What makes your eyes “ill”?
The specific reasons are as follows:
1. Bad eye environment
- Too strong or too weak lighting can easily cause visual fatigue
- Too much light can irritate the eyes and make it difficult to read the text
- Too weak light will cause pupil dilation and increase eye burden
- The light is uneven, and the pupils will be different because of the difference in brightness.
- Constantly adjusted to the light, increasing eye fatigue
2. Eye use is too long, too close
Eye survey according to bad habits shows
80% of people in US staring at the screen for more than 4 hours a day.About a third of people
use electronics for more than 8 hours a day.Office worker, student party are heavy users of electronics staring at a close distance for a long time can cause excessive strain on the eye muscles prone to symptoms such as dizziness, blurred vision, headache, and nausea.
3. Fewer blinks
Normal situation, a person blinks about 20 times a minute.But when using a phone / tablet, too focused due to the small screen, significantly fewer blinks per minute.Tear film rupture time shortened, resulting in insufficient secretion of tear fluid prone to dry eye.
Do these things scientifically
It is obviously unrealistic for modern people to want to completely abandon electronics
To protect your eyes, start with these points:
1. Proper use of electronics
- The distance between the eyes and the screen is above 50CM
- Sight 15-20CM above the center of the screen
- Adjust font size to make text easier to see
- Adjust display brightness for comfortable reading without glare
- Minimize use time
2. Choose the right fixture
Never turn off the lights to see electronics! !!
Can be equipped with a table lamp to reduce light intensity error
Optimize the eye environment
For table lamps, there are clear standards
- Color temperature should not exceed 4000K
- The retinal blue light hazard group of the reading and writing desk lamp cannot exceed RG0
- Illumination of at least 500lx in the central area and 250lx at the edges
- Therefore, it is best to choose LOHASLED E26 light bulb for work and study
3. Blink more
Guaranteed to blink at least 15 times per minute
Keep tear film fully moist
4. Follow the 20-20-20 principle
20-20-20 principle
Advice from the American Academy of Ophthalmology (AAO)
Look up 20 feet (about 6 meters) every 20 minutes for at least 20 seconds
5. Use correct posture
The eye is about an arm away from the screen
Screen is slightly below sight
Sitting upright without leaning forward or hump
Eyes are our window into the world
If something goes wrong with this window
The world will also be blurred and lost
Everyone must protect your eyes and use your eyes healthily
Make the world you see clear
