The summer has arrived. It is time for us to be well equipped to be anti bright sunshine. Otherwise,the consequence of the harm by UV is very serious. Next, I would like to share some sunblock knowledge with you:

• The skin: apply the sunscreen every 2 hours.Long-peaked caps which are able to hide face, neck and ears at the same time should be the best protection from ultraviolet radiation.
• Eyes also need protection from UV as skin. The best anti-UV tool for eyes belongs to anti-UV glasses online which would also make ones be cooler.
• For sun protection, it is healthier, more effective and convenient to wear clothing rather than applying sunscreen.
• About time: Avoid to go outside in 10 AM to 2 PM when the ultraviolet is the sharpest in the whole day.

It is quite easy to be in compliance with these advices. but you may have some difficulty in choosing sunscreen and eyeglasses. Here are some misunderstanding about the two points, please pay attention.

• Some people think that the effect of sunscreen with SPF30 is the double of that of sunscreen with SPF 15, which is wrong. That is wrong. But it is true that the sunscreen with SPF30 is more effective in rejecting ultraviolet radiation.
• In the choice of glasses, people must advert that not colored lenses are sunglasses, and the key is whether they have UV logos.
