4 Situations That Call For Blue Light Lenses

Blue light is all around us and can be found in natural sunlight and also in digital devices, such as TVs, smartphone displays, and computer monitors. While it can be good for your eyes, too much exposure can also be potentially damaging. Here are some of the right times to wear blue light blocking lenses.

Blue light glasses feature tinted lenses with anti-glare protection. These lenses will limit your exposure to blue light, which can be found in your cell phone, computer monitor, certain light bulbs, and even sunshine. 

While some exposure to blue light can be good for your eyes, too much exposure can negatively impact your eye health. Your Calgary eye doctor may suggest blue light lenses because they offer many benefits, including: 

  • Reduced eye strain
  • Improved sleep habits
  • Lower risk of developing age-related macular degeneration (AMD)
  • Alleviation of any eye discomfort

If you spend a lot of time on digital devices, it can be helpful to talk to your Calgary optometrist about using blue light lenses with your eyeglasses.

When to Wear Blue Light Blocking Lenses 

Blue light can be found all around you. It can be found in natural sunlight, LED light bulbs, and digital devices, such as television, smartphone displays, and computer monitors. While a certain amount of blue light can be good for you, overexposure can be potentially damaging to your vision. 


Here are some of the right times to wear blue light blocking lenses: 

  1. When Using the Computer 

Anytime you are using your laptop or desktop monitor, you should wear your blue light blocking lenses. This is especially true if you spend the majority of your day working with such devices. The overexposure to blue light can lead to uncomfortable side effects, such as: 

  • Eye strain and fatigue 
  • Dry eyes
  • Headaches 

In addition to wearing your blue light lenses when on digital devices, make sure to blink frequently, have a good sitting posture, and set up your workspace to reduce digital eye strain. 


  1. When You Are On Your Smartphone or Tablet 

After working all day on your computer, you may follow it up with several hours on electronic, handheld devices, such as your smartphone or tablet. These devices also emit blue light, so to reduce the harmful effects, make sure you use your blue light lenses every time you reach for these devices. 

Blue Light Lenses Can Improve Your Quality of Sleep 

In general, you should avoid using blue light devices before bedtime, as the high energy frequency can keep you up at night. However, blue light lenses can reduce your exposure to such high energy, allowing you to use such devices and still enjoy a restful night’s sleep.

  1. When You Are Outside 

Blue light is naturally found in sunlight and while exposure to the sun can provide necessary Vitamin D, too much exposure can have a negative impact on your eyes. Blue light lenses allow a healthy amount of blue light into your body, while blocking out the potentially harmful amounts. 

Talk To Your Calgary Optometrist About Which Blue Light Lenses Are Right For You 

Remember that not all blue light lenses are created equal. Before you make a purchase, make sure to ask your optometrist at what wavelength blue light is reduced. 

  1. When You Are At Home 

It’s important to remember that both LED light bulbs and televisions emit blue light. If you spend a lot of time watching television, make sure to wear your blue light lenses. If you have LED light bulbs at home and cannot change them, consider adding additional light sources that don’t use LED bulbs. 

Making Certain Changes Can Go A Long Way in Protecting Your Eye Health

Minimizing your exposure to blue light from such sources can be a great step towards preventing dry eyes, digital eye strain, and it may even lower your risk of developing serious eye conditions, such as AMD.
