UNBOXING
Protect your eyes from harmful blue light
Blue light is coming from screens of laptops, smartphones, tvs and even LED lights. It damages our sight and causes discomfort. The optic nerves are constantly contracting and relaxing to focus the image properly. This leads to their overexertion. No wonder that many people complain about fatigue, blurred vision, headeaches and insomnia after prolonged work at the computer.
We cannot eliminate blue light from our lives, all we can do is to limit its harmful effects.
Undoubtedly, NoBlue glasses can help here. They will protect your eyes and improve your well-being
In this graph, we can see the full spectrum of light that reaches our eyes.
Here, the light is filtered through our glasses. Harmful UV light and about 40% of blue light have been removed. The glasses have a balanced filter that blocks only unwanted light (380-500nm).
