Summary

This study investigates the effects of blue light-blocking glasses compared to standard lenses on contrast sensitivity and visual fatigue in myopic and non-myopic adults. With the growing use of digital screens, blue light exposure has raised concerns due to potential eye strain, sleep disruption, and visual fatigue.

Conditions

  • Myopia

Interventions

COMBINATION_PRODUCT

Blue Light-Blocking Glasses (Intervention Group)

Participants in this arm wore blue light-blocking glasses designed to filter out a portion of short-wavelength blue light. These lenses were intended to reduce eye strain and protect against blue light exposure, especially during prolonged screen time. Participants used blue light-blocking glasses consistently throughout the study period to assess their effect on contrast sensitivity and visual fatigue.

DIAGNOSTIC_TEST

Standard Lenses (Control Group)

Participants in this arm wore standard lenses without any blue light-blocking properties. These lenses allow the full spectrum of visible light to pass through and serve as a baseline control to measure against the blue light-blocking glasses. Participants used these lenses under the same conditions to assess contrast sensitivity and visual fatigue without blue light filtration.
