Investigating the effects of simulated high altitude on colour discrimination.

ABSTRACT:

Purpose

To quantify changes in colour vision immediately after exposure to different altitudes of low-pressure hypoxia.

Methods

The study involved 35 healthy participants (ages 20-26). Colour vision was assessed using the Farnsworth-Munsell 100-Hue test at eight different altitudes (condition 1: ground, condition 2: 3500 m, condition 3: 3500 m after 40 min, condition 4: 4000 m, condition 5: 4000 m after 40 min, condition 6: 4500 m, condition 7: 4500 m after 40 min, condition 8: back to the ground). Data were analysed using Analysis of Variance (ANOVA), paired t-test, and χ² test .

Results

Total Error Score (TES) increased with altitude and hypoxia duration, with higher TES in condition 8 than in condition 1. There were significant TES differences between co
