Blue Blocker Glasses: What Are They and Who Are They For?
We spend hours in front of screens: smartphones, PCs, tablets, TVs. Blue blocker glasses are designed to protect the eyes from artificial blue light, reduce visual fatigue, and improve sleep quality. In this guide, we discover what they do, who they are for, and which models to choose based on style and daily use.
What are blue blocker lenses?
Blue blocker lenses (or anti blue light) are optical treatments that filter part of the high-energy blue light emitted by digital devices. They do not block all blue light (which is partially useful), but reduce the harmful part responsible for visual fatigue and disruption of the sleep-wake cycle.

Why blue light can be harmful
- Fatigues the eyes: causes burning, dryness, and blurred vision
- Disrupts sleep: reduces melatonin production if used in the evening
- Affects posture: visual fatigue can cause headaches and neck pain
- Chronic overexposure: possible link to long-term retinal damage
Who should use blue blocker glasses?
- Those who work on a PC for more than 4 hours a day
- Students who use devices to study or read
- Those who often watch TV, smartphones, or tablets in the evening
- People prone to dry eyes, headaches, or insomnia
- Those who want visual prevention even without vision defects

Prescription or neutral blue blocker glasses?
✅ With prescription
Perfect for those who need corrective lenses and want complete protection (e.g., presbyopia or myopia).

- Transparent or slightly amber treatment, not blue-tinted or reflective
- Selective light filtering between 380 and 450 nm
- Lens with CE certification and warranty
- Testable with UV blue light (professionals in-store can verify it)
When blue blocker lenses are NOT needed
- If you spend little time in front of screens
- If you already use digital filters on devices (night shift mode)
- If you wear sunglasses with photochromatic lenses (already filtering for UV and intense blue light)
