When To Wear Blue Light Blocking Lenses

Blue light is all around us. It can be found in natural sunlight. It can also be found in LED light bulbs, television screens, smartphone displays, and computer monitors. 

You have heard that blue light can be great. You’ve also heard that it can be potentially damaging. 

So when is the right time to wear blue light blocking lenses?

Computer Use

Anytime that you are using a desktop monitor or laptop computer you should be wearing your blue light blocking lenses. 

Many employees spend at least eight hours a day looking at a computer screen. That is a lot of time to be exposed to the blue light that is emitted from the screens. Overexposure can lead to some potentially uncomfortable side effects, including dry eyes and headaches. 

While on the computer, be sure to also blink frequently, have good sitting posture and set up your workspace to reduce digital eye strain. 

Smartphones and Tablets

After spending those eight hours working on screens, people often follow it up with several hours using electronic, handheld devices. The screens on smartphones, tablets, and e-readers also emit blue light. To reduce the potentially harmful effects of the blue light, use your lenses each time you reach for your device. 

It has been shown that people reach for their phones more than 120 times each day. It can be helpful to leave your blue light blocking lenses on during the periods of time that you often use your phone. 


Blue light is found naturally in sunlight. Exposure to the sun can provide necessary Vitamin D. While being aware of the impacts of the sun on your skin, be sure to consider the impact on your eyes as well. 

Blue light blocking lenses should specifically allow the healthy amount of blue light into your body while also blocking out the potentially harmful amounts. Not all blue light lenses are created equal. Be sure to learn at what wavelength blue light is reduced. 

Around the Home

Keep in mind that LED lightbulbs and televisions both emit blue light. If you spend time watching television, be sure to slide your lenses on. If you are unable to change the lightbulbs in your residence, consider adding additional light sources that do not use LED bulbs. Minimizing your exposure to blue light from this source can be a great step towards prevention.

Blue light blocking lenses should be worn anytime you are using a screen or device that emits blue light. Keep your eyes healthy and reduce digital eye strain with a great pair of blue light blocking lenses.
