Objective: To assess indicative trends in the use of protective eyewear by Australian squash players and their attitudes towards its use since 1989.

Methods: Data were extracted from three Australian surveys of squash players conducted in 1989, 1995, and 2000. Responses to directly similar attitudinal questions relating to protective eyewear use from each survey were compared. The proportion of players giving each response was calculated for each survey, along with 95% confidence intervals for the differences between the 2000 survey and those from the earlier surveys.

Results: Self reported use of protective eyewear ranged from 10.0% in 1989, to 8.6% in 1995, and 18.8% in 2000. However, only 8.9% of the players surveyed in 2000 actually wore appropriate standards approved/polycarbonate lens eyewear. This can be compared with 8.0% and 2.0% of players who reported wearing appropriate polycarbonate lens eyewear in the 1989 and 1995 surveys respectively. Compared with the 1995 survey, significantly more players in 2000 believed that more players should wear protective eyewear (95% confidence interval (CI) for difference 1 to 18). A significantly higher proportion of players also supported the compulsory use of protective eyewear by juniors in 2000 than in both 1989 (95% CI for difference 6 to 24) and 1995 (95% CI for difference 5 to 22). No other attitudes had significantly changed over the decade.

Conclusion: These data suggest that self reported use of protective eyewear has probably increased over the past decade. However, many players report wearing inappropriate eyewear. A transition from positive attitudes to appropriate eyewear behaviours is required before mandatory protective eyewear use can be effectively introduced.

Statistics from

Squash is a popular sport, with about 15 million players in 135 nations participating annually on 52 575 courts.1,2 It has been shown to be one of the sports most commonly associated with eye injuries, accounting for 7.0–49.0% of all sporting eye injuries, depending on the source of the injury data.3–8 Reported eye injury incidence ranges from 3.7 to 33.3 per 100 000 playing sessions.3,9–12 The most recent Australian study reported 64 eye injuries per 100 000 squash participants.13 Although most eye injuries are not severe, they have the potential to cause permanent visual impairment.8,13,14

Eye injuries in sports are almost completely preventable with standards approved polycarbonate protective eyewear.8,15,16 However, a number of studies have shown that only 9–10% of squash players choose to wear protective eyewear.6,11,17,18 Some players report wearing eyewear that is either not protective or that is actually risk enhancing, such as lensless eyewear, prescription glasses, industrial eyewear, and contact lenses.5,13,19–21 It has been suggested that prevailing attitudes towards protective equipment are a major influence of protective equipment behaviours.22,23

To date, there have only been four published studies, two Australian11,17 and two British6,18, investigating players’ self reported eyewear behaviour. Three of these studies also reported players’ attitudes towards protective eyewear use.6,11,17 A third Australian study has recently been conducted.24 Consistently, these studies have found few adult players to be supportive of compulsory protective eyewear, but many believe it should be compulsory for junior players.6,11,17,24

Since 1989, three surveys of squash players’ attitudes towards, and use of, protective eyewear have been conducted in Australia. Protective eyewear was made compulsory for junior and doubles players throughout Australia in 1997. Since this regulation was introduced, there have been no concerted efforts to further promote protective eyewear use. In the absence of such efforts, especially concentrated on the adult population who are not the target of this regulation, it could be expected that there would be no substantial change in rates of protective eyewear use by squash players. The aim of this study was to describe the indicative trends in protective eyewear use and attitudes towards such use, to see if this was, indeed, the case.


A search of the literature specific to squash players’ protective eyewear behaviours and associated attitudes towards its use was conducted. Three studies, all Australian, conducted in 1989,11 1995,17 and 200024 were identified as having similar methodologies and survey questionnaires. Table 1 describes the key methodological methods used in each of these studies. Although the studies were conducted in different Australian states, and different sampling frames were used, they asked similar questions about player attitudes.

