Sunglasses should be an integral part of your visual arsenal.
The benefits of sunglasses are both obvious and subtle.
The obvious benefits of sunglasses is that they help people to see better when the sun is bright. They also protect the eyes from the harmful effects of ultraviolet light, and certain colours have other benefits too.
People with conditions such as glaucoma can benefit from a yellow lens to enhance brightness and contrast. Peopple with macular degeneration have been shown to benefit from lenses with a brown tint. Other people with retinitis pigmentosa can find relief using red/amber or plum tinted lenses.
Polarising sunglasses reduce glare. Photochromic lenses (that darken or lighten depending on the amount of light) provide general purpose benefits.
Sunglasses can help in leisure pursuits too. Golfing lenses, lenses for watersports/fishing, lenses for skiing are all available. Lenses specifically for driving can make a huge difference to the driver.
By making vision more comfortable in bright light, it also reduces the need to squint the eys, reducing the 'laughter lines'!
