Gadgets: Sun, wind, splash, dust, insects or gravel – it is much that can interfere with your eyes on the bike. Think smart when you buy your bike glasses. We tested nine hot glasses.
The Sport Optics on Kungsgatan hanging hundreds of pairs of sports custom glasses on the walls. Here we took our test glasses to see an optometrist who specializes in just sporty use.
– The most important thing is that the glasses fit well without bobbing or slipping down the nose. The easiest way is to choose a pair that are lightweight and adjustable nosepiece. If it is possible to adjust the arms is a plus, says Lars Wülfing Sport Optics (see http://pauldigo.com/sunglasses/quick-guide-for-choosing-sunglasses/).
An optician can also using heat to bend to the sides so that they suit you. To adjust and adapt is relatively difficult and it might be nice to let a pro bend your expensive glasses. In addition, see an experienced optician quite directly what needs to be adjusted.
It is also important that the glasses will work with the angle of your head that you have when you sit in the saddle and look forward. Some models have a frame at the top edge may end up being just in the field of view if you are unlucky.
When you test the glasses, it is also important that you do it together with the helmet (or helmets, if you have several). If you are not dealing glasses in a store and with your helmet, make sure to have good return opportunities.
The lens then?
– The ideal lens for most conditions is a photochromic that change color based on the sun’s brightness, which works the same lens in any weather, says Lars Wülfing.
Things to consider when it comes photochromic lenses is that they do not always keep up with the rapid shadows if you ride in the woods, where you also have to keep an eye on how the surface looks.
UV protection is not something you really need to think about. It is only through glasses with blue colored contact lenses that do not have 100 percent UV protection. Blue mirror on the other hand is good if it sits as a film on a lens that is not blue. All glasses in the test is 100 percent UV protection.
– All modern sports glasses of good quality have a good UV protection, but those who have a yellow-orange-brown tone will effectively remove the blue light and thereby to fatigues the eye less, says Lars Wülfing.
If you everyday wear glasses, it is possible to grind the lens that sits originals of several manufacturers. Need very large correction, you may have a loose bet that you attach inside your sports glasses.
Lens. The lens is made of plastic. Most manufacturers have their own names on the plastic, but usually it is polycarbonate or NXT plastic that hides behind the cool names. Light transmission graded from 0-4. 0 is transparent lenses and 4 are darkest. All categories should protect as much against UV radiation. Is the lens CE marked fulfills the requirements for UV protection. Photochromic lenses change the ambient lighting conditions. Polarized removes glare from wet surfaces. Yellow and orange lenses produce contrasts. Most manufacturers have their own name for their particular lens, and the qualities that prioritized when they composed the paint. Many lenses can also grind to fit myopic.
Arch. It is usually made of plastic. Some frames have a sweat brake at the upper edge and replaceable rubber parts in the nose piece and temples. There are also models with an attachment for a mini bow with ground glass.
Arm. The arms are part of the arc. It is the rubberized they sit better. Many models are also bending or adjustable to adapt better to the shape of your head.
Nosepiece. Usually made of rubber and can easily be adjusted to fit different noses.
