How screens affect your eyes

Blue light from screens is high-energy and demanding on your eyes. Over a long day, it builds into the tired, heavy feeling behind your eyes and contributes to headaches and difficulty focusing. Fovea Blue® Energy lenses block up to 84% of blue light — filtering out the wavelengths most responsible for visual fatigue.

Energy you can feel through the day

Put your glasses on when you start working and keep them on through the day. Energy lenses are designed to be worn indoors and outdoors — comfortable in all settings, with 100% UV protection built in.

Blocks 97% of blue and maintains natural colour perception. Calm lenses block the important blue light range - the exact spectrum that suppresses melatonin production and keeps the brain alert. Because of orange colour and 97% blue light blocking, they maintain natural colour perception.

Supports natural melatonin production. Supports natural melatonin production. By filtering out the blue and green light that suppresses melatonin in the evening, the lenses help remove the light signal that keeps your body alert, allowing natural melatonin production to begin.

You do not have to give up your routine. You can work, scroll, watch TV, or read in the evening without keeping your body in a state of alertness.

Mass-tinted lenses, not coated. Mass tinting is the premium standard most brands skip to cut costs. At Fovea Blue®, the tint is infused throughout the entire lens, rather than applied as a surface coating. This provides real, long-lasting protection, and means your glasses will last for years.

Made for indoor evening use. Not intended for driving.

Every pair of Fovea Blue® lenses comes as standard with:

• Double anti-reflective coating on both sides of the lens
• Anti-static coating (to reduce dust build-up)
• Anti-fog coating
• Hydrophobic coating (to repel water)
• Oleophobic coating (to repel oil and fingerprints)
• 100% UV protection
• Blue anti-reflective coating designed to filter blue light

1. Choose your Energy glasses. Select the pair that suits you best and place your order in just a few minutes.
2. Wear them at the screen. Put them on when you sit down to work or are exposed to harsh artificial light, and keep them on through the day.
3. Feel the relief. Enjoy less eye strain, more focus, and more energy as you power through your day.

Prescription and reading lenses are made to order, with an estimated production time of around 8 weeks. Each lens is tinted individually, so slight differences in lens colour may occur.

If you need correction sooner, the Energy clip-on can be worn over your current glasses and gives you the same blue light filtering without the wait. We keep it in stock in Poland and ship within 1 to 3 business days.
