“…This is sometimes reported by the patient 6 . In this research there was the possibility of having a group of people with normal ocular exam condition, which naturally shows a palpebral blink frequency and conjugated ocular saccade movement in a lesser degree of consistency 7,8 . However, only a standardized study with healthy volunteers provably evaluated by refraction and complementary psychophysical tests could reveal some evidence of this trend.…”

“…Meibum prevents evaporation of tears. During computer use, blinking reduces and the number of incomplete blinks also increases [46][47][48][49]. Reduced blink rate and incomplete blinks results in uneven distribution and increased evaporation of tears causing dry ocular surfaces.…”

The aim of the study was to determine the prevalence of pterygium among the staff of College of Science, Kwame Nkrumah University of Science and Technology and an association between computer use and pterygium development. A descriptive cross-sectional study in which 150 staff of the College of Science, KNUST, Kumasi, aged 25 to 60 years who volunteered were examined for pterygium. A closeended questionnaire was used to interview the participants. Majority (68.00%) of the participants were males. The ages of the participants ranged from 25 years to 60 years, with a mean age of 38.85 years. Majority (79.33%) of the participants were generally indoor workers while 31(20.67%) were outdoor workers. One hundred and sixteen (77.33%) of the participants were computer users (either at work, home or both) and 34 (22.67%) of the participants were not. The general prevalence of pterygium was 41.33%. The proportion of pterygium was highest among males (43.14%), highest in the age group 41 -50 years (51.22%) and was higher among outdoor workers (51.61%) than indoor workers (40.33%). The proportion of pterygium among computer using participants was 40.52%. A significant association (95 CI, p = 0.02) was observed between the number of hours of computer use per day and pterygium development, with the highest number of cases recorded among those who spent more than 2 hours on the computer daily. Pterygium is more prevalent among outdoor workers than indoor workers. For indoor workers, individuals who spend time on the computer may be predisposed to the development of pterygium, with persons who spend an average of more than two hours per day on the computer both at home and at work , most susceptible.

“…Thus, on the one hand, increasing cognitive demands have been reported to result in a reduction in SBR, both during computer tasks [7][8][9][10][11] and other activities such as reading or watching a video story. 4,5 On the other hand, blinks tend to be associated with large gaze shifts, rather than saccades of smaller amplitude such as those involved in reading, 20,21 partially contributing to sustaining visual stability through momentary suppression of visual input, 16,17 which is particularly relevant for large gaze shifts, were saccadic suppression is less effective.…”

“…4 In addition, a similar reduction in blinking frequency with increasing task complexity has been evidenced in relation to computer use, a field in which spontaneous blinking has been extensively studied in order to understand and alleviate the symptomatology associated with the traditionally known as ''computer vision syndrome''. [7][8][9][10][11] Interestingly, from a different perspective, the increased blink rate observed in studies investigating behavioral indicators of fatigue and drowsiness has been related to a cessation of the attention-driven inhibitor of blinks.…”
