What to Look for in Triathlon Sunglasses

Frame Technology


Keeping the sunglasses in place is important because you don't want to expel unnecessary energy in fixing your sunglasses or picking them up off the ground after they fall off your face. A good triathlon sunglass will have grip on three main contact points of the frame. It is commonly found on the nosebridge and on both temple arms. This helps to secure the frames and keep them from slipping.

Choosing a sunglass that fits your face correctly is crucial. An oversize sunglass will have a tendency to move around on your face and a sunglass that is too tight will put too much pressure on your temples and cause headaches. A triathlon sunglass should be lightweight and comfortable since you will be wearing it for extended periods at a time during training and on the day of.

Protection from the sun and elements decreases the strain on your eyes and keeps unwanted debris from getting between you and your end goal. Most triathlon sunglasses will have a wraparound style because it matches the curvature of your face and the curved lenses increase peripheral vision.

Lens Technology


The color of a sunglass determines the amount of light that reaches your eyes. How much light you need access to depends on the conditions you will be running or biking in. A darker lens is preferable on bright and sunny days because you need more protection from the sun. A lighter tint lens is better for overcast, early morning, and evening time. Regardless of color, most all sunglass lenses offer total UV protection. Having a polarized lens helps to reduce glare so if you are going to be running or cycling near water this should be a main consideration. However, we do not always recommend a polarized option because it has been shown to affect depth perception. Finding a darker lens with a mirror will also help to minimize the glare you encounter.
