In today’s digital world, screen time is unavoidable — from smartphones and tablets to laptops and televisions. While these devices are a core part of modern life, extended exposure to them has led to an increase in digital eye strain and related issues like headaches.
One effective solution many people turn to is blue light glasses. But do they actually help with headaches? And if so, how?
In this guide, we’ll break down the science behind blue light, how it affects the body, and how blue light filtering lenses can help reduce discomfort.
What Is Blue Light and Why Does It Matter?
Blue light is part of the visible light spectrum. It has a short wavelength and high energy, and is emitted naturally by the sun as well as artificially by digital screens and LED lighting.
While blue light in small doses isn’t harmful — and is even beneficial for regulating our sleep-wake cycle — excessive exposure, especially during the evening, has been linked to:
- Eye strain
- Dry or irritated eyes
- Fatigue
- Headaches
- Disrupted sleep
Because our eyes aren’t very effective at filtering out blue light, prolonged exposure from screens can lead to symptoms collectively known as digital eye strain.
How Blue Light Glasses Help Relieve Headaches
Blue light glasses feature a special coating that filters out a portion of high-energy blue light emitted by digital screens. By reducing the amount of blue light entering the eye, these glasses help minimise visual stress, especially during prolonged screen use.
For people who experience headaches after long computer sessions, this filtering effect can:
- Ease tension in the eye muscles
- Improve contrast on the screen
- Reduce glare and reflections
- Promote a more relaxed viewing experience
These changes may significantly reduce the likelihood of headaches, particularly those caused by tension or visual fatigue.
Can I Use Prescription Lenses with Blue Light Protection?
Absolutely. If you already wear prescription glasses, you don’t need a second pair. Most optical retailers now offer blue light filter coatings as an optional upgrade on prescription lenses.
This means you can benefit from both clear, corrected vision and blue light protection in a single pair of glasses. At Glasses Store, we allow you to customise your lenses with options such as blue light filters, anti-reflective coatings, and even tints — so you get the protection and clarity you need.
Other Benefits of Blue Light Glasses
While headache relief is a top reason people try blue light glasses, there are other noteworthy benefits:
- Reduced Eye Strain: By softening the impact of screen glare, these glasses help reduce symptoms of digital eye strain such as tired eyes and blurred vision.
- Improved Focus: When your eyes are less fatigued, it’s easier to concentrate, especially on detail-heavy tasks.
- Better Sleep: Blue light exposure at night can suppress melatonin, the hormone that helps regulate sleep. Wearing blue light glasses in the evening may support better sleep quality.
Are Blue Light Glasses Right for You?
If you spend multiple hours a day using digital devices — for work, study, or entertainment — and experience headaches or eye discomfort, blue light glasses are worth considering.
They are especially helpful if:
- You work in front of a computer all day
- You experience screen-related headaches or migraines
- You struggle with sleep after late-night screen use
- You already wear prescription glasses and want added protection
Final Thoughts
Blue light glasses aren’t a cure-all, but they can be a practical and non-invasive way to reduce the visual strain and headaches associated with digital device use. By filtering out a portion of harmful light, they offer relief to the eyes and support better wellbeing overall.
