SPF
- EPF - UPF :: Learn the facts about protection factors...
SPF-
rates sunscreen, makeup and lotion. SPF (Sun Protection
Factor) ranges from (2-50+). Without protection, the sun begins
to damage your skin after about five minutes of exposure. An SPF
15 will protect you for about 75 minutes (15 times longer than
you would be without sunscreen).
EPF-
rates sunglasses. EPF (Eye Protection Factor) is used
to rate the protection of sunglasses. An EPF of 10+ = 100% UV
Blockage.
UPF-
rates sun protective clothing. UPF (Ultraviolet Protection
Factor) ranges from 2-50+. This, like SPF, measures how much longer
protected areas can be in the sun without being burned.
