Are you fully protected?

I recently blogged about sunscreen; that your skin should be protected not only in the summer but all year round and ensure that your skin has optimum protection from the sun (Click to read this blog).
I just read an article/questionnaire on the Boots website on "Dangerous UV Rays" and I got 2 questions wrong. I thought it is has some really good facts so wanted to share it with you guys. I've copied and pasted my results below.

Results: Dangerous UV rays: Are you fully protected?

You answered 6 out of 8 questions correctly. Your quiz results:

1. Sunscreen and sunglasses are most important in summer, when ultraviolet (UV) rays are intense.
   
   

   You answered: True

   The correct answer is: False
   The sun produces visible and invisible light. Exposure to the invisible kind, ultraviolet A and ultraviolet B (UVA and UVB), is never safe and is responsible for skin cancers, cataracts, sunburn and premature ageing. That's why it's important to limit exposure to UV rays all year. While UV ray intensity tends to be highest in the summer, experts say there is no "safe" UV exposure. UV radiation can damage the body any time of year, even when it's cloudy.
   The answer? For adults and children over six months old, experts recommend sunglasses and a generous application of sunscreen with a UVA and UVB sun protection factor (SPF) of at least 15.
2. The darker your skin, the less you have to worry about UV rays.
   
   

   You answered: False

   The correct answer is: False
   It's true that darker skin doesn't burn as easily as lighter skin, but UV rays can lead to lasting harm, melanoma cancer, eye cataracts and other problems, no matter what your skin tone is. Research shows that cataracts are more common in black people than in white people. Also, skin cancers in people with darker skin are often not detected until later stages, when they're more dangerous.
3. For UV protection, even waterproof sunscreen must be reapplied after swimming.
   
   

   You answered: True

   The correct answer is: True
   A sunscreen needs to maintain its SPF after 80 minutes of exposure to water to be considered waterproof, yet even waterproof sunscreens can rub off. To stay safe, apply at least an SPF15 sunscreen 30 minutes before going into the water, and then again after you come out.
   Did you know sunscreens have a use by date? Like lots of products, sunscreen can become less effective over time. Check the label on yours, it may be time for a new bottle.
4. Wearing a hat is the best UV protection for your eyes.
   
   

   You answered: False

   The correct answer is: False
   UV rays can severely damage eyes and the exposure accumulates, leading, for some, to macular degeneration, cataracts and blindness later in life. While a wide-brimmed hat offers good protection from ultraviolet light, it still manages to block only some of the sun's rays. The best protection from damaging UV rays comes from sunglasses that filter out 99% to 100% of ultraviolet light.
5. Sunglasses are recommended for adults and teenagers, not children under 12.
   
   

   You answered: False

   The correct answer is: False
   Children usually spend a lot more time outdoors in the sun than adults, and that means they're potentially exposed to a lot more UV rays. The risk for retinal damage is greatest for children under 10, says Dr Alan Greene, clinical professor of paediatrics at Stanford University School of Medicine in the US. That means sunglasses are a vital part of every child's sun protection, no matter what their age.
6. Damage from UV rays, like sunburn, heals after a couple of weeks.
   
   

   You answered: False

   The correct answer is: False
   We suffer temporary pain with sunburn, but most effects of sun damage add up over our lifetime and can lead to life-threatening problems like skin cancer, macular degeneration and cataracts, as well as premature ageing. It is worth remembering that there is no safe level of UV exposure and no "safe" tan either.
7. Snow reflects over four times as many UV rays as sand and water.
   
   

   You answered: True

   The correct answer is: True
   Snow is an excellent reflector, sending 80% of the sun's rays back to us, sand and water reflect less than 20%, that's why it pays to be protected all year, even in winter. Wear sunscreen, sunglasses and protective clothes whether you're playing on the beach or skiing on the slopes.
8. All sunglasses protect against both UVA and UVB rays.
   
   

   You answered: True

   The correct answer is: False
   You can actually get sunburn on your eyes, raising your risk of macular degeneration and cataracts later in life. The best way to protect your vision is with sunglasses. But be careful when buying them; not all sunglasses filter out the same amount of sun.
   Expensive lenses or those with a dark tint don't guarantee more protection than cheaper, lighter lenses. So always read the labels. Look for sunglasses that block 99% to 100% of UVA and UVB rays, say the experts and look for snug-fitting glasses with large lenses, preferably with a wraparound design. These features all help to block damaging UV rays.