Methodology comparisons between three Australian studies of players’ attitudes towards the use of protective eyewear

The numbers and percentages of squash players responding to behavioural and attitudinal questions relating to protective eyewear use was extracted from each of the published studies and compared. For each study, protective eyewear rates during squash were determined from players’ self reports. Information about the type of eyewear used was also obtained, and the reported eyewear was categorised as “appropriate” or “inappropriate”. Appropriate eyewear was defined as polycarbonate lens/standards approved squash eyewear. As no other eyewear is suitably protective,5,13,19–21 all other eyewear was classified as inappropriate.

In each of the three studies, players were asked to report their attitudes towards four or five statements about protective eyewear use on a five point Likert scale (strongly agree, agree, uncertain, disagree, strongly disagree) (table 2). The wording of three of the statements was exactly the same in all surveys. Players’ attitudes towards one identically worded statement were available for the 1995 and 2000 studies only. The remaining statement, although having the same meaning in all studies, was worded: “protective eyewear should be made compulsory” in the 198911 and 199517 studies. In the 2000 study, the words “for all players” were included at the end of this statement.

For comparative purposes, responses in the “strongly agree” and “agree” categories were combined, as was the data in the “strongly disagree” and “disagree” categories. For four of the attitudinal questions the “strongly agree/agree” response was the most desirable (table 2). For the remaining question, the “strongly disagree/disagree” response was most desirable (table 2). Ninety five percent confidence intervals were calculated for the differences in attitudes from the 2000 survey and earlier surveys.25 A confidence interval containing the value “0” was taken to indicate no significant difference between the comparison surveys.


Protective eyewear behaviours

Figure 1 summarises the rates of protective eyewear wearing in the three studies. Over the 11 year period, self reported protective eyewear use changed from 10% in 1989 to 8.6% in 1995, then increased to 18.8% in 2000. However, the rate of self reported use of inappropriate eyewear also increased over time. Nevertheless, levels of appropriate protective eyewear use were highest in the most recent survey.

Attitudes towards protective eyewear use

Table 2 presents a comparison of players’ attitudes across the three studies. Overall, this suggests that there have not been major changes in players’ attitudes towards the risk of eye injuries since 1989. There was a slight, but non-significant, increase in players’ positive responses to the statement that eye injuries are a particular problem in squash, from 1995 to 2000, with comparison data not available from the 1989 survey. In the 2000 survey, significantly more support for general protective eyewear use was given with 67.0% of players stating that they believed more players should use protective eyewear, compared with only 57.0% of players in 1995. There was no significant difference between the 2000 and 1989 survey responses to this attitudinal statement.

The extent of players’ positive views towards the implementation of compulsory use of protective eyewear for all players ranged from 17.0% of all surveyed players in 1989 and 16.0% in 1995 to 24.0% in 2000. However, this increase was not significant. Although most players in 2000 did not support compulsory protective eyewear for all players, a high proportion (69.0%) were in favour of it for junior players. There was a significantly higher level of support for junior eyewear use in 2000, compared with both earlier surveys. Most players in each study indicated that they would not stop playing squash if protective eyewear was made compulsory, and this attitude did not vary significantly across the studies.


Before compulsory use of any form of protective equipment can be effectively implemented, efforts need to be made to address player attitudes and how these have changed over time.26 If voluntary use of protective equipment among players is not at an acceptable level before the introduction of a regulation requiring its use, then in the absence of strong penalties and regulatory monitoring, its introduction is unlikely to be successful as there will be little support for it. As has been shown with the introduction of mandatory bicycle helmets, a broad level of acceptance for protective equipment is essential before mandatory use can be successful.26 For example, voluntary use of bicycle helmets in Victoria, Australia was raised to 36% before mandatory legislation.26 Attention should therefore be given towards player education about protective equipment use before a regulation is introduced. Identification of player attitudes towards such equipment is necessary to guide this process.

