Abstract

Purpose: To measure blink rate (BR) and pattern of blink per minute and to compare variations in blink rate and blink pattern of both the genders during different daily living activities.

Methods: The descriptive cross sectional was conducted from November 2019 to May 2020 at The University of Faisalabad and Aspire college, Pakistan. 100 females and 100 males were included age ranging from 18 - 25 years. We measured the blink rate per minute and check the pattern of blink during different tasks i.e. computer use, reading, scotopic condition, gazing, conversation. Blink rate was measured using stopwatch. We engaged the individuals in different tasks using different instruments. Short stories, a healthy conversation, puzzle games, dim light, pencil as a target were used to engage them. The data was analyzed using latest version of SPSS.

Result: By applying Descriptive statistics we measured and compared variations in BR of both the genders. Significant Variations were seen among both the genders during different tasks. Our results showed that BR was excessively reduced from its normal range i.e. (12 - 15 blinks/min) during computer use and while reading and there are more incomplete blinks. BR was also reduced while looking in different gazes and increased while conversation. In scotopic condition, blink rate was reduced.

Conclusion: Study concluded that different daily living activities had an impact on BP and BP and blink rate is significantly reduced in both genders during computer use, while reading and seeing in different gazes due to increased cognitive demand and increased during conversation. Adequate illumination, taking regular breaks during computer use can facilitate in improving blink rate and blink pattern, especially among computer users.
