The obvious point to make is that if your eyes are properly corrected, then you will avoid eye fatigue. This means keeping your prescription up to date, and ensuring that you have UV filters and/or tints if your sports are outdoor. Polarised lenses are useful if your sport is on or in the water. These lenses cut glare from horizontal surfaces, and make your vision sharper.

The colour of the lens is important if you choose a tint, as each shade does a different job. Grey lenses transmit light evenly, so give true colours. Plump for these if you’re into road sports – jogging, racing, rock climbing. Brown give you excellent contrast and depth perception, ideal for golf, hiking over rough ground, fishing and biking sports. Yellow is great in poor light, giving the best contrast – good for driving later in the day, and for shooting.

For many sports a specific frame is not necessary – golfers for instance will be fine with standard specs, but with a good quality tint and UV filter. Check out sports magazines for suitable frames for your area of interest  – wrap around masks etc give protection for racquet sports such as squash.
