For most other sports and activities, polarised sunglasses offer great advantages. And today, many polarised lenses are available in combination with other features that can enhance outdoor experiences.

Besides those who sail, outdoor enthusiasts who benefit the most from polarised sunglasses include skiers, bikers, golfers and joggers, all who may enjoy a clearer view along with elimination of glare.

The polarisation actually cuts out the light coming from the horizontal meridian while allowing in the light coming in from the vertical meridian. In other words, it blocks the light that reflects in from water, concrete or reflective surfaces, reducing glare.

Polarised sunglasses are ideal for driving and, in fact, can reduce glare from a long, flat surface such as the bonnet of the car or the road's surface.

Polarised photochromic lenses, such as Drivewear® which change from dark outside to light inside, are suitable for drivers who are light-sensitive and who frequently move in and out of the sun on any given day.

Sunglass lenses for high performance

Perhaps the most important elements of effective sports sunglasses are the optical quality and visual enhancement properties of the lenses. Many lens tints such as brown, green, grey, yellow and orange are now available, with each colour suitable for specific circumstances. Skiers in snow would want the high contrast provided by amber lenses, whereas grey lenses are best for preserving "real world" colours in bright sunlight.

Polycarbonate lenses are the best choice for high performance sunglasses because they are lightweight, super strong and more impact-resistant than most other lens materials.

Unlimited lens options

Prescription sunglasses are available in all lens materials, including high-index, polycarbonate, standard (CR39) plastic, Trivex® (a lightweight material similar to polycarbonate) and glass. Though glass lenses arguably provide the best optical quality, they are no longer the most popular choice for sunglasses. This is because they are much heavier than lenses made of other materials, and they can shatter easily. However, they are still available if you request them.

Another sun eyewear option is to purchase prescription sunglass lenses that have a photochromic tint.  Photochromic lenses automatically darken in sunlight and then return to a clear state indoors.

Photochromic lenses are very convenient, but they do have one drawback: UV rays are required to activate the tint. Because most car windscreens block a significant amount of UV, photochromic lenses usually don't darken very well inside a car.

For the ultimate prescription eye wear suitable for all lighting conditions, we recommend spectacles with photochromic lenses and a frame with integrated magnetic clip-on sunglasses. The photochromic lenses provide automatic sun-sensitive light adjustments for greater comfort outdoors, and the clip-on sunglasses can be conveniently stored in your vehicle for those bright, sunny days when you need a darker driving lens.

UV and glare protection

As with non-prescription sunglasses, your primary concern when buying prescription sunglasses is that the lenses block 100% of the sun's harmful UV rays.

UV protection is unrelated to the colour and density of the tint in sunglass lenses, so you can choose any lens colour and darkness you like, as long as your optician verifies that the lenses provide 100% UV protection.

For added glare protection from light bouncing back from reflective surfaces (like water, snow, sand and concrete pavement), prescription polarised sunglasses also are available (see sidebar right).

Sunglasses for kids

Children may or may not be as interested as adults in the fashion aspect of sunglasses. However, kids spend much more time outdoors than most adults do, therefore sunglasses that block 100% of the sun's harmful ultraviolet (UV) rays are extra important for children.

In fact, many experts believe our eyes get 80 of their total lifetime exposure to the sun's UV rays by age 18. And since excessive lifetime exposure to uv radiation has been linked to the development of cataracts and other eye problems.

UV rays aren't the only potential danger from sunlight. Recently, researchers have suggested that long-term exposure to high-energy visible (HEV) light rays, also called "blue light," may cause eye damage over time. In particular, some believe a high lifetime exposure to HEV light may contribute to the development of macular degeneration later in life.

Therefore, it's never too early for kids to begin wearing protective sunglasses outdoors and as soon as they begin playing in direct sunlight.
