Which lens feature helps reduce eye strain during prolonged use?

Blue light blocking lenses are designed to filter out a significant portion of blue light emitted from screens and artificial lighting. Prolonged exposure to blue light can contribute to digital eye strain, leading to symptoms such as discomfort, fatigue, and blurred vision. By incorporating a blue light filtering feature, these lenses help to minimize these adverse effects, allowing for more comfortable extended use of digital devices.

This feature has become increasingly important in our digital age, where many individuals spend hours in front of computers, tablets, and smartphones. Wearing blue light blocking lenses can help reduce glare and improve contrast, resulting in less strain on the eyes while reading or working on screens.

Other lens features, while beneficial in their own right, do not specifically address eye strain related to prolonged screen use. For instance, gradient tints provide varying levels of sun protection but do not target digital eye strain. Anti-fog coatings are useful for clarity in varying temperatures, and scratch resistance contributes to the durability of the lenses but does not enhance eye comfort during extended viewing.
