Dual Power Eyewear SL2 Glasses

By Jim Langley

Dual Power’s SL2 glasses are perfect for roadies who require readers. They only cost $49.95 but boast all the features cyclists need, plus spot diopters (overlaid magnifiers on the bottom of the lens) that let you read the fine print on a computer when you’re riding and check a cellphone and read maps, etc., when you’re stopped.

Using the SL2s made me realize how much I’ve been missing on rides as my eyesight has weakened. I carry reading glasses in my jersey pocket, but I rarely take them out and use them. In these “biker’s bifocals,” I could easily read the smallest text on my PowerTap computer — even at sunset. I could also see to help fix my friends” bikes on rides. Plus, I could leave my reading glasses at home, saving space in my pockets for other essentials.

And these are nice glasses that weigh next to nothing at 20 grams, have rubber grips that keep them in place, offer 100% UVA-, UVB-, UVC-protective shatterproof and scratch-resistant polycarbonate lenses, sport flexible impact-resistant Grilamid TR 90 frames and a stylish full-coverage wrap-around design.

The only thing you’llneed to know to get a pair for your cyclist is the strength of their reading glasses. The SL2s come in 1.5, 2.0 and 2.5 spot magnification. They also come with a 30-day money-back guarantee. I think they’ll be a huge hit. I’ve even been wearing mine in the car and walking around because it’s so convenient not having to change glasses to read something.
