question 1: does the film really hurt your eyes
Answer: it really hurts my eyes.
Cell phone lamination will certainly reduce the transparency of the screen, whether it is a toughened film with a permeability of 98% or a high-definition film with a permeability of 93%. In addition, some films are of poor quality, which will lead to scratches after use, which will further reduce the transparency.
Then, the clarity of the screen will decrease, which will increase the fatigue of the eyes. Over a long period of time, it will cost more eyes and harm your eyesight.
question 2: is the eye injury caused by the film serious
Answer: no mobile phone is seriously injured.
In fact, the mobile phone film is not a direct factor affecting the eyes. The display, brightness, luminosity, etc. of the mobile phone will stimulate the eyes if you look at it closely for a long time.
Ophthalmologists explained that when focusing on the mobile phone screen, the constantly changing lights and shadows on the screen will cause continuous irritation to the eyes. When the eyes keep capturing these lights and shadows, it will damage the tear film layer on the surface of the black eyeball, which will aggravate the fatigue, dryness, itching and other feelings of the eyes, and even make the eyes have uncomfortable symptoms such as stinging, tears and photophobia.
question 3: can I apply a film
Answer: this question is ultimately up to you.
The film does damage your eyes, but the damage to your eyes caused by the film is far less than the damage to your eyes caused by the mobile phone itself, so if you can insist on playing your mobile phone for one hour less every day, I think this is enough to make up for the damage to your eyes caused by the film.
In many articles, experts agree that the screen will not be scratched, so there is no need to apply a film. As a responsible editor, I just want to ask you: is the film to avoid being scratched? You’re worried about being broken, okay? Therefore, if you are not a local tyrant, I suggest you stick a film.
the following tips can alleviate the damage to eyes caused by mobile phone mask
1. Don’t buy those marked with transmittance above 97%
Many mobile phone stickers will be labeled with “99% light transmittance” on the package, but experiments have proved that this number deceives consumers. Because the optical glass with the highest transmittance has a transmittance of about 97%, the mobile phone protective film can’t reach the transmittance of optical glass at all, so it can’t reach “99%”. When you see that there is a mobile phone sticker with a light transmittance of more than 97% on the package, you should not buy it. This number is false.
2. Change the mobile phone film frequently
One of the reasons why the mobile phone film damages the eyes is that there are many scratches on the mobile phone film used for a long time, which affects the light transmittance and thus causes visual fatigue. Therefore, to reduce the damage to the eyes caused by the mobile phone film, it is necessary to replace the mobile phone film frequently, so as to prevent eye fatigue and myopia from being aggravated due to too many scratches.
3. If there are bubbles in the mobile phone film, paste it again
Because the bubbles on the mobile phone film can’t clearly see the words or patterns displayed on the screen, which will hurt your eyes, you should re paste the bubbles on the mobile phone film to avoid visual fatigue.
4. Do not buy luminous film
The noctilucent cell phone stickers that are popular in the market now also do a lot of harm to the skin, because many noctilucent cell phone stickers actually add fluorescent powder to ordinary stickers. Generally, noctilucent cell phone stickers do not contain radioactive substances, but they are mixed with fluorescent powder. When using noctilucent cell phone stickers, they are usually very close to the respiratory tract of the human body, which is easy to inhale, and long-term contact is harmful to the skin and human body.
5. Reduce the time spent using mobile phones
The world is very beautiful. Why not go out and go downstairs!
