People today usually have some comprehension of the damage that continuous and frequent sun damage can have on the skin, but they don't always think about the effects on the eyes. Light comprises of invisible wavelengths that can also cause eventual harm to your eyes. These waves can be split into visible, and high energy visible (HEV) light that induce ultra-violet (UV) damage if you don't protect the eyes adequately.
While visible light is the part that gives the perception of colour on the eye, HEV is the upper end of the spectrum in the violet blue band approaching ultraviolet. Extreme exposure to ultraviolet waves may have effects later in life and can lead to macular degeneration.
Ultraviolet light waves are electromagnetic radiation that is found to be stronger in higher altitudes or in open highly reflective conditions like water, snow and sand. Ultraviolet waves can be split into three types of light, UVA, UVB and UVC. While many are aware that excessive exposure to ultraviolet waves leads to sunburn, there are more damaging effects to health that could occur, particularly on the eyes.
UVA (often called longwave or black light) penetrates the skin and eyes and may cause untimely aging. It has also been linked to short term eyestrain and fatigue.
UVB (also known as medium wave light) is easily the most damaging of the sun's rays and is regarded as a factor in retinal damage and the development of cataracts. Ultraviolet B waves are also connected with other concerns that can bring about eye disease and perhaps blindness.
Ultraviolet waves of the C subtype (also known as shortwave or germicidal light) aren't a particular problem to the eyes, as they are mostly absorbed through the outer atmosphere before reaching the planet earth. UVC radiation is usually found in artificial sources including germicidal light and mercury arc lamps.
Keep in mind when choosing sunglasses to look for those that have 99-100% protection against UV damage.
It's not necessarily all bad news, of course some exposure is certainly beneficial to your health. The only thing that people should understand is that for health purposes, moderation is highly recommended when you're in direct sunlight.

About the Author:
Designer Sunglasses really should not be excluded when looking for UV damage protection for the eyes. Most designer sunglasses are high quality,exceptionally well made and subject to years of technological research. It is not just the brand you are purchasing, it's the quality and research of, for example, Oakley sunglasses.
