%X PURPOSE: Assess the changes in the visual capabilities related to protector masks that are mandatory in emergency situations. The study was carried out in mesopic conditions.METHODS: 36 adults were assessed. Everyone was from both genders, ranging 18 to 49 years old, with an average of 30 +- 8 years old. Face protectors screens have been utilized on Individual Protection Kits for emergency situations. Every measure was conducted by the same examiner and into the same laboratory in mesopic conditions. Visual cuity was evaluated by means of the Sloan´s test at 100% and 5% of contrast in logarithmic units. The contrast Sensitivity with the CVS1000 test and the colour perception with Ishihara´s test (each test was accomplished by the manufacturer´s recommendations).RESULTS: The capacity for distinguishing details in the assessment carried out without a protector screen was of -0.05 +- 0.05 logMAR, and with a protector screen was of 0.00+-0.11 logMAR being the difference statistically significant. Contrast Sensitivty values are lower when a protector filter is interjected, with p-valor 0.0013. Regarding coloru perception significative differences were detected after protector screen application and withdrawal.CONCLUSION: In mesopic ocnditions, spatial resolution, contrast sensitivity and colour perception are signifcantly more decreased due to face protector needed for emergency situations.
