Essilor Smart Blue Filter

The Essilor Smart Blue Filter works by altering the spectral transmission of the lens to specifically scatter and filter out short-wavelength blue light. This light, which ranges from 415 to 455 nanometers, is considered the most harmful to the retina. The technology blocks a significant portion of this light without distorting your overall color perception.

Unlike older blue light filtering technologies, the Essilor Smart Blue Filter is designed to be virtually clear without an obvious yellow tint. Essilor uses a light-reabsorbing technology within the lens material itself. This allows for optimal transparency and cosmetic appeal while still protecting your eyes.

Yes, the Smart Blue Filter is an integrated technology that can be baked directly into Essilor's popular Crizal anti-reflective coatings. This combination ensures you get smudge resistance, UV protection, and blue light filtering in one lens. It is highly recommended for patients who spend hours staring at digital screens.

Anyone who works in an office or spends multiple hours a day looking at LED screens will benefit from these lenses. By reducing short-wavelength blue light exposure, the lenses help mitigate digital eye strain, dry eyes, and blurred vision. They are also popular for evening computer use to prevent blue light from disrupting sleep patterns.
