In brief: A growing number of eye injuries in squash and racquetball in the late 1970s triggered research on eye protectors for these sports. The investigations showed that lensless eye guards were ineffective and that the frames of some lensed eye guards shattered when hit by a ball. Subsequently, Canadian and US organizations set standards for eye guards, requiring that the devices protect the eye from a ball traveling at 90 mph. Seven commercially available eye guards now meet the Canadian or US standard or both. Polycarbonate is the best lens material for eye guards. There is no substitute for approved eye guards; neither experience nor ordinary prescription glasses nor lensless eye guards provide good protection.
20世纪70年代末，壁球和短柄墙球运动中越来越多的眼部受伤事件引发了针对这些运动护眼用具的研究。调查表明，无镜片护眼罩无效，一些有镜片护眼罩的框架在被球击中时会破碎。随后，加拿大和美国的组织制定了护眼罩标准，要求这些装置能保护眼睛免受时速90英里的球的伤害。目前有七种市面上可买到的护眼罩符合加拿大或美国标准，或两者都符合。聚碳酸酯是制作护眼罩的最佳镜片材料。没有什么能替代经批准的护眼罩；经验、普通处方眼镜或无镜片护眼罩都不能提供良好的保护。
