“…These phenomena can be relieved by the use of contact lenses in water (Itagaki et al, 1994). Further, Komori et al (1998) reported that the use of contact lenses helped to prevent corneal and conjunctival epithelial damage and the impairment of visual function during water-polo play. Considering both visual function and protected ocular surface epithelial damage, it is effective for water-polo players to use contact lenses in water.…”

This study investigated the extent of contact-lens use in Japanese college water-polo male players over 20 years (1991-2011, once every five years). Information about the use of contact lenses during play and the types of contact lens was obtained through a self-report questionnaire. The proportion of contact lens use among the players while playing water polo differed from 1991 to 2011 (χ2(4) = 25.28, P < 0.001, Cohen's d = 0.63). Fifty-four per cent of the players used contact lenses while playing in 1991 (P < 0.001); more than 74% in 1996; 89% in 2001; 84% in 2006; and 86% in 2011. While 96% of the contact lenses used by the players in 1991 were the soft type, 74%, 92%, 86%, and 88% of the contact lenses used in 1996, 2001, 2006, and 2011, respectively, were the disposable type. These findings indicated a high percentage of players were using contact lenses while playing water polo between 1996 and 2011. This could be because the majority of players used disposable lenses. The results suggest that increasing use of contact lenses by water-polo players is beneficial.

This study examined the effects of the use of contact lenses on static and kinetic visual acuity, ocular pain, and blurred vision during a water polo match. Eleven male water polo players participated in this study, and were assigned to one of two groups: contact lens users (CL, n=5） and non-users (NCL, n=5）. Both groups participated in a typical water polo match with four 7-min periods and 2-min resting intervals between the four periods. Static and kinetic visual acuity, subjective ocular pain, and blurred vision were measured before the match (pre-test）, during the match (after each of four 7-min periods）, and during the recovery phase at 5, 15, and 30 min after the completion of the match. Results showed that kinetic visual acuity was significantly lower for the NCL group than for CL in the 4 th period of the match. In addition, for the NCL group, kinetic visual acuity was significantly lower in the 3 rd and the 4 th periods than at the pre-test time. On the other hand, static visual acuity did not significantly differ between the two groups; but, for NCL, static visual acuity was significantly lower in the 4 th period than at the pre-test time. According to self-evaluation scores, ocular pain significantly increased in NCL compared to CL in the 3 rd and 4 th periods. Ocular pain in NCL was significantly higher between the 2 nd period and recovery phase at 5 min than at the pre-test time. Blurred vision was significantly higher in NCL than CL between the 2 nd period and recovery phase at 5 min. Blurred vision in NCL was significantly higher at the same duration than at the pre-test time. These findings indicate that the use of contact lenses may prevent ocular pain and blurred vision, maintaining both the static and kinetic visual acuity at a normal level during a water polo match. Further, the results of this study suggest that the use of contact lenses is effective for water polo players.(Jpn. J. Phys. Fitness Sports Med. 2011, 60：113-120）
