Background:

Among all types of vision impairment, refractive errors remain a common issue around the world. Inappropriately, if an individual continues using laptop for about 7-8 hours daily, this put pressure on the eyes causing refractive errors that include myopia, hyperopia and astigmatism but since it occurs gradually, people seldom know they are suffering from them.

Purpose of the study:

Specifically, this research will seek to establish the frequency and incidence of refractive errors; myopia, hyperopia and astigmatism among the lad emmetropic employees engaged in the abundant screen time.

Materials and methods:

The sample comprised 185 participants aged 18-35 years: 102 of them male (55.1 percent) and 83 females (44.9 percent). The following equipment was used for the assessment of refractive errors among the students: Auto refractometer, retinoscopy, and a distance Log Mar chart, and trial box and pen torch.

Results:

Among the participants, 39.5 percent were myopic, 11.4 percent were emmetropic. More than half of the students had normal vision; 8 percent of the students were hypermetropic, while 38.4 percent had astigmatism.

Conclusion:

Presenting a work-related prevalence rate of 39.5 percent for myopia and 38.4 percent for astigmatism, the study was also able to establish that participants underwent more than 7 hours of cross. Emmetropia and hyperopia were less frequent in the whole sample, 11.4 percent and 10.8 percent, respectively. The only recorded difference was a slightly higher proportion of males in the study, where they considered 55.1 percent. Overall, these findings point to the high prevalence of myopia and astigmatism and stress the importance of prevention strategies and more research regarding screen related visual related damage.
