What Is Blue Light & Why Filter It?

Blue light is the high-energy visible light (HEV) in the 400–500 nm wavelength range. It is emitted naturally by the sun and artificially by computer screens, smartphones, tablets, LED lighting, and TVs. While some blue light exposure is normal and even beneficial during the day, extended exposure — especially from close-range screens — can cause problems.

The Effects of Too Much Blue Light

  • Digital eye strain — tired, dry, and irritated eyes after hours of screen time
  • Headaches — tension that builds behind the eyes through the day
  • Disrupted sleep — blue light suppresses melatonin production, making it harder to fall asleep and stay asleep if you use screens in the evening
  • Potential long-term concerns — ongoing research is studying the cumulative effect of blue light on retinal health over decades

Blue light lenses filter the most problematic wavelengths (415–455 nm) while letting beneficial light through. They can be added to any lens type — single vision, bifocal, progressive, or computer lenses — or worn without a prescription.

Who Benefits from Blue Light Lenses?

Blue light filtering is valuable for anyone who spends significant time in front of screens:

  • Office workers — 8+ hours of computer use per day
  • Students — online classes, research, and study on laptops and tablets
  • Gamers — long sessions on monitors and TVs
  • Children and teenagers — increasing screen time for school and entertainment. In Alberta, kids under 19 get a free annual eye test — ask about blue light protection at their appointment.
  • Evening screen users — anyone who uses phones, tablets, or laptops within 2 hours of bedtime benefits the most from blue light filtering's sleep improvements
  • People who already have eye fatigue — if you experience headaches, dry eyes, or tired eyes by the end of the day, blue light lenses can make a noticeable difference

Blue light protection does not require a prescription — we carry plano (non-prescription) blue light glasses for people with perfect vision who just want screen protection.

Blue Light Lenses vs Computer Lenses

They solve different problems — and work best together

Blue Light Lenses

A coating or filter that blocks harmful blue wavelengths from reaching your eyes. It addresses the light spectrum problem.

  • Can be added to any lens type
  • Reduces eye fatigue and improves sleep
  • Available with or without prescription
  • Does not change the lens design or viewing zones

Computer Lenses

A prescription lens design optimized for screen distance with a wider intermediate zone. It addresses the ergonomic problem.

  • Requires a prescription (typically for over-40 progressive wearers)
  • Eliminates head tilting and neck strain
  • Wider intermediate zone than standard progressives
  • Not for driving or distance use

Best combo: Computer lenses with blue light coating — fixes both the ergonomic and the light problems. Add it to your 3-for-1 deal.

Tips for Reducing Digital Eye Strain

Blue light lenses are part of the solution — combine them with these habits for best results

  • The 20-20-20 rule — every 20 minutes, look at something 20 feet away for 20 seconds. This relaxes your focusing muscles and reduces strain.
  • Blink consciously — screen use reduces your blink rate by up to 60%, leading to dry eyes. Make a habit of blinking regularly.
  • Position your screen correctly — your monitor should be at arm's length, with the top of the screen at or slightly below eye level.
  • Reduce screen brightness in the evening — combine with blue light lenses for maximum melatonin protection before bed.
  • Use proper lighting — avoid working in a dark room with a bright screen. Match ambient lighting to screen brightness to reduce contrast strain.
  • Consider computer lenses — if you are over 40 and wear progressives, dedicated computer lenses with blue light coating are the best solution for screen comfort.

Frequently Asked Questions About Blue Light Lenses

What are blue light lenses?

Blue light lenses have a special coating or embedded filter that blocks a portion of the high-energy blue light (415–455 nm) emitted by screens, LED lighting, and electronic devices. They reduce eye fatigue, may improve sleep quality, and can be added to any prescription type or worn without a prescription.

Do blue light glasses actually work?

Many people report reduced eye fatigue, fewer headaches, and improved sleep quality with blue light lenses. The strongest evidence supports their role in reducing melatonin suppression — filtering blue light in the evening helps your body maintain its natural sleep-wake cycle. For daytime relief, they work best combined with proper screen ergonomics and the 20-20-20 rule.

Can I get blue light lenses without a prescription?

Yes. Blue light lenses are available as plano (non-prescription) glasses for people with perfect vision who want screen protection. They are also available with single vision, bifocal, progressive, and computer lens prescriptions.

Do blue light lenses have a yellow tint?

Some blue light lenses have a slight yellow or amber tint, while modern coatings like Premium Blue AR are virtually clear. The tint depends on the filtration level — higher filtration means more noticeable colour. Our opticians can show you samples so you choose the level that works best for you.

Should kids wear blue light lenses?

Children spend increasing time on screens for school and play, so blue light lenses can help reduce screen fatigue. In Alberta, children under 19 qualify for a free annual eye test — a great time to discuss screen habits and blue light protection.

What is the difference between blue light lenses and computer lenses?

Blue light lenses are a coating that blocks blue wavelengths — they can be added to any lens. Computer lenses are a prescription design optimized for screen distance with a wider intermediate zone. They solve different problems and work best together: computer lenses for the ergonomic issue, blue light for the light spectrum.

Are blue light lenses included in your 3-for-1 deal?

Blue light filtering is available as an add-on to any pair in our 3-for-1 deal. Three pairs of glasses start at $199 — add blue light protection to one, two, or all three. A free eye test with the Essilor R800 is included.
