Blue Light Glasses — Honest Guide
Blue Light Glasses — Honest Guide
Blue light is the high-energy visible light emitted by screens, LED lighting, and the sun. If you spend long hours on a phone, laptop, or tablet, you may have come across blue-light glasses as a way to reduce screen-related eye fatigue.
Here’s an honest look at what blue-light filtering does, what it doesn’t do, and whether it’s right for you.
What blue-light filtering can help with
- Reducing glare from bright screens, particularly in low ambient light
- Easing visual discomfort some users report after long screen sessions
- Reducing perceived brightness of cool-toned LED displays
What the evidence does not currently support
- Blue-light glasses preventing long-term eye damage from screen use
- Blue-light glasses curing or preventing macular degeneration
- Blue-light glasses meaningfully improving sleep without other lifestyle changes
The Advertising Standards Authority (ASA) has ruled against several retailers for unsubstantiated health claims about blue-light glasses. We follow that guidance: blue-light filtering is a comfort upgrade, not a medical product.
How blue-light filtering works
A blue-light filter is a coating or substrate property that reduces the transmission of light in the 400–455 nm wavelength range. Different lens products filter different percentages — anywhere from 10% to 40% of blue light — with the higher filtering levels typically adding a faint yellow tint visible when the lenses are off your face.
Should I get blue-light glasses?
You might benefit if:
- You spend more than 6 hours a day on screens
- You experience eye fatigue, dryness, or headaches by the end of the day
- You game in the evening or work late shifts on bright displays
You probably don’t need them if:
- Your screen time is light and you have no symptoms
- You’re looking for a sleep aid — reducing screen brightness and using night mode is more effective
- You’re looking for medical eye protection — a comprehensive eye exam is the right starting point
How to add blue-light filtering at Ardor
Blue-light filtering can be added at the lens-selection step of checkout when ordering any prescription frame, or as a standalone coating on non-prescription frames. The coating works equally well across all our lens index options (1.50 through 1.74).

Frequently asked questions
Do blue-light glasses really work?
For some users, yes — they can reduce glare and screen-related visual discomfort. Independent research is mixed on whether they reduce eye strain in everyone. They are not a medical product and we don’t market them as one.
Are blue-light glasses safe to wear all day?
Yes. Wearing them all day has no known side effects, though most people only notice the benefit when looking at screens.
Will blue-light glasses help me sleep better?
The relationship between blue light and sleep is complex. Reducing total screen brightness, using your phone’s night mode, and not looking at screens in the hour before bed are all more effective than blue-light glasses alone.
Do blue-light lenses look yellow?
Higher-filtering lenses can have a faint amber tint visible when the lenses are off your face. The tint is usually unnoticeable while you’re wearing them.
Can I get blue-light filtering on prescription lenses?
Yes — it can be added to any prescription lens we make, regardless of index or whether it’s single vision or varifocal.
