Mau Jim Sunglasses


Sunglasses are a great fashion accessory. But besides providing style, quality sunglasses do much more:

 

1.      Sunglasses protect your eyes from harmful UV rays. 

Exposure to ultraviolet (UV) radiation from sunlight has been associated with the development of cataracts and age-related macular degeneration (AMD).  Quality sunglasses protect your eyes by blocking 100 percent of the sun's harmful UV rays.  Sunglasses also protect the delicate skin around the eyes from UV rays that cause wrinkles and premature aging. 

 

2.      Sunglasses reduce glare. 

All surfaces reflect light.  Surfaces like water, snow, and automobile windshields can cause extremely bright reflections that are distracting and can interfere with vision.  Reflective glare is particularly dangerous when driving, riding a motorcycle, skiing, or boating.

Sunglasses reduce glare for safer, more comfortable vision.  Polarized sunglasses are particularly effective at reducing glare from surface reflections.

 

3.      Sunglasses protect your eyes from wind, dust and debris. 

Sunglasses are an effective wind barrier.  Wearing sunglasses reduces the rate of evaporation of tears and helps keep your eyes moist and comfortable.  Sunglasses also help keep contact lenses from drying out and prevent windblown particles from getting in your eyes and causing a corneal abrasion. Sport sunglasses are particularly effective at reducing the potential for dry eyes and eye injuries from windblown particles.

 

4.      Sunglasses can also reduce headaches and eyestrain. 

The pupil controls how much light reaches the light-sensitive retina in the back of the eye.  In dim light, the pupil increases in size (dilates) to allow more light in.  In bright light, the pupil constricts to keep too much light from striking the retina. 

In very bright conditions, the pupil cannot constrict small enough to reduce light to a comfortable level. This causes a person to squint.  (Squinting reduces the space between the upper and lower lids to further reduce the amount of light entering the eye.)  Muscle fatigue associated with squinting and constant constriction of the pupil can lead to headaches and eyestrain.

Sunglasses reduce the amount of light reaching the eyes to a more comfortable level, eliminating the need for squinting and severe pupil constriction.  This increases comfort and reduces the risk of headaches and eyestrain.

 

 

Photochromic lenses

Photochromic lenses are lenses that change their colour according to light conditions. When exposed to sunlight they darken quickly to eliminate glare and to protect the eyes against UV. These lenses are generally nearly clear when it is dark.

Why wear photochromic lenses?

Many people wear these lenses and find them convenient, as they automatically darken in the sunshine and can avoid the need for you to carry prescription sunglasses. Modern photochromic materials react and fade quickly, suit most prescriptions and are now more likely to be made in lightweight plastic than glass.

Why not have your spectacles made in Transitions® - the latest in photochromic technology. Great for outside but also great for normal every day wear. They now change from light to dark in approximately 20 seconds.

Polarised lenses

Polarising lenses eliminate 99.9% of glare from horizontal surfaces such as roads, water and snow. They give improved vision and comfort with 100% UV protection and are ideal for driving, water sports and fishing.
