Sunglasses aren’t just for posing during the summer months, eyewear should be an essential part of your cycling wardrobe throughout the year. The primary reason for wearing glasses on the bike is to protect your eyes. Insects, grit, animal muck and mud can all cause irritation or damage to your eyes and can lead to nasty infections.
Fit is everything, glasses have to be comfortable and not bounce around at all when riding on bumpy roads. All of our faces are different so look for an adjustable nose bridge and arms that you can bend to fit your head and ears. Silicon grippers where the arms contact your head and ears can also make a big difference.
Try before you buy
Although online deals can be tempting, trying on a selection of glasses is the only way to get a good fit so try on a few of your friends’ pairs and pay a visit to your local bike-shop. Once you’ve found a comfy pair, put them through the jumping up and down test. There should be no slipping or bouncing. Next, check how the lenses fit to your eye sockets. You’re looking for a snug fit that doesn’t leave significant gaps for the wind to blast in through.
Don’t forget your helmet
When trying on sunglasses, take your helmet with you. The arms of the glasses should go outside of your ears-straps and the helmet and glasses should not obstruct or hinder each other in any way. Check that when you’re leant forwards, as though riding on your drops, that the frame of the glasses doesn’t obscure your field of vision. This is especially important if you’ll be using the glasses for time trials where your position can be quite extreme.
Although you want the lenses to closely follow the contours of your face, you do want to ensure that there is some airflow around the lenses or, especially when you come to a halt, the lenses may suffer from fogging. Look for lenses with venting slits and/or anti-fog coating.
Interchangeable lenses massively increase the versatility of a pair of cycling sunglasses. Three different lenses should cover most eventualities. You’ll need some dark smoked or mirrored lenses that have a high UV protection rating for those rare bright and sunny days. Next up are some clear lenses for night riding or extremely overcast conditions. Finally, and the lenses you’ll probably get most use out of, are some red or yellow light enhancing lenses for those typically British in between days. As well as brightening up even the foulest day, they increase object definition, which is particularly useful on rough country roads and if riding off-road.
How much to spend
If you go for one of the brands sported by the pros, you could easily be looking at £200 plus by the time you’ve factored in additional lenses. However, before spending this much, think of the life your glasses are going to live. Taken on and off roughly while on the bike, jammed into the vents of your helmet, shoved in a jersey pocket or carelessly flung on the seat of your car at the end of a tough event. It might be wiser to view cycling sunglasses as being “disposable” and opt for a less fashionable brand from who you can get a decent pair of glasses with three lenses for under £50.00.
If you require prescription lenses, you’ve a number of options. The easiest, if you get on with them, is to use contact lenses. Even if you don’t wear contact lenses the whole time, you could get a supply of disposable lenses just for cycling. Prescription main lenses can be very expensive, limit you to brands and models and reduce your choice of lenses. Also, remember what we said about the hard life that your cycling glasses are likely to lead. Some manufacturers produce glasses that a secondary pair of prescription lenses sit behind. This does give you lens changing flexibility but again makes and models are limited and it can be tricky to find ones that fit correctly.
