What is blue light?

In our screen-dominated world, your eyes are under constant demand. Protecting them from the effects of blue light has never been more important.

Blue light sits within the visible light spectrum, with wavelengths between 400nm and 500nm. It is the highest-energy visible light and plays a beneficial role in nature — boosting alertness, improving mood, enhancing reaction times, and helping regulate our circadian rhythm during daylight hours.

However, in today’s environment we face increasing exposure to artificial blue light from digital screens (computers, smartphones, tablets), LED lighting, and energy-efficient bulbs. Prolonged exposure to this high-energy light — particularly the more intense peaks around 455nm — can penetrate deeper into the eye, contributing to retinal stress, digital eye strain, tired and irritated eyes, headaches, and disrupted sleep by suppressing natural melatonin production.

Our UV400 blue light filtering lenses are specially designed to reduce these harmful effects, helping protect your eyes and support healthier daily screen use, better sleep, and overall wellbeing.

How Blue Light Filtering Glasses Help

Wearing quality blue light glasses provides practical protection with noticeable benefits:

  • Long-term eye protection — Helps shield the eyes from cumulative exposure that may affect retinal health over time.
  • Reduced digital eye strain — Eases tired, heavy eyes after extended screen sessions.
  • Better sleep support — Minimises melatonin suppression, especially from evening screen use, making it easier to wind down.
  • Fewer headaches — Many users experience relief from screen-related headaches.
  • Less dry eye discomfort — Reduces irritation and dryness often triggered by prolonged digital device use.
  • All-day versatility — Suitable for work, study, driving, and leisure.

Who Can Benefit?

Blue light filtering lenses are ideal for office workers, students, gamers, remote professionals, and anyone spending significant time in front of screens. They can even enhance sunglasses for outdoor use, providing protection from both natural and artificial blue light.

Taking Control of Screen Exposure

Modern life makes limiting screen time challenging. Adults often spend over six hours per day on digital devices, well beyond comfortable levels. While reducing exposure remains ideal, blue light filtering lenses offer a smart, effective layer of defence for real-world use.

Give your eyes the protection they deserve in today’s digital world.

Are screens really that bad?

Our eyes were never designed for hours of continuous close-up focus on digital screens. In nature, they rest and relax when viewing distant objects, typically 20 feet or more away. Yet in today’s world, we spend long periods staring at laptops, monitors, phones, and tablets from just 18–24 inches away.

This prolonged near-focus forces the ciliary muscle inside the eye to work overtime, constantly adjusting and straining. Over time, this can lead to Digital Eye Strain — also known as Computer Vision Syndrome — with common symptoms including dry eyes, headaches, blurred vision, tired eyes, and even neck and shoulder discomfort.

Our blue light filtering lenses are specially engineered to combat these effects, this helps reduce eye strain, fatigue, and discomfort, allowing you to work and browse more comfortably for longer.

Why are most of your glasses lenses clear?

Our clear blue light blocking lenses are discreet and virtually invisible, preserving natural colour vision with no yellow tint. This makes them ideal for all-day wear, whether you're working, studying, or relaxing. Not everyone feels comfortable wearing glasses with tints.

While we also offer tinted options, our clear lenses are specifically designed for those who prioritise accurate colour rendering and everyday comfort. They provide a 20% block of blue light at 450nm, delivering subtle yet effective protection exactly where it matters most.

Everyday Uses for Clear Blue Light Blocking Glasses

  • Extended screen work — Perfect for long hours in front of computers, laptops, or multiple monitors, helping to reduce digital eye strain and fatigue.
  • Daily device use — Excellent for smartphones, tablets, and TV viewing, especially in the evenings when blue light can affect sleep quality.
  • Office & indoor environments — Helps minimise eye discomfort and headaches caused by bright LED and fluorescent lighting.
  • Gaming sessions — Keeps your eyes comfortable during extended play, reducing strain and blurred vision.
  • Remote work & video calls — Provides greater comfort and clearer vision during long hours of online meetings and calls.
  • Evening wind-down — Supports better sleep by reducing blue light exposure before bed while using tablets or other devices.
  • Students & online learning — Ideal for heavy screen use during schoolwork, lectures, and digital study sessions.
