Can
you believe it’s the end of June already? It seems like only yesterday that we
were observing Memorial Day and before that, bundling up from the freezing
winter season. (Our friends on the East Coast can tell us Californians
something about that!) Now that the sun is out and the temperatures are more
pleasant, you will inevitably be spending more time outside. But when you are
outside, make sure to have the usual protection: sunscreen, a hat…and
sunglasses.
Make
sure to check the UV Index if you know that you’re going to be outside a lot. Understanding
the UV
Index Scale
can be tricky. One good tip is to check your shadow. If your shadow is taller
than you are, the UV Index is most likely low. If your shadow is shorter than
you are, you are most likely experiencing a higher UV Index. This is common
between midday (10am-4pm). Once the UV Index jumps over level 5, it is time to
take extra precautions to protect against the damaging and harmful rays that
can cause sunburn.
It
is also important to wear sunglasses that will protect your eyes against UVA and
UVB rays from the sun. One of the easiest ways is to pick
glasses with a sticker that says something along the lines of:
- Blocks 99%-100% of UVB and UVA rays
- Lenses meet ANSI Z80.3 blocking requirements
- UV 400 protection (this means they block light rays with wavelengths of up to 400 nanometers)
Since
the UV blocking coating is clear, it doesn’t necessarily matter whether or not
you get dark or lighter tinted lenses. One thing to keep in mind though is that
rose- or yellow-tinted lenses can make it difficult to distinguish between
changing traffic lights. This is why green, gray or brown lenses are better for
driving, as they
minimize color distortion.
If
you spend a lot of time on or near the water, opt for polarized lenses.
Polarized lenses reduce glare by filtering out the reflected light that bounces
off of surfaces such as water or the pavement. If you should choose to purchase
a pair of polarized lenses, remember this: polarization has nothing to do with
UV filtering. If you are purchasing
polarized lenses, make sure they also provide full protection against
ultraviolet light.
If
you are buying your first pair of sunglasses,
make sure to consult the professionals at Site for Sore Eyes. They can help you select a pair
that will fit your prescription and are in accordance with UV blocking
regulations. They can even give you more information on how to protect your
eyes on days when the sun is up and the UV rays are particularly strong.
