You may feel that wearing normal clothing can protect you from the sun UV radiation; but this is not true. Not all sunscreens provide the same sun protection (sunscreen UV protection is measured in SPF – Sun Protection Factor), and not all sunglasses provide the same eye protection (eye UV protection is measured in EPF – Eye Protection Factor); the same applies to clothing which is measured in UPF – Ultraviolet Protection Factor.
Therefore, it is very important to make sure the type of clothing or
swimwear you use on the beach have been tested and certified to offer
the highest UPF rating of UPF50+ (blocks >97.5% of the sun UV
radiation). You can find sun protection clothing and swimwear products
online from several suppliers; however only few have the right
certification or their fabric have been tested for protection against UV
radiation.
