The screen time debate, settled โ plus how to choose the right blue light glasses for your lifestyle.
We spend more time in front of screens than ever before. Laptops, phones, tablets, monitors โ most of us are logging anywhere from 6 to 10 hours of screen time a day, often without thinking twice about what that means for our eyes.
Blue light glasses have become one of the fastest-growing categories in eyewear. But do they actually do anything? Or is it just clever marketing?
Let's break it down.
๐ก What Is Blue Light?
Blue light is a high-energy, short-wavelength light on the visible light spectrum. The sun is its biggest natural source, but digital screens, LED lighting, and fluorescent bulbs all emit it too.
The issue isn't blue light itself โ it's prolonged, close-range exposure. When you're staring at a screen 30โ50cm from your face for hours, your eyes are working harder than they would outdoors, where light sources are further away and your eyes shift focus constantly.

๐๏ธ What Is Digital Eye Strain?
Digital eye strain (also called computer vision syndrome) is a group of symptoms caused by extended screen use. They include:
- Dry or irritated eyes
- Headaches, especially around the eyes and forehead
- Blurred vision after long screen sessions
- Difficulty focusing when you look away from a screen
- Disrupted sleep, particularly when using screens at night
Blue light isn't the only cause. Screen glare, poor posture, and infrequent blinking all contribute. But blue light plays a real role, especially its effect on melatonin production and sleep quality.
๐ The Sleep Foundation has covered how evening blue light exposure can delay your body clock by up to 90 minutes.
โ What Do Blue Light Glasses Actually Do?
Blue light glasses use a specialised lens coating or tinted lens to filter a portion of blue light before it reaches your eyes. At Triskel, our blue light lenses use an anti-blue light acrylic lens with Blue HMC (Hard Multi-Coating), which filters blue light while keeping colour accuracy natural.
The benefits most wearers notice:
1. Reduced Eye Fatigue
Less strain during long work sessions. Your eyes aren't fighting screen glare for hours on end.
2. Fewer Headaches
Many people who work long hours at a desk report fewer tension headaches after switching to blue light glasses.
3. Better Sleep
Wearing blue light glasses in the evening โ especially in the 1 to 2 hours before bed โ can help your body maintain its natural melatonin rhythm and make it easier to fall asleep.
4. More Comfortable Screen Time
Even if you're not noticing specific symptoms, your eyes are working less hard. Over time, that adds up.
โ ๏ธ What Blue Light Glasses Won't Do
It's worth being honest here. Blue light glasses are not a cure-all. They won't:
- Fix existing vision problems
- Replace the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds)
- Eliminate eye strain caused by poor screen ergonomics or dry air
Think of them as one layer of protection, not the whole solution.
๐ถ๏ธ How to Choose the Right Blue Light Glasses
Lens quality matters. Look for lenses with a dedicated blue light filter coating. Triskel's blue light range uses anti-blue light acrylic lenses with Blue HMC coating for reliable, consistent filtering.
Consider your frame. You'll be wearing these for hours, so fit and comfort are just as important as the lens. Spring hinges, lightweight frames, and the right fit profile make a real difference across a long workday.
Match it to your use case. If you need sun protection too, the Florida Clip-On gives you blue light lenses with a TAC clip-on for outdoors. If it's purely desk work, the Montreal, Lyon, or Quebec are purpose-built for screen time in a range of styles and fits.
โจ Final Thoughts
The research on blue light glasses is still evolving, but what's clear is this: if you spend most of your day in front of a screen and regularly experience tired eyes, headaches, or trouble sleeping, blue light glasses are a low-cost, low-effort thing to try.
At Triskel, our blue light glasses start at $29.90 and are built with the same attention to fit and quality as the rest of the range. No compromise on style, no compromise on function.
