What Are Blue Light Blocking Glasses?

With technology becoming an essential part of everyday life, blue light exposure has quickly emerged as a major health concern. As we spend more hours on digital screens, people are experiencing more eye fatigue, sleep disruption, and digital eye strain than ever before. This has created a growing demand for blue light blocking glasses, which are designed to filter certain wavelengths of high-energy light.

This article explains what blue light is, how blue light glasses work, whether they’re effective, and where you can buy high-quality options such as those offered by EFE Glasses.

What Is Blue Light?

Blue light refers to a band of high-energy visible (HEV) light, with wavelengths between 380 nm and 500 nm. It naturally exists in sunlight and plays a vital role in maintaining a healthy circadian rhythm, boosting alertness, and improving mood during daytime hours.

However, blue light also comes from artificial sources such as:

• Smartphone screens

• Tablets and laptops

• LED and fluorescent lighting

• Televisions

• Energy-saving bulbs

While natural blue light during the day can enhance focus, excessive exposure to artificial blue light—especially at night—can cause digital eye strain, headaches, and sleep disturbances. Because of these issues, there is a rising interest in eyewear designed to filter blue light and minimize the strain caused by prolonged screen use.

What Are Blue Light Blocking Glasses?

Blue light blocking glasses are designed with special lenses or coatings that absorb or filter the high-energy blue wavelengths emitted from digital devices. These glasses help reduce glare, limit overexposure, and create a more comfortable visual experience.

There are two main types of blue light filter glasses:

1. Coated Blue Light Glasses

These lenses use a clear or nearly clear coating that reflects part of the blue light spectrum. Some users may notice a slight blue or yellow reflection, but the lenses typically look natural and stylish.

This type is popular among people who prefer minimal tint, want everyday wearable glasses, and need light blue light protection for office or mobile use. Brands like EFE Glasses offer coated blue light lenses that maintain natural color perception while reducing digital strain.

2. Amber-Tinted Blue Light Glasses

Amber-tinted or yellow-tinted lenses block a higher percentage of blue and violet light. These are recommended for:

• Long computer work sessions

• Gaming

• Evening screen use

• Individuals sensitive to bright screens

The tint helps improve contrast, reduce glare, and create a calming visual effect. Although the color shift is more noticeable, many users prefer maximum blue light filtering, especially if they struggle with nighttime screen exposure.

Are Blue Light Blocking Glasses Effective?

The popularity of blue light glasses continues to rise, especially among people who spend extended hours on screens. While experts debate the extent of their effectiveness, several studies and user reports highlight meaningful benefits.

Potential Benefits of Blue Light Glasses:

• Reduced Digital Eye Strain (DES):
  People who work on screens for long hours often report less fatigue and discomfort when using blue light filter glasses.

• Improved Sleep Quality:
  Over 90% of surveyed users say blue light glasses help them fall asleep more easily by limiting stimulating blue wavelengths before bedtime.

• Reduced Glare:
  The primary purpose behind developing blue light lenses was to reduce harsh screen glare. Many review studies confirm that these glasses help improve comfort during prolonged screen use.

• Better Visual Comfort & Focus:
  Users often experience improved concentration during long work or study sessions.

While blue light glasses are not a cure-all, they can offer meaningful relief for people struggling with digital eye strain, excessive screen brightness, or sleep disruption.

How Can I Tell If My Glasses Filter Blue Light?

It’s easy to identify whether a pair of glasses includes blue light blocking features. Here are a few clues:

Lens Color

• Yellow, amber, or orange lenses almost always indicate stronger blue light filtering.

• Clear lenses may still filter blue light and often show a faint blue or yellow reflection under certain lighting.

Coating Reflection

Blue light blocking coatings often reflect a subtle blue/purple sheen. This indicates that a portion of the blue wavelengths is being deflected.

Screen Glare Test

If your glasses noticeably reduce glare and improve comfort when looking at screens, they likely contain a blue light filter.
