StressFree Anti-blue Light Lenses

StressFree is the innovative lens coating technology from Swisscoat that efficiently reduces the amount of high energy blue light reaching your eyes, cuts glare and increases visual contrast
PLos ONE Scientific Journal in Research Reporting

A clinical research report, “Blue-Light Filtering Spectacle lenses: Optical and Clinical Performances*”, conducted by Hong Kong Polytechnic University was published on January 3, 2017 in the global volume and the most peer-viewed scientific journal, PLos ONE. The clinical performance of some blue lenses in the market was identified through statistical analysis and user experiment. Experiment result is enlightening. The research shows that Swisscoat Blue-Light Filtering Spectacle lenses:

  • can partially filter high-energy short-wavelength light
  • will not hinder our visual functions like color discrimination and contrast sensitivity
  • will not affect our night vision

Clear multifunctional lenses with very low reflection for everyday wear. Increases colour contrast as well as filtering out excess blue.

StressFree Solution

The prolonged exposure to the high-energy visible (HEV) blue-light emitted from digital devices and the sun’s UV rays could cause serious harm to the eyes if left unprotected.

HEV blue-light emitted from these devices penetrates the macular pigment, causing rapid retinal changes that may damage the retina structurally, and also decrease visual acuity. Prolonged UV exposure presents potentially serious eye health issues down the road, elevating the risk of eye diseases such as cataracts and macular degeneration.

StressFree lenses effectively reduce the amount of high-energy blue light and UV rays from reaching your eyes while retaining your visual acuity.

Swisscoat lenses provide unprecedented clarity of vision wherever you look.
