Not all bicycles are the same, some are better than others. The same goes for cycling sunglasses.
As a cyclist, you may know bicycles better than bike sunglasses. However, if you read this article, the situation will change.
Here are 10 key facts that cyclists should keep in mind when buying bicycle sunglasses:
Riding a bicycle without wearing a helmet, Just like an idiot. The same goes for cycling sunglasses. Wearing cycling glasses can prevent stones and debris that may fly from the road, dust, and insects. UV400 functions lenses are can better filter ultraviolet rays and protect the eyes.
2. UV400 protection
Most sunglasses will block ultraviolet rays. You know. This is a low standard.
However, some cycling sunglasses cannot provide you with 100% UV protection. You need that. Always choose cycling sunglasses that are labelled as blocking 99-100% of UV rays, or look for a label that says "UV absorption up to 400nm" This is the same as 100% UV absorption.
3. Wraparound design
Wrap-around cycling sunglasses provide more curved lenses that wrap around the sides of the face and cover more area. This design prevents sun rays from entering your eyes from the side. At the same time, it also provides a wider view of sight
The bike design allows you to adjust it according to your body size. Same as riding sunglasses. Xunqi cycling sunglasses provide 8 based curved lenses to make them more suitable for European faces. Adjustable nose pads can fit your face shape better.
5. Lens transmittance grade
As a cyclist, you are exposed to a lot of direct sunlight and light reflected from road surfaces, the darker lens is necessary. I would choose a medium to dark lens level between 2 and 3. If you are in a very bright environment without obstructions, the darker 4x lens will be a good choice. In the morning, please wear clear lenses.
6. Lens colour
Not just pretty colour, blue also shifts and enhances the colour perception. The biggest benefit of the blue lens is versatility, particularly for rapidly changing light conditions such as through forests with intermittent tree cover.
While green can look good, it feels out of place for cycling. During lower light conditions it lends shade, like grey lenses. During bright conditions the shade disappears and although the definition is good.
Red Or Pink
Red and Pink lenses are a wild-card, it is great in low light while for sunny conditions was far better suited than anticipated as the definition and shade also increased.
Grey is usually divided into category 0 (allowing all light to pass through) to category 4 (very dark). Based on visible light transmission (VLT), the most common type 2 (18-45% VLT) and type 3 (8-17% VLT) lenses in cycling.
Although grey colour can help the eyes see things better in bright conditions, it also affects clarity and details are difficult to distinguish. Photochromic lenses that can adjust the tint level according to brightness provide cyclists with more versatility.
Clear lenses are best for night time riding or low light conditions. Cyclists benefit from eye protection; wind, dust and UVA and UVB rays.
The PC lens is lighter, anti-scratch and impact resistance. With the function of UV protection can well isolate the UV rays with a wavelength of 290 nm-380nm.
8. Optional extras or upgrading
Choosing cycling sunglasses lens coatings such as a hydrophobic coating, which repels water (useful in a hot climate), or anti-fog coating useful in a temperate climate or in the cool morning.
The photochromic lens which that automatically darkens in bright light and becomes lighter in low light. Great for early morning rides.
Polarized lenses can be very comfortable in very bright conditions and will cut reflected glare when sunlight bounces off smooth surfaces like pavement or road.
9. The correct way to wear sunglasses
The correct way to wear sunglasses is to wear your helmet, strap it on, and then put your glasses on outside the straps. Not only you look better this way, but you also have the chance to take your glasses off and put them on again during the ride. This might seem unimportant, but there is some occasion in which taking your sunglasses on isn’t helpful or safe.
10. Will the bigger lens be better?
Not completely. Large lenses can provide a wider field of vision and windproof effect. The best cycling sunglasses choosing depend on your face shape and helmet. After all, suitable is the best.
