Christopher Cloos Blue Light

While the brand primarily sells non-prescription eyewear designed to filter out high-energy blue light from digital screens, many of their frames can be fitted with custom prescription lenses. You can usually take them to an optometrist or use an online prescription service with the frame measurements.

Christopher Cloos is known for crafting their premium frames using high-quality Italian bio-acetate, which is a more sustainable alternative to traditional plastics. The glasses feature durable hinges and a lightweight construction to ensure comfort during extended wear.

These specific lenses are engineered with a clear spectral filter to reduce indoor blue light exposure from computers and smartphones to improve sleep quality. Unless you purchase a specifically tinted sunglasses variant, they do not offer UV protection for outdoor sun exposure.

You should clean the lenses using a microfiber cloth and a small amount of lens cleaner to prevent scratching the blue light coating. It is recommended to avoid using harsh household chemicals or wiping the lenses with your shirt, as this can degrade the protective spectral filter over time.
