“…One report studied the relationship between kinetic visual acuity and dynamic stereoacuity and the effects of anisometropia on kinetic visual acuity and dynamic stereoacuity assessment. [ 20 ] Kinetic visual acuity was significantly higher for men than for women. Dynamic stereoacuity attributable to kinetic visual acuity; kinetic visual acuity; and dynamic stereoacuity attributable to anisometropia did not significantly differ between sexes and were not strongly correlated.…”

PURPOSE: Excellent vision is essential to performing well in sports. Sports vision includes visual, perceptual, cognitive, and oculomotor tasks that enable athletes to process and respond to what is seen. We aimed to examined how sports vision parameters – dynamic visual acuity (DVA), eye movement (EM), peripheral vision (PV), and momentary vision (MV) – varied with age and sex and assessed how static visual acuity (SVA) affect sports vision performance. MATERIALS AND METHODS: Sports vision was assessed at 45 cm distance at best-corrected SVA in 310 nonathletic participants (age, 6–60 years). Among these 310 participants, 108 university students underwent their sports vision test at 45 cm and 2.5 m distance, with and without glasses. The 4 sports vision parameters were measured by Athlevision software package installed to a laptop. Two-way analysis of variance (ANOVA) was used to compare sports vision performance in relation to age group and sex. Repeated-measures ANOVA with 1 within-factor (4 conditions) were used to analyze how sports vision varied among the near/far distance with/without glasses conditions. RESULTS: DVA increased during childhood, peaked during the 20s or 30s, and gradually decreased during middle age ( P < 0.0001). DVA was significantly better in males than in females ( P = 0.0001). The other 3 sport vision parameters – EM, PV, and MV – exhibited similar age trends ( P < 0.001) but did not differ between two sexes. The university students with mild myopia had similar DVA, EM, and PV at both near and far distances, with and without correction; but moderate or severe myopic students with uncorrected vision had worse DVA, EM, and PV at 2.5 m than at 45 cm. CONCLUSION: Low SVA in uncorrected myopia significantly interferes the performance in sport vision tests applied in this study, especially in far distance. Improve static vision, such as myopic correction, may significantly improve sports vision, which is important in athletic performance and safety.

Purpose: To determine whether the distance between objects and the size of object are factors to be able to affect dynamic stereoacuity. Methods: Subjects were 37 adults (26 males and 11 females) with an average age of 23.89±1.76. Refractive error was fully corrected for all subjects and each visual acuity of them was over 0.9. Three rods test was performed for measurement of stereoacuity. The viewing angles from left rod to right rod were set 5°, 10°, and 15° and the rod thickness used 7 mm, 14 mm, and 21 mm, respectively. Stereoacuity was repeatedly measured three times in each test condition at 2.5 m distance, and reported the average value of them. Results: When rod thickness was 7 mm or 14 mm, dynamic stereoacuity decreased as the viewing angle increased, and they were significantly decreased (p<0.01) at viewing angles of 10° and 15° as compared with that of at 5°, respectively. When rod thickness was 21 mm, dynamic stereoacuity decreased as the viewing angle increased, especially, that of at 15°decreased significantly (p<0.01) as compared with that of at 5°. The dynamic stereoacuity depending on the rod thickness have an increasing tendency as the rod thickness increased. Conclusions: The viewing angle between objects and the size of viewing object were factors that affect to dynamic stereoacuity.
