Eye (London, England)·2017

Animal studies show ultraviolet (UV) and visible light cause ocular damage relevant to humans. This evidence supports the need for eye protection against UV and blue light, particularly in sunglasses.

Area of Science:

  • Ophthalmology
  • Photobiology
  • Toxicology

Background:

  • The human and animal eye possesses inherent photochemical sensitivity due to naturally occurring chromophores.
  • Lifelong exposure to light, especially at shorter wavelengths, increases the potential for ocular damage.
  • Divergent interpretations exist regarding the relevance of animal studies for human ocular pathology and the necessity of eye protection.

Purpose of the Study:

  • To review the relevance of animal observations on UV and visible light-induced ocular changes for human pathology.
  • To discuss challenges in epidemiological surveys and animal studies concerning light-induced eye damage.
  • To outline natural and artificial eye protection strategies against light radiation.

Main Methods:

  • Review of epidemiological surveys and human clinical observations.

  • Analysis of laboratory-based animal studies on radiation damage.
  • Discussion of theoretical calculations and model studies.
  • Outline of natural and artificial eye protection mechanisms.

    • Main Results:

    • Laboratory studies provide significant evidence that UV and short-wavelength visible light induce acute and chronic ocular changes.
    • These light-induced changes can lead to irreversible damage to ocular structures.
    • There is a growing consensus, supported by major US visual health organizations, for incorporating UV and blue light protection into eyewear.

    Conclusions:

    • Evidence from multiple fields, including laboratory studies, supports the detrimental effects of UV and blue light on ocular health.
    • Animal observations are relevant for understanding human pathology related to light-induced eye damage.
    • Enhanced eye protection, specifically against UV and blue light in sunglasses, is recommended for public health.
