Nowadays,
anti-blue glasses have become most people’s first choice. We all know that
anti-blue glasses can protect our eyes from harmful light from computers,
cellphones and some other digital products. But do you know how to pick a pair
of suitable anti-blue glasses correctly?
And today we’ll
offer some common things and tips on choosing a pair of anti-blue glasses. OK,
let’s start!
What are
anti-blue glasses?
S7715
In simple terms,
harmful blue light refers to light with a relatively high energy between 400nm
and 480nm. The blue light in this wavelength will increase the amount of toxin
in the macular area of the
eye, which threatens our eyes. Anti-blue glasses, in short, are glasses that
can block the damage of blue light to the eyes, and the blocking methods
include coating radiation and molecular absorption filtration.
How to choose anti-blue glasses?
Price
 |
| S5616X |
When we choose
anti-blue glasses, we should recognize that the price of anti-blue glasses is
different, the lowest is only a dozen dollars, and the highest can reach
thousands of dollars. Due to the difference in price, the actual anti-blue
light effect also has a big difference. It is recommended that consumers should
view their basic data information, and do not buy inferior products because they are cheap.
Three Data
 |
| S1420 |
In general, the
three most important data for anti-blue glasses lenses are anti-blue light
rate, light transmittance, and chromatic aberration. Among them, the anti-blue
light rate generally needs to be above 35%, the light transmittance needs to be
maintained above 90%, and the color difference is as low as possible.
It should be
noted that consumers should not excessively pursue the anti-blue light rate, and
sacrifice the light transmittance and chromatic aberration. Such products tend
to have a greater burden on the eyes, but they will be counterproductive. In
addition, some users prefer to select some products with yellow lenses, but the
anti-blue light rate of such products is not necessarily excellent, and the
specific anti-blue-ray rate should be based on the product description.
Qualification Certificate
View the
qualification certificate on some e-commerce websites, the price of anti-blue
glasses is often very low, and the publicity page is also very long. However,
there is no mention of the qualification certificate of the product. Therefore,
in addition to viewing the basic data information, consumers should also pay
more attention to the qualification test. Good anti-blue-ray glasses often have
the qualification certificate of supervision by domestic and foreign
authorities, while the low workshop products do not have such information. When
we actually purchase, we can also check whether the product promotion page
contains such qualification information. It is recommended to select products
with qualified information and the quality is more secure.
Weight and Colors
In general,
anti-blue glasses are mostly designed
How long to wear them?
In addition,
anti-blue glasses should be used reasonably, and wearing them for a long time
will cause damage to the visual resolution, especially those with high
anti-blue light rate.
What else can protect from blue ray?
In addition to
anti-Blu-ray glasses, we can also choose anti-Blu-ray mobile phone film,
anti-Blu-ray computer film and other products, multi-pronged, to minimize
harmful blue light damage, create a more comfortable eye experience.
