We will learn about the impact of LED lights on dogs’ eyes in detail. Before we proceed, let us get some crucial information about light and dogs.

Dogs and Light: Do Dogs See the World as Human? 

Many individuals are unaware that dogs do not see the world as humans. While human eyes possess cones in the retina, dogs have Tapetum lucidum cells located behind their retina. 

These cells are reflective layers within the eye, much like a mirror. Therefore, dogs have better night vision compared to us. However, they cannot observe all colors.

Dogs perceive two color variations, which are blue-violet and yellow. Dogs cannot see a difference between green, yellow, and red colors. They rely on the level of brightness to differentiate between different color lights.

When Can LEDs Hurt Dogs’ Eyes?

Both LED lights and LED strip lights are safe for dogs’ eyes. They are designed with keeping all safety points in mind. However, there are some situations when these lights can be problematic for dogs. 

Direct Staring

When you buy products from a reputed LED light manufacturer, it ensures safety. However, make sure your dog does not stare continuously at a bright LED light. 

Automotive headlights and industrial lights emit intense light. It can lead to discomfort and permanent damage to dogs’ eyes. As a result, you need to ensure your dog does not get exposed to such light for an extended period. 

Your pet must have a place to stay safe from direct light exposure. Moreover, the dog’s bed should not be directly beneath a light fixture.     

Flickering Light

Unlike fluorescent bulbs, LED lights do not flicker a lot. But some cheap quality LED lights may have this issue. Rapid and repetitive flashing of light can cause discomfort to the eyes. In rare cases, prolonged exposure can do major harm. 

The flickering light can prompt seizures in dogs with epilepsy. It can cause various other neurological conditions. It happens because the rapid flashing over stimulates the visual cortex of the brain. Flickering of light has neurological effects in humans too.

Improper Use of LED Toys

LED dog toys are getting popular in the market. They are designed to be thrown and caught. Such toys feature blinking lights to attract dogs. Sometimes, such toys can be problematic for the health of dogs. Therefore, when you buy such toys, make sure they are safe.

Blue Light Spectrum

Dogs, like humans, can be harmed by blue light exposure. The eyes can be negatively impacted by exposure to blue light. 

In the visible light spectrum, blue light has a shorter wavelength than other colors. Therefore, it has the potential to penetrate deep into the eyes. As a result, it can affect the health of cells in the retina. The condition is known as blue light toxicity.

Prolonged exposure to blue light can contribute to eye discomfort. In rare cases, it can cause vision problems, redness, and inflammation. The risk of harm depends on the intensity of light and exposure duration.

Dogs have circadian rhythms similar to humans. It informs their bodies when to wake up and sleep. It is regulated by sunlight. Blue light features the same color spectrum as the sun. 

Consequently, if your dog is under blue light, it might feel restless and depressed. In short, blue light can interrupt the nocturnal habit of dogs. 

According to a study, prolonged exposure to blue light can impact a dog’s physical and mental health.

The good news is that LED lights produce negligible blue light. In comparison to traditional lighting, LED light has very low Blue light. 

Still, you should follow a strict bedtime routine for your dog. The lights should not be harsh during bedtime. Also, take your dog for a walk before sleeping. Also, try to eliminate all unnecessary distractions. 

If you use lights for your dog’s shelter, use longer wavelength lights. For example, amber or orange lights have long wavelengths in the visible light spectrum.

UV Light

Some LED lights may produce a negligible amount of UV. The phosphor coating on the LED chip blocks most UV emissions. Still, a small amount of UV can be released by certain blue LED lights. While these lights are safe for your dogs, if you are extra cautious, avoid them.

Pre-existing Eye Conditions

You must be extra careful with your dog’s eyes if it has pre-existing eye diseases, such as corneal ulcers or cataracts. Dogs with such conditions are more susceptible to getting damaged by LED lights.
