Choose Quality

Those inexpensive pair of sunglasses and mirrored Ray-Ban knockoffs do block some light, and some may even claim to be polarized or UV-shielded but it’s unlikely they’re both and that makes a difference in terms of your eyes’ comfort and safety. Optical retailers like LensCrafters employ digital technology to customize your lenses specifically to your eyes, ensuring you get a sharper, less distorted view of the world.

UV Protection

Your lenses should also protect your eyes against ultraviolet radiation and harsh glare from reflected sunlight. Selecting wraparound lenses (and frames) offers additional protection by preventing UV rays from hitting your eyes from the side.

Polarization

Polarized lenses have a filter to help improve colour contrast while neutralizing glare reflected by snow, water, road and building surfaces, and other cars. Driving with polarized lenses will give you a clearer view of the road ahead as well as reduce squinting to see through reflected light.

Lens Colour

Different lens tints perform differently depending on the landscape and light conditions:

  • Rose tints. Besides marking you as an optimist, this colour will also help to enhance the greys and whites of snow-covered ski slopes, and make objects more visible against green backgrounds (like hiking in the woods).
  • Brown- or grey-tinted lenses. These provide the  best view for drivers as they are most effective at cutting light intensity—without distorting colours—in moderate to bright conditions.

Seasonal Sunlight

The intensity of sunlight differs on the time of year. In summer, we often think to reach for our sunglasses while driving, yet winter driving also poses its own challenges as light can be reflected by snow- or ice-covered surfaces. UV rays also penetrate clouds, so your eyes are exposed even when it’s overcast.
