Evaluation of a Night Spectacle Correction Concerning an Improvement of Mesopic Vision Quality

University of Applied Sciences Jena·interventional·Posted Nov 16, 2016·Updated Feb 28, 2019

In Brief

A clinical study evaluating Spectacle/Glasses for Myopia-Night Blindness. Completed, enrolled 100 participants across 3 sites.

Detailed Summary

Reduced quality of vision and glare in twilight or night are frequently mentioned complaints within the optometric examination. A reason for these problems could be a myopic refractive shift in dark light conditions, commonly known as night myopia or twilight myopia. The aim of this study was to investigate whether quality of vision in twilight or night could be improved by a spectacle correction optimized for mesopic light conditions. Moreover, objective refraction in large pupils measured by aberrometry was compared to subjective mesopic refraction.
