The UV Card is perfect for all those who tend to scurry under the shade whenever the sun gets too strong for them, which isn’t a bad thing considering you have forgotten to put some sunblock on. Anyways, the more scientifically minded who love taking details of their environment will find the UV card to come in handy as it will be able to indicate the current UV intensity within three seconds, displaying it in three levels (1 to 3 indicates low, 4 to 6 is middle while 7 to 8 means staying indoors and wait till dusk). The UV Card retails for $11.50.
