Yellow light, has been proven effective in protecting the retinas of patients exposed to excessive blue light, since it offers the best contrast.
Therefore, the best color temperature LED for your eyes is anything in the warm white color temperature range (2700-3000K). Since clarity and contrast is a big part of lessening eye strain, a color-corrected type like our warm white Chromalux® LED might also be a great option!
Yellow light has been shown to be effective in protecting the retinas of patients with overexposure to blue light because it produces the best contrast. Sunglasses with yellow lenses are quite effective not only at filtering ultraviolet rays but also blue light.
Purchase 'warm white' LED lights: The ANSES report also recommends using LED lights that are 'warm white' rather than 'cool white', as these lights emit less blue light which in turn reduces the potential damage to your eye health.
Choose a bulb with a color temperature of 2700K or lower, preferably 2400K. These bulbs are usually labelled "warm white" but confirming the exact color temperature can be preferable.
The ANSES report shows that exposure to blue light can cause permanent damage to the retina. Light-induced retinal damage can result from viewing either a very bright light for a short time (acute exposure) or a less bright light for a longer duration (development of Age-Related Macular Degeneration – AMD).
Red light therapy is generally considered safe, even though researchers aren't exactly sure how and why it works. And there are no set rules on how much light to use. Too much light may damage skin tissue, but too little might not work as well.
Conclusion: Red Light Helps Protect and Heal Your Eyes. Red light therapy treatments, with both red and near infrared wavelengths, aren't just safe for eyes. They're also a proven way to help heal eye injuries, reduce inflammation, and protect against vision loss, as shown in numerous peer-reviewed clinical studies.
Exposure to white light during the day can have positive effects, including boosting alertness and mood. Red light has no effect on the circadian clock, so you can use a dim red light at night. Yellow and orange light have little effect on the clock so you can use a very dim yellow or orange light at night.
When it comes to color combinations, your eyes prefer black text on a white or slightly yellow background. Other dark-on-light combinations work fine for most people. Avoid low contrast text/background color schemes. If you wear contacts, your eyes have to work harder when staring at a screen.
Warm light is best for the eyes. This includes filtered natural light and light produced by incandescent and LED light bulbs. Spread out lighting in your home and workspace to ensure sufficient lighting.
A high color temperature is connected to optimal studying performance and focus. Cool white light is the best LED light color for studying.
It has been shown that our eyes react to the blue light, telling our circadian rhythm to “stay awake”. Similar to the sunlight, blue light signals our brain that it's time to get going. This means that using LED excessively, especially at nighttime can cause eye strain and influence your sleep.
We suggest using incandescent or halogen bulbs throughout the day + night if you're after a greater sense of well-being. Also - unlike most harshly flickering LED or fluorescent bulbs - incandescents (and color-correct halogens like Chromalux®) will also be the healthiest type of light for your eyes!
Blue light is one of the highest intensity types of visible light with very short wavelengths that produce a high amount of energy. Blue light is the most damaging light to our eyes in the visible light spectrum.
1. Blue light. According to a 2017 study in the scientific journal PLOS ONE (9), blue lighting “accelerates the relaxation process after stress in comparison with conventional white lighting.” This study found that stressed people immersed in blue light relaxed three times as quickly as in white light.
This effect is called chromostereopsis. The effect is strongest with red and blue, but it can also happen with other colors, for example, red and green. These color combinations can be hard and tiring to look at or read.
Some studies show blue light can cause retina damage because of this. This is called phototoxicity and its impact completely depends on the length of exposure and intensity of light. These LEDs are linked to digital eye strain, dry or irritable eyes, and blurred vision.
High-intensity blue light from any source is potentially hazardous to the eye. Industry sources of blue light are purposely filtered or shielded to protect users. However, it may be harmful to look directly at many high-power consumer LEDs simply because they are very bright.
So, how can I protect my vision from LED exposure? The ANSES report recommends buying “warm white” LED home lighting, limiting your exposure to LED sources with a high concentration of blue light, and avoiding LED screens before bedtime.
It is an interesting trait that deep red lights do not trigger the neutralization of the rhodopsin, so astronomers and safety officials use red lights for night lighting to allow night vision to continue.
Using a red light night light not only helps your child stay asleep, but it also eliminates the chance for your child to wake up and become fearful of the dark. If you find your child waking up, especially from night terrors or with a fear of the dark, red light therapy may be beneficial to your child.
Research studies discovered red to be the best color light to help you sleep, because it increases production of melatonin as well as full darkness. On the other end of the spectrum, blue is the worst. Despite being a calm-inducing color on most occasions, blue is not suitable for lighting a bedroom.
In studies of LED lighting, blue light exposure was shown to cause the pupils to constrict and lead to ocular deficiencies like blurry and double vision. It can also lead to temporary sensitivity to light for a healthy person and enhanced photophobia for an already-sensitive individual.
