be-all and end-all. Make sure you buy the right size. The temples should sit firmly on the ears without pressing against them. A soft and flexible material avoids pressure points. Therefore, you should prefer these earpieces to those made of stiff and hard materials. With a flexible material, you can shape the ends to your liking and adjust them to fit your head. Extra rubber increases the grip of your temples and prevents slipping while riding. If your glasses are too small, they may pinch and restrict your field of vision. If the frames are too big, the glasses slip during the ride and are a nuisance. Therefore, please make sure that your cycling glasses are the right size. A glasses neckband is always a useful addition so that you don't lose your glasses while riding and can remove them quickly if necessary.
CYCLING GLASSES: FILTER CATEGORIES AND UV PROTECTION
For effective protection against UV-A and UV-B rays, your new cycling glasses should be UV 400 rated. If the glasses meet the requirements for this label, UV rays with a wavelength of up to 400 nanometres are reliably filtered, including UV-B and UV-A rays. With a CE marking ("Conformité Européenne") on your cycling glasses, the manufacturer promises that at least UV protection up to 380 nanometres is available - this requirement applies throughout Europe. Another factor is the lens tint. Although the tint does not regulate the UV protection, it does determine how much brightness is transmitted to your eyes. The brighter the ambient light you are in, the darker the tint should be. So for desert areas you would put on darker cycling glasses than for a ride through dark forests. Light transmission, also called glare protection, is divided into filter categories with 5 levels (grades: 0-4):
- Cat. 0: Light absorption: up to 20%, for cloudy, dim light.
- Cat. 1: Light absorption: up to 57%, for cloudy days
- Cat. 2: Light absorption: up to 82%, for plain summer days
- Cat. 3: Light absorption: up to 92%, for bright surroundings, snow or by the sea
- Cat. 4: Light absorption: up to 97%, for very bright surroundings with strong reflection: high mountains or glaciers
⚠️Sunglasses with Cat. 4 lenses are not suitable for driving!
By the way, the different tints also bring different properties:
- Brown lenses provide strong contrasts even in intense sunshine and give you a clear view during your tours. They protect your lenses from bright sunlight and are easy on your eyes.
- For darker light conditions, the yellow to orange lenses are more suitable. They provide additional brightening and are ideal in dull weather conditions, as well as in fog or in twilight or darkness.
- Do you prefer simple protection from insects, wind or dust in all weather conditions? Then go for the transparent grey models. With these cycling sunglasses, you will hardly notice any change in your visibility.
- Blue lenses score particularly well on cloudy days. However, these models are rather unusual for cycling, as you cannot see the colour orange with them in road traffic.
Another quality feature of high-quality cycling glasses is the degree of anti-reflective coating. A distinction is made between simple and medium anti-reflection coating (ET) and super anti-reflection coating (SET). Anti-reflective coating prevents reflections caused by stray light, which can occur when light rays entering from the side or from above hit the inside of the lens. Depending on the manufacturer, a distinction can be made between the type and quality of a glass surface finish. Other frequently mentioned functions of the surface coating of cycling glasses are:
- Anti-Fog (protection against fogging or steam, moisture).
- Anti-Reflex (anti-reflective coating)
- Anti-Scratch (scratch protection)
By the way, many cycling glasses come with replacement lenses in other colours, which you can change according to your preferences and the weather. This way, your new cycling glasses will last you the whole year.
