If you spend a lot of time in front of digital devices, you may have considered purchasing protective glasses to reduce digital eye strain. But which glasses are better: blue light glasses or computer glasses?

We understand the confusion. There is a huge range of protective glasses on the market with terms such as computer glasses, blue light glasses, tinted lenses, anti-reflection, and blue filter. In this article, we answer your most important question: which glasses are better?

Stay tuned until the end, because we'll also share the most important tips for choosing the right glasses!

1. What are computer glasses and are they better than blue light glasses?

To avoid confusion: computer glasses are the same as blue light glasses for daytime use. Both types of glasses filter blue light from screens and reduce strain on the eyes. The difference lies in the wavelengths of blue light that are filtered and the strength of the filter. Later in this article, we explain what level of protection you need.

What are computer glasses?

Computer glasses, also known as screen glasses, is an umbrella term for glasses that protect your eyes from the adverse effects of digital screens. These glasses help reduce digital eye strain, also known as Computer Vision Syndrome (CVS). This is a collection of eye and vision problems caused by prolonged viewing of digital screens.

Because there is no standardization in the industry, any manufacturer can claim to sell "computer glasses" with different filtering and features.

How do computer glasses work?

The main function of computer glasses is to filter blue light. Why? Blue light (380-495nm) carries a lot of energy and is the main culprit behind digital eye strain, dry eyes, headaches, and even retinal damage.

Additional features that computer glasses may have:

Anti-reflective coating: Reduces reflections and improves visibility.
Enlargement: Helps with reading small text and relieves eye strain.
Decentralized pupil distanceEnsures that the lenses are correctly aligned for optimal vision without distortion.

2.What are blue light glasses and are they better than computer glasses?

Blue light glasses is a general term for glasses that filter blue light. There are two types of blue light glasses:

Blue light glasses for daytime use (computer glasses): Protect against blue light from screens and help reduce eye fatigue.
Blue light glasses for evening and nighttime use: Have an orange or red tint and completely block blue light. These glasses help maintain melatonin production and improve sleep quality.

Conclusion: computer glasses or blue light glasses, which is better?

Choose computer glasses/blue light glasses for daytime use if you spend a lot of time in front of a screen and suffer from dry eyes, headaches, or fatigue.
Choose blue light glasses for nighttime use if you use screens after sunset and have trouble falling asleep.

What should you look for when choosing blue light glasses or computer glasses?

Not all blue light glasses are equally effective. Consider the following factors when making your purchase:

Choose the right lens color
- Clear or yellow lenses: Suitable for daytime use, reduces eye fatigue.
- Red or orange lensesSuitable for evening use, completely blocks blue light and promotes sleep.
Request a transmittance spectrum report
- For daytime glasses, at least 50% of blue light (400-500 nm) must be filtered.
- Night glasses must block 100% of blue and green light (400-550 nm).
Protection against the peak wavelength of blue light
- Blue light peaks at 455nm, so make sure your glasses are specifically designed to filter this wavelength.

Because light entering your eyes has a major impact on your health, it is important to choose quality. At Blauwlichtbril, we test all our blue light glasses individually with a spectrophotometer and display the test results in our product descriptions.
