Hi dear ones,

Bring something cool , DUDE !!

 

Why do I  need to wear sunglasses?

 The sun has damaging UV rays that can cause photokeratitis, pingueculae and permanent retinal damage.

Ultraviolet (UV) rays are located just past the violet portion of the visible light spectrum; sunlight is the main source. UV light is broken into three different types: UVA, UVB and UVC. UVA has longer wavelengths and passes through glass easily; experts disagree about whether or not UVA damages the eyes. UVB rays are the most dangerous, making sunglasses and sunscreen a must; they don’t go through glass. UVC rays do not reach the Earth because its atmosphere blocks them.

Most people think that they’re at risk only when they’re outside on a sunny day, but UV light can go right through clouds, so it doesn’t matter if the sky is overcast. The sun’s rays are strongest between 10 am and 2 pm.

Glare and reflections can give you trouble, so have your sunglasses ready if you’ll be around Dust, water, hot breeze and sand, or if you’ll be driving (windshields are a big glare source).

The following put you at additional risk: sunlamps, tanning beds and parlors, photosensitizing drugs, and living at high altitudes or near the equator.

Relationship between UV Index and UV Exposure Category
UV Index Exposure Category
2 or less Low
3 to 5 Moderate
6 to 7 High
8 to 10 Very High
11+ Extreme

UV Index
 
The UV Index is a forecast of the amount of skin damaging UV radiation expected to reach the earth’s surface at the time when the sun is highest in the sky (around midday). The amount of UV radiation reaching the surface is primarily related to the elevation of the sun in the sky, the amount of ozone in the stratosphere, and the amounts of cloud cover. However, thick cloud can greatly reduce ultraviolet radiation levels and, surprisingly, certain types of thin cloud can magnify the ultraviolet radiation strength.

The higher the UV Index, the greater the dose rate of skin damaging (and eye damaging) UV radiation. Consequently, the higher the UV Index, the smaller the time it takes before skin or eye damage occurs. Find out about your risk and burning time with our skin type table 

Risk of damage to skin
UV INDEX SKIN TYPE
  white (burners) white (tanners) naturally brown naturally black
         
  low no risk no risk no risk
  low no risk no risk no risk
  medium low no risk no risk
  medium low no risk no risk
  high medium low no risk
  high medium medium low
  very high high medium medium
  very high high medium medium
  very high high medium medium
  very high high high medium

 Low risk means that there is nothing to worry about – the sun will not harm you. Redness (erythema) will appear in 2 hours or more.

Medium risk means that the sun is not dangerous, but you should avoid being in direct sunlight for more than 1 to 2 hours. Redness (erythema) will after longer exposition. Burners should apply skin protection factor (SPF) 15 sun screen. All people should wear UV-A+B sun glasses

 High risk means you could burn in 30 to 60 minutes. Try to keep out of direct sunlight, cover up or wear a sunscreen lotion SPF 15+. Use protective clothing.

 Very high risk means that you could burn severely in 20 to 30 minutes. Stay out of direct sunlight, cover up and use a sunscreen lotion SPF 15+.

 People of all skin colour, especially children and babies, can suffer eye damage, over heating and dehydration as a result of excessive sun exposure.

BE WISE , CHOSE NICE for the EYES !!!

Goggles !!!!

Step 1

Check labels to make sure the sunglasses provide 100 percent UVA and UVB protection.

Step 2

Look for sunglasses that filter out at least some blue light, which can damage the retina and lead to macular degeneration (vision loss from degeneration in parts of the eye). To make sure, try wearing them outside; a blue sky should appear gray with these on. Also ask about polarization, a type of filtering that helps reduce glare.

Step 3

Choose a lens color based on your preferences and comfort level. Gray doesn’t affect color perception; orange-brown lenses are a good choice for those with macular degeneration, since they filter out UV and blue light rays for maximum retinal protection; green lenses distort color less than other shades, such as red or yellow.

Step 4

Opt for lightweight, plastic, shatterproof sunglasses if you’re going to be wearing them when playing sports.

Step 5

Purchase sun goggles for total protection of your eyes. These cover a large area and include side shields. As an added bonus, they also fit over prescription glasses.

 Tips & Warnings

  • A darker lens does not necessarily indicate better protection, and lighter-tinted lenses offer better visibility. Check labels to find sunglasses that provide the best protection possible.
  • To ensure against mislabeling, you may want to purchase a UV card, a credit card’ size device for testing sunglasses.
  • For added eye protection, wear a hat with at least a 3-inch brim.