This study has compared indicative results from three Australian studies, which surveyed squash player behaviours and attitudes associated with protective eyewear use. It is recognised that there are limitations associated with these comparisons, as the studies did not all have consistent methodology. For example, the 1989 survey included only competition players. Players with more squash experience are significantly more likely to report playing with protective eyewear, than those players with less experience.24 Whereas only adult players participated in the 2000 survey, there was a small proportion of junior players in the 1995 survey, and the age distribution of players from the 1989 survey was not reported, although it was probably mainly adults. The 1995 survey relied on a volunteer sample of players and this may have led to a biased sample, as players that wore protective eyewear may have been more inclined to participate in the survey. Alternatively, it could be that the method of player recruitment in the 1995 study was so different from that in the other studies that it influenced the results. Given these limitations, it is possible that the reported rates of eyewear use in the two earlier surveys were overestimated. However, it is unlikely that this would have led to a differential bias in the reporting of appropriate versus inappropriate eyewear use. The information available did not allow a direct comparison of player characteristics across surveys to be made. It should also be pointed out that each survey potentially excluded any player who was absent because of an eye injury at the time of the survey.

Overall, the indicative trends presented in this paper suggest that self reported voluntary protective eyewear use has nearly doubled since 1989. There was no a priori expectation that rates of protective eyewear use would have changed over the past decade, as there has been no active promotion of protective eyewear throughout this period in adult players. However, the high, and apparently increasing, proportion of players reporting inappropriate eyewear use is a concern. Squash standards approved polycarbonate lens eyewear is the only eyewear that provides suitable protection. All other eyewear reported has been shown to potentially heighten the risk of ocular damage.6,13,27

A comparison of the attitudes reported in these three Australian squash player surveys suggests an encouraging change in players’ attitudes towards the implementation of compulsory protective eyewear for junior players. However, the proportion of players favouring compulsory protective eyewear for all players is much lower than that supporting use of such equipment by junior players. The compulsory use of protective eyewear for junior players introduced in 1997 in Australia16 may have contributed to these trends.

Use of protective eyewear while playing squash is compulsory at many clubs in certain states and provinces in the United States of America and Canada.28 However, its use is not as yet mandatory for Australian adult players, nor for players from the United Kingdom or Europe.16 The implementation of mandatory protective eyewear use in parts of the United States of America was reportedly met with minimal player resistance and has eliminated the occurrence of most eye injuries caused by squash.13

It is expected that, if protective eyewear use was made compulsory for adult squash players in Australia, the occurrence of eye injuries in squash would subsequently be minimised. Ideally, future strategies for eye injury prevention in squash will assist players in the transition to appropriate protective eyewear use and their acceptance of this behaviour change. It is possible that, if protective eyewear is made compulsory for all players before, or without, a coincident increase in knowledge about the risks of injury and what is appropriate eyewear, then there may not be high compliance with this ruling.24,29 Nonetheless, it is likely that managers of squash venues would support this regulation and not risk litigation from injured players.

In summary, this study has found that many players do not wear suitable protective eyewear when playing squash. Indicative trends suggest an increasing proportion who report wearing protective eyewear, but a large number of players actually using inappropriate eyewear. A lack of knowledge about the risks of eye injury and of what eyewear is suitably protective may contribute to the low rates of protective eyewear use. However, there is also a suggestion that players’ attitudes do not currently support widespread mandatory protective eyewear for all players. It is recommended that the results of this study be considered by squash bodies, eyewear manufacturers, venue managers, and players associations for the development of eye injury prevention strategies for this sport. Future research is required to explore strategies to enhance protective eyewear through squash venues, as well the best ways to educate players of the risk of eye injury and of appropriate eyewear for the game of squash.

Take home message

It is important to understand the attitudes of squash players towards protective eyewear before its use is made compulsory. Many players do not wear appropriate eyewear when playing. Education strategies are required to increase the use of appropriate protective eyewear, while decreasing the use of inappropriate eyewear.


Mr Paul Vear, the Executive Director of the Victorian Squash Federation, is thanked for his support of this project.
