Road cycling glasses

Filter category: which tint for which light

The ISO 12312-1 standard classifies sunglasses into five categories. Category zero, almost clear, is for dark conditions; category three, the most common, is suitable for bright sunlight; category four, reserved for high mountains, is unsuitable for road use. A photochromic lens shifts from one category to another according to the ultraviolet light received: the KOO Alibi moves from category one to category three, letting through two-thirds to about one-sixth of the light. For an outing that begins at dawn and goes through woods, this is the most flexible compromise, without needing to carry a spare lens.

Sweet Protection Memento: polarized or RIG Photochromic

Sweet Protection, a Norwegian brand established in 2000 in Trysil, has developed its own RIG lens technology that enhances contrasts while minimizing color distortion and visual fatigue. The Memento RIG Photochromic combines this with a lens that adapts to brightness, treated to be hydrophobic and oleophobic to repel rain and fingerprints. The Memento Polarized filters out reflected light: it eliminates glare from a wet road at the end of the day, although it may make some bike computer screens less clear. Its TR90 polyamide frame weighs around thirty grams and the lens can be changed in a matter of seconds.

KOO Alibi and Rudy Project Cutline: half-rim and prescription

KOO is the eyewear line from the Italian helmet manufacturer Kask. The Alibi features a half-rim construction made of Grilamid that leaves the bottom of the field of vision clear, useful in a low position on the handlebars, and comes in a Regular size for smaller faces and Large for wider faces, weighing around twenty-five grams. Its lens receives an anti-fog treatment. Rudy Project, another Italian brand, offers the Cutline with an optical clip that fits behind the lens and holds prescription lenses: you maintain the wraparound protection of sports glasses without needing to wear contact lenses or prescription glasses under the helmet.

Frequently asked questions

How long does it take for a photochromic lens to change tint?

It darkens in less than a minute in the sun and lightens more slowly, taking a few minutes. Cold temperatures enhance the tint and slow down the return to clear, noticeable during morning descents in winter.

What size sunglasses should I choose for a small face?

The lens should cover the field of vision without touching the cheeks or extending too far past the temples. A Regular version, like the one on the KOO Alibi, is suitable for slim faces, and the arms should not interfere with the helmet.

How can I prevent fogging on bike sunglasses?

Choose a lens treated with anti-fog and a frame that allows air circulation around the eyes. When stationary, place the glasses on the helmet rather than on the forehead: the heat from the face fogs them up immediately.

Do I need UV sunglasses when cycling in overcast weather?

Yes, a large portion of ultraviolet rays penetrate through clouds. A lens that filters out all UV rays protects the retina during long rides, and a photochromic lens lightens to maintain clear vision under a grey sky.

How do I clean bike sunglasses without damaging the treatment?

First rinse the lens with clear water to remove dust, then wipe it with a slightly damp microfibre cloth. Paper towels and jerseys can scratch the lens and wear off hydrophobic treatments.
