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.
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!
Constant exposure to blue light over time could damage retinal cells and cause vision problems such as age-related macular degeneration.
As with any type of light, it is important to be mindful of exposure and take steps to protect your eyes from excessive exposure to bright light, such as wearing sunglasses or reducing screen time. Ultimately, the idea that green light is inherently harmful to the eyes appears to be a myth..
The consensus is that the "non-colours", white and black, and the colours yellow, green, and orange are generally most acceptable. These colours (yellow, green, orange) are in the middle of the visible spectrum (the range of colours that our eyes can detect) and are the easiest for the eye to see.
Advantages: Comfortable for the eyes: Yellow light is gentle on the eyes, which can help alleviate eye strain and fatigue during long study sessions. Enhances relaxation: The warm ambience created by yellow light can make the study environment feel more inviting and calm, potentially improving concentration.
While LED lights themselves are not necessarily bad for our eyes, prolonged exposure to the blue light they emit can cause eye strain, headaches, and other negative effects on our vision. This can be particularly problematic when we spend a lot of time using screens or under bright, fluorescent lights.
Red light treatments improve the effects of glaucoma and prevent vision loss by protecting the cornea and retina, especially against the ocular pressure and fluid buildup, which is one of the main complications that occurs with glaucoma cases.
Looking into a deep red light for 3 minutes each day may significantly improve declining eyesight, according to a study published in Journals of Gerontology. Looking into a deep red light for 3 minutes each day may significantly improve declining eyesight, according to a study published in Journals of Gerontology.
Blue light, or high-energy visible (HEV) light, has a longer wavelength than UV light, at around 450 to 490 nanometers. The sun emits blue light alongside UV rays. However, blue light penetrates deeper into the ocean than UV light.
It is generally considered that red breaks down rhodopsin more slowly and, if preserving night vision is the main objective, red is better. But green light penetrates a little better, and shows more detail. It may be preferred for distance vision, and for close up clarity, such as reading instruments or maps.
A study published in SLEEP journal6 compared people's performance and sleepiness exposed to blue light at 460nm or green light at 555nm during the day, to the same levels of exposure at night. The results showed across the board that blue light caused higher ratings in measures of alertness than green light.
For instance, red shades tend to trigger your stress response, making you more anxious, while lighter shades calm you down. If you are feeling overly stressed, you can use color as a stress management tool.
The Color of the Light Affects the Circadian RhythmsBlue light has the strongest impact.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 light, has been proven effective in protecting the retinas of patients exposed to excessive blue light, since it offers the best contrast. Sunglasses with yellow lenses can be very effective in filtering out not only UV but blue light too.
Nature white 4000–4500K or daylight white 6000–6500K is the best LED light color for studying. You can focus on your task easier under a white color lamp. Though your eyes may feel comfortable with warm yellow light, you will be sleepy during studying.
In a study by the Lighting Research Center, participants who read under warm white LEDs scored an average of 5% higher on reading comprehension tests than those who read under cool white LEDs. That's a significant difference that could mean acing an exam or barely passing.
Correlated color temperature (CCT) defines how blue or yellow the light color is. It's measured using the Kelvin temperature scale and ranges between 1500 and 6500 Kelvin. A high color temperature is connected to optimal studying performance and focus. Cool white light is the best LED light color for studying.
Red light has no effect on the circadian clock, so you can use a dim red light at night.
Blue light is of concern because it has more energy per photon of light than other colors in the visible spectrum, i.e. green or red light. Blue light, at high enough doses, is therefore more likely to cause damage when absorbed by various cells in our body.
Wavelengths of both red light (in the mid-600nm range) and near infrared light (in the mid-800nm range) have been tested in multiple clinical trials and found to be safe and effective for ocular health and vision protection.
Harmful effects of ultraviolet (UV) and blue-violet light manifest differently in the human eye. Cumulative exposure to blue-violet light has been linked with the development of age-related macular degeneration (AMD).
“[Blue light] is thought to penetrate deeper into the skin than UV light but fortunately is not associated with the development of skin cancer,” adds Joshua Zeichner, MD, the director of cosmetic and clinical research in the dermatology department at Mount Sinai Hospital's Department of Dermatology in New York City.
