Blue light filter glasses are specially designed to block or filter much of the blue light that digital screens emit. This is in contrast to normal glasses, which are primarily intended to correct visual impairments and do not specifically filter blue light. Our Zayna blue light filter glasses reduce eye strain, improve your sleep quality and protect your eyes from potentially harmful light.

Scientific research shows that blue light glasses are effective in reducing blue light exposure, which can lead to better sleep patterns and reduced eye strain. Customers who use our Zayna glasses report a noticeable decrease in eye strain, especially after prolonged use of digital devices.
