Yellow light is the best contrast against blue light and can protect the retinas of the eyes. Whatever color you choose to use during the day, it's essential not to overexpose your eyes to any light source. Other colored lights that can have an effect on the eyes include green, red, and yellow lights. Green lights can help regulate the circadian rhythm.
Overexposure to green light during the night, such as blue light, can reset the clock and alter the natural rhythm. Yellow light has been shown to be useful in protecting the retinas of patients exposed to extreme blue light, as it offers the best contrast. Sunglasses with yellow lenses can be very powerful at filtering not only UV rays but also blue light. The lens of the eye naturally acquires a yellowish tint with age, to help filter blue light.
Warm light is best for the eyes. This includes filtered natural light and light produced by incandescent and LED bulbs. Blue light filters are no less than a blessing for someone whose working nature requires excessive screen use. One of the most commonly used blue light filters is Iris.
You should consider a few different factors when choosing the best color light for reading and studying. The amber light and red light of blue light blocking bulbs are the best colored lights for reading and studying at night because they do not affect the circadian rhythm or alter the hormonal balance. For eye health, the best types of lighting for living and working include warm light sources, such as natural light. It is important to ensure that your blue light glasses are manufactured by a reputable brand that has researched the requirements for effective blue light glasses to ensure that your eyes are properly protected.
Generally, looking at Kelvin ratings can help you determine the type or color of the light produced by the bulb. Reducing the use of cell phones, tablets and laptops just before bedtime should also help minimize the negative effects of blue light that. The wavelengths of blue light emitted by LED lights can alter hormonal balance, sleep pattern, and other natural biological functions by preventing the natural increase in melatonin that should occur at night. And potential long-term damage or eye disease from certain types of wavelengths of light are also risky.
Studies have also been conducted that claim possible damage to the retina from prolonged exposure to digital blue light. The type of light you use and are exposed to most often affects not only the environment, but also your eye health. Delayed melatonin production due to exposure to blue light could cause even more problems than insomnia, such as blood pressure, diabetes and migraines, while generating considerable retinal stress and toxicity. Exposure to ultraviolet light can cause cataracts and blindness, warns the American Optometry Association (AOA).
The blue light produced by televisions, smartphones, tablets and computers is a form of cold light that can be harmful to the eyes in high and prolonged doses.
