Our eyes are said to be the window of the
soul, through which we are able to understand the world and make researches,
but sometimes we also need the curtains for them. When the sunlight is very
scorching outside, it is far from enough for you to apply sunscreen only.
According to a study
conducted in the United States, 79% of people have known that long-term
exposure to sunlight is likely to cause skin cancer, but only 6% of the people
realized that ultraviolet rays do great harms to eyes, especially in summer
when the omnipresent UV eyes will bring injuries to people’s eyes. At this
time, putting on a pair of sunglasses can not only protect your eyes, but also
make you more stylish! Besides, for those who have strong desire of
self-expression, the dark glasses are representative techniques of a kind of
fashion statement and individualism.
As for the selection
of sunglasses, you have some general rules t follow.
First, the lens colors that have a protective
effect to people’s eyes are brown, dark green, gray, because this type of
colors can be effective in filtering strong lights and will not cause any visual
identification of the color error. In general, the lens with both too deep and
too shallow colors does no good to the eyes at all. On one hand, too deep color
is more likely to cause dilated pupils, which, as a result will otherwise make
eyes absorb more and more UV rays; on the other hand, too shallow color cannot
filter the main light at all, let alone the anti-UVA and UVB functions, so the
protection of eyes at this time is almost equal to zero.
In addition, when in choice of colored
lenses, you are recommended to base on your own skin color. To those in white
skin, a variety of bright colorful lenses are suitable; to those yellow ones,
it is recommended to choose the natural, earth tones and so on, such as
champagne color or pink orange color; while the dark complexion people had
better choose the color in strong contrast, like pink, mustard green color,
which looks healthy.
The tips mentioned above are presented for
your reference when you select the sunglasses in this hot summer.
