What is the blue ray?
- Light is an electromagnetic radiation with wave-particle duality.
- The shorter the wavelength, the higher the energy and the stronger the penetration. (E.g. gamma rays, x-rays, ultraviolet rays Lights, etc.)
Visible light and blue light
Mortality for retinal cells in different wavebands in light condition
Phototoxicity test:
- Light conditions: Simulating the intensity of natural light reaching the retina.
- Illumination Time: 18 hours.
- Comparison of retinal pigment epithelial cell mortality between light and dark environments.
- Experimental conclusion: the most harmful wave bands are focused around 435±20nm.
Where is the blue ray?
Blue ray is everywhere.
- Outside: Sunlight is the main source of the blue ray.
- Inside: LED light, screens of computers, Phones, and other digital equipment can emit plenty of blue rays.
- On rainy days and nights: Plenty of high-energy blue light and visible hard light come from artificial light.
Hazard of blue ray:
Eye Strain
The focus of blue light falls in front of the retina, and it increases chromatic aberration and blurred vision, which will make eye muscles excessively tense. In this way, people will have more eye strain.
Macular Degeneration
High energy blue light can go directly to the retina without any hindrances, which will aggravate the damage to macular area. In particular, it will be more severe and cause more injury to people had cataract surgery before.
Arsing Glare
When the high-energy blue light meets the tiny particles in the air, It will be more easier to scatter. —–So it will arsing glare, and decreasing the visual contrast.
Eye Strain
Receiving too much blue light before sleep (such as reading novels, playing games,etc.) can inhibit melatonin secretion, and disrupt the circadian rhythm which may lead to night insomnia and daytime fatigue.
Benefits of blue light:
Regulating circadian rhythm.
Stay active during day.
Improve Mood.
Improve memory.
Prevention of myopia in children.
Affect night vision.
