Are Neon LED Signs Safe for Your Eyes? Here’s What You Should Know

Neon signs are so striking and bright, you can’t help looking at them. It is always a bad idea to have too many positives. The sun, CFL (Compact Fluorescent Lighting), or neon signs are all harmful to your eyes.
They are safe for the eyes and produce no blue light. They produce negligible amounts of blue light between 400-490nm (nanometers strong>).

The rest of this article will discuss topics related. These include which type of light is most harmful, which neon LED works best for our eyes, as well as the impact of LED on your eyes.

Which lights can harm our eyes?

According to a study “2000-3500 K and greater than 500 nm range of lights is safe.”

Blue light from the visible range can cause eye damage. The two main types of blue light are short-wave and longer-wave.

The short-wave light of 415 nm to 455nm may irritate. In a thorough study in 2018, Researchers found that short-wave light blue may cause dry eyes, disrupt the sleep cycle, and even lead to dry eyes.

Longer wavelengths of light, like 455-495 nm, do not cause any eye irritation. These longer-wavelength blue lights can be used to regulate the sleep cycle.

Warm white LED vs. cold white LED

Warm White LED is capable of producing around 3000 Kelvin Deg (3000K) of temperature. Warm white is closest to traditional incandescent bulbs (or your old, traditional light bulb). It produces a gentler light, which is ideal for most home settings.

The temperature color of cold white LED is between 5000-6000 Kelvin Degrees (5000-6000K) Use cold white LED in the bathroom, kitchen, and other areas.

To produce white light, most LED lamps nowadays use a blue led coated with a pigment. A wavelength of around 470nm LED does not contain UVA or UVB wavelengths that could be harmful.

How do our eyes perceive visible light

All parts of your eyes work together to help you see.

First, light passes by the cornea, the transparent front layer of our eyes. The cornea, which is shaped like a dome, bends light to help the eye focus.

A pupil is an opening that allows some light to enter the eye. The pupil allows light in through an opening called the iris. It is the colored portion of the eye.

Next, light is passed through the lens (a clear inner portion of the eye). The lens and the cornea work together to focus light on the retina.

A retina is a light-sensitive layer of tissue located behind the eye. The retina contains special cells known as photoreceptors. Photoreceptors can trigger electrical signals when they detect sunlight. The signals are sent from rods and cones via nerves that reach inside the brain.

These electrical signals travel from your retina through the optic neuro to the brain. The brain converts the signals to create the images you see.

Which neon light bulb color is best?

The new generation of light sources, neon LED sign, is well-known. Neon LED signs can be used for everything from office decorations to announcement signs to celebration signs. You can use neon LED lights to create almost any color in the visible spectrum.

Yellow color neon LED is the best color for your eyes. Yellow neon LEDs are longer in wavelength and therefore easier to see. It is easily observable.

It is best to not expose our eyes too much to any color. Dimmable neon LED lighting has several benefits. This feature allows you to adjust the intensity of the light so that your eyes are protected and the strain is reduced.

How do you protect your eyes from UV rays?

UV rays exist in every form of light, including the sun and our phones. You can take steps to reduce the effects of UV rays on your eyesight.

Take a break

Limiting exposure is the best way of limiting light exposure. You should take frequent breaks from the computer screen. You can also refer to the 20-20-20 principle.

For 20 minutes, you should take a break and look at something 20ft away for 20 seconds. This technique can help reduce eye strain. It is also a reminder to stay safe from UV light.

Look into computer glasses

If you spend a lot on your computer screens, invest in a pair. Computer glasses come with yellow-tinted lenses which block harmful ultraviolet rays.

You can also purchase glasses that are specific to your work distance. These glasses can relax the eyes and reduce eye strain.

Invest in no-glare lenses

It is a good idea to invest in no-glare contacts if you work at night. The effects of night-time on color recognition and peripheral vision as well as depth perception are all affected by the darkness.

Driving at night is safer and easier with the no-glare lenses. These lenses can help you see clearly and protect your eyes from distracting reflections. It can also relieve eye fatigue.


There are also options for medical treatment that may help to prevent damage to the eyesight. Experts recommend supplements containing vitamins C, and E, zinc, lutein, and zeaxanthin.

Premixed vitamin E was 25% less likely for people to develop eye disease.

LED’s impact on your eyes

Researchers are now concerned by the long-term effects of exposure to LED lights. AMD (Age-related Macular Degeneration) is the leading cause of blindness in the west.

However, a study showed that LED does not pose a risk to the health of healthy individuals. The sleep cycle can be disrupted if you are exposed to too much light at night or late in the evening.

However, the study noted that LED emissions might be a concern for children and vulnerable people.

According to the study, children have a higher sensitivity to blue light. Exposure to light that is rich blue light could cause discomfort in the elderly.

Previous research has shown that prolonged exposure to bright sunlight may cause eye problems. They identified blue light as the source of the problem.


If you have eyesight concerns due to LED lights, here are some key points:

  • Make sure to pay attention to the wavelength of any LED devices. Limit UV radiation exposure as it can cause eye damage. If you have to use screens, consider using filters.
  • Choose warm white LED or yellow-like lighting that does not strain eyesight.
  • Although LED doesn’t have any harmful effects on our eyesight it can cause some issues if we are exposed to too much.

UV rays have the greatest impact on our eyesight. It is best to avoid these rays.
