How Will Focus (Previously Day) Swannies Blue Light Blocking Glasses Help Me Optimize My Work?

Blue light in the shorter wavelength range carries more energy and can scatter more easily than longer wavelengths. When using digital devices for extended periods, this may contribute to visual discomfort for some people.

Extended screen use is commonly associated with digital eye strain, which can include symptoms such as dry or tired eyes, discomfort, and headaches.

Focus (Previously Day) Swannies are designed to reduce a portion of higher energy blue light below 450nm while maintaining clear, natural vision. By moderating this part of the spectrum, the lenses aim to support visual comfort during prolonged screen sessions.

Importantly, Focus (Previously Day) lenses are calibrated to still allow some blue light to pass through. Blue light exposure during daytime hours plays a role in supporting alertness and maintaining a normal sleep wake rhythm. Maintaining this balance helps ensure the lenses do not overly darken vision or interfere with normal daytime light cues.

By supporting visual comfort while preserving natural light balance, Focus (Previously Day) Swannies are designed to help you stay comfortable and focused throughout the workday.
