Assessing Human Eye Exposure to UV Light: A Narrative Review

Area of Science:

• Ophthalmology
• Photobiology
• Environmental Health

Background:

• Ultraviolet (UV) light exposure is linked to various ocular pathologies, necessitating accurate exposure assessment for medical and prevention strategies.
• Current methods for estimating UV exposure, such as ambient irradiance measurements, are insufficient for the ocular region, and dermal exposure tools have limitations.
• Accurate quantification of ocular UV exposure is vital for understanding its contribution to eye diseases and developing effective protective measures.

Approach:

• A comprehensive literature review was conducted to analyze existing research on ocular UV exposure.
• Three novel methods for assessing ocular UV exposure were investigated: anthropomorphic manikins, wearable sensors, and numerical simulations.
• The study critically evaluates the specific objectives, inherent limitations, and obtained results for each of these three distinct methodologies.

Key Points:

• Ambient irradiance is not a reliable proxy for effective ocular UV exposure.
• Existing tools designed for dermal UV exposure assessment are inadequate for the ocular region.
• Anthropomorphic manikins, wearable sensors, and numerical simulations offer promising alternatives for quantifying ocular UV exposure.

Conclusions:

• Developing accurate methods to measure ocular UV exposure is essential for understanding and mitigating associated eye pathologies.
• The reviewed methods (manikins, sensors, simulations) provide a foundation for more precise ocular UV exposure assessment.
• Further research and validation of these advanced techniques are needed to improve eye protection strategies against UV radiation.
