Blue light or blue-violet light can be damaging to delicate retinal cells deep in the eye. Additionally, studies have shown blue light is a risk factor for the onset of age-related macular degeneration, which is a progressive condition that can lead to vision loss over time.
Dangerous Light
Infrared light can emit thermal energy that can harm your body. A microwave, the wavelength of light falls between radio and infrared waves, can heat the water molecules in deep tissues, affecting the body's moisture levels. Plus, gamma rays are the most dangerous because they can warp the body's cells.
Constant exposure to blue light over time could damage retinal cells and cause vision problems such as age-related macular degeneration.
Because of blue light's short wavelength, the focus is not located in the center of the retina but rather in the front of the retina, so that the long exposure time to blue light causes a worsening of visual fatigue and nearsightedness.
Blue light has the strongest impact. Exposure to blue light (and white light, which contains blue light) during the sensitive period can make it difficult for you to fall asleep and stay asleep. Exposure to white light during the day can have positive effects, including boosting alertness and mood.
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.
Yellow light, has been proven effective in protecting the retinas of patients exposed to excessive blue light, since it offers the best contrast.
(Retinal specialists treat conditions affecting the retina, a thin tissue at the back of the eye that is responsible for vision.) Many people ask whether blue light will increase their risk of age-related macular degeneration and blindness. The short answer to this common question is no.
Chronic exposure to LED lights can speed up the ageing of retinal tissue, leading to a decline in visual acuity and an increased risk of eye diseases such as age-related macular degeneration (AMD).
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
Blue is one of the rarest of colors in nature. Even the few animals and plants that appear blue don't actually contain the color. These vibrant blue organisms have developed some unique features that use the physics of light.
Complete heterochromia is definitely rare — fewer than 200,000 Americans have the condition, according to the National Institutes of Health. That's only about six out of every 10,000 people. It's currently unknown how rare central heterochromia is, but we do know that it isn't quite as rare as complete heterochromia.
Vermilion. Both a brilliant red or scarlet pigment, Vermilion was traditionally made from powdered cinnabar, a form of mercury sulfide. Vermillion pigment has been used as far back as 8000 7000 BC.
Red – indicates (1) danger, (2) stop or (3) presence of fire protection equipment.
Psychologists have noted that the impression from color can account for up to 60% of the decision to accept or reject a product or service. Consider that Oranges, Reds and Yellows are considered “exciting” or “alarming” colors while Blues, Purples and Greens are more “calm” colors.
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.
Inversely, exposure to blue light in the hours leading up to bedtime can hinder sleep. Blue light suppresses the body's release of melatonin. View Source , a hormone that makes us feel drowsy. While this promotes wakefulness during the day, it becomes unhelpful at night when we are trying to sleep.
Light from electronic screens comes in all colors, but the blues are the worst. Blue light fools the brain into thinking it's daytime. When that happens, the body stops releasing a sleep hormone called melatonin. Melatonin is nature's way of helping us wind down and prepare for bed.
Therefore, the best color temperature LED for your eyes is anything in the warm white color temperature range (2700-3000K).
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.
1) Green: Concentration
Low wavelength colors promote restfulness and calm, and they improve efficiency and focus. So that's why green is an excellent color for improving concentration.
The worst colors for bedroom lighting are blue and white light. Most of us are no strangers to the dangers of blue light from screen-based electronics. It is well known that exposure to blue light can negatively affect sleep quality. Babies and children are also negatively affected by blue and white light before bed.
Red light, night light. The human eye is less sensitive to longer wavelengths, so red light is chosen to preserve the night vision of the crew while still allowing them to still see their instrument panels.
Because of the lifespan of an LED and its energy-saving capabilities, you'll end up saving a lot of money in the long run. So yes, you can keep LED lights on 24/7. Whether it's Christmas lights or strip lights, LED lights are the best option for prolonged usage.
