Performance and Health Benefits to wearing sunglasses.

1. UVA/UVB lens protection. This lens feature blocks out the sun’s harmful UVA and UVB rays which can cause macular degeneration, cataracts and other eye diseases. without this protection, the darker lenses make your pupils bigger. This allows more light in and even more harmful rays – the opposite of what you want!

2. Polycarbonate lenses or Trivex lenses offer full face protection Both polycarbonate lenses and Trivex lenses are thinner and lighter than regular plastic lenses. They are up to 10 times more impact resistant than plastic or glass lenses.. Polycarbonate lenses are much more flexible and can absorb flying objects’ impact than glass. A wrap-around style that curves along the sides of your face will block even more sun, dirt, and those pesky summer mosquitoes from infiltrating your vision. If you are a contact lens wearer, wrap-around styles provide a better protection from wind at high speeds. Your eyes will feel fresh , not as dry and will not require eye-drops.

3. Polarized lenses or Specific lens tint Polarized lenses offer the following advantages over non-polarized sunglasses.

• Improves visual comfort

• Improves contrast and visual clarity

• Reduces eye strain

• Allows for true perception of colour

• Reduces reflections and eliminates glare

Some cyclists avoid polarized lenses to better spot oil spills and puddles on the road. There can also be interference with the LCD display on some bike computers. However, this can be remedied with a slight tilt of the head. Polarised lenses do reduce reflected glare off the road and enhances vision , making it more comfortable as glare is a fatiguing nuisance. It is a personal preference as to whether a cyclist should choose polarized lenses or not.

The right lens tint : can make all the difference in spotting those rocks, nails, and other flat-tire causing demons lurking in the bike lane by increasing your vision’s color contrast. Here’s the best lens tint colors for the given conditions:

• Bright & Sunny:Grey and green

• Overcast: Copper and amber

Cloudy & Nighttime: Yellow and clear

4. Correctly fitting frames

Enduring Fit An enduring fit is required for longer rides, tighter fits become more noticeable. A lightweight frame with rubber grips will prevent slipping on your hotter rides. The smaller the nose piece, the better, because combined with a half-rimmed style, your peripheral vision is clear to see what’s in front of you and those crazy right turners to your left.

Ventilation and Padding: Ventilation , padding, and an elastic strap will improve both fit and vision. The padding will increase distance between your face and your lenses, which will help prevent your lenses from fogging up. Just like rolling windows down in your car, vented lenses and frames will help with fogging too.
