Lexington, Massachusetts Abstract. Sports-related eye injuries pose a substantial and preventable problem. Ophthalmologists, by educating their patients regarding the risks of eye injuries in various sports and the benefits and availability of protective equipment, have the potential to prevent injury to well over 100,000 eyes each year. General guidelines and recommended levels of eye protection for various sports are given. The appendix lists suppliers of protective equipment. (Surv Ophthalmol 2547-51, 1980) Key words.

phthalmology, as a discipline, has neglected a major cause of blindness sports eye injuries. The average ophthalmologist sees over fifty patients with sports eye injuries for each new melanoma (see footnote on next page) yet the literature and funds research overwhelmingly emphasize the rarer diseases. Why? Perhaps because, as ophthalmologists, we are trained to treat disease, we feel more comfortable with diseased eyes than with healthy eyes that only have the potential of pathology. Somehow, the discussion of injury prevention makes many of us “surgeons and healers” feel like technicians. However, as primary eye care providers, our responsibility in this area cannot be denied. Table 1 hints at the magnitude of the problem of sports-related eye injuries. Truer estimates would be obtained by multiplying

more patients present to private offices than to hospital emergency rooms. The National Society to Prevent Blindness estimates that 90% of the sports-related eye injuries are preventable. The widespread mandatory use of hockey face masks has prevented over 70,000 projected eye and face injuries in the 1,200,OOOprotected players at an estimated savings to society of over $lO,OOO,OOO last year alone. Ophthalmologists are urged to take a more active leadership role in injury prevention. Communities rightly expect their ophthalmologists to have answers to questions on injury prevention and, by educating our patients regarding the risks of eye injuries in various sports and the benefits and availability of protective equipment, we have the potential ability to prevent injury to well 47

Observations
(1) Hockey injuries are decreasing as a result of protective facemasks. (2) Although hockey injuries have decreased dramatically to players wearing face protection, a significant injury problem remains for unprotected players. (3) There is an upward trend of injuries in baseball, basketball, and football. (4) Injuries from airguns and cycling continue at a steady rate. (5) There is steady increase in sports-related eye injuries. Source: Unpublished data from the Consumer Product Safety Commission provided to the Operational Research Department, National Society to Prevent Blindness, New York. *“.50 patients with sports eye injuries for each new melanoma.” (see page 47)
This statistic was gathered from two sources: (1) the relative incidence of sports eye injuries to melanomas that we see in a large private practice of fulltime ophthalmologists, and (2) extrapolation from national data as follows. The incidence of melanoma has been estimated at 0.6/100,000 or approximately 1200 new cases per year.’ The National Society for Prevention of Blindness estimates that over 100,000 eye injuries result from play or sports to school-age children alone. The totals from the Consumer Products Safety Commission of over 26,000 eye injuries from selected sports in 1978 probably reflects approximately 25% of the total eye injuries which actually occur. This low estimate of injuries by their data collecting system is due to the fact that they extrapolate data from visits to emergency rooms and do not gather data from visits to private offices. They also collect data concerning product-related injuries and might not necessarily collect all athletic injury data. If it is conservatively estimated that the actual athletic eye injury rate lies somewhere between the Consumer Product Safety Commission estimates and those of the National Society for Prevention, a reasonable figure of 60,000 eye injuries from sports could be presented. This figure is fifty times the incidence of new melanomas, and this is consistent with our office experience.
over 100,000 eyes each year.
General Guidelines Table 2 outlines the various recommended levels of protection, and the appendix provides a listing of manufacturers and suppliers of protective equipment. The following are general guidelines which cover most sports and most participants in these sports. Of course, these guidelines, as well as the recommended levels of protection, should be modified as new data and standards are developed. HELMETS Sports which involve high speed collisions with other players, sticks or immobile objects (football, hockey, lacrosse) require that eye protection be considered in the concept of
head protection. Absorbed energy must be transmitted through a facemask into a helmet specifically designed to dissipate the energy and prevent brain injury. Standards are available for motorcycle helmets, football helmets, hockey helmets and hockey facemasks, but are lacking in other important total

areas (football facemasks, horseback riding helmets, lacrosse helmets and facemasks, baseball helmets and most other “protective devices”). INDUSTRIAL SAFETY SPECTACLES
As a general rule, athletes participating in sports which involve a ball, racket, poking fingers, fists or elbows (basketball, racket sports, baseball, etc.) could obtain adequate protection with industrial safety spectacles (ANSI Z 87.1). Clear sideshields provide protection to the exposed lateral side of the eye. Plastic (polycarbonate or CR 39) are lighter and stronger than hardened glass. Players who ordinarily wear spectacles could have their prescriptions made in plastic industrial safety lenses and mounted in industrial safety frames (many suppliers),
sports frames (CRISS, American Optical) or injection molded polycarbonate frames (through opticians). Players who ordinarily do not wear spectacles could achieve protection with plano polycarbonate industrial lenses or injection molded piano’ polycarbonate eye protectors (Pro-Tee). For the racket sports, lensless eye protectors of polycarbonate (Pro-Tee) or wire (Champion) are available. STREETWEAR SPECTACLES
Streetwear spectacles with plastic lenses offer adequate but not complete protection for tennis and badminton, but not for squash and racketball which require the strength of the industrial ANSI Z 87.1 standard. Glass streetwear spectacles are not

recommended for athletes. They are heavier than plastic, shatter more easily and have lacerated several eyes, especially in squash players. Industrial strength glass lenses have a greater tendency to shatter than their plastic counterparts and are so heavy they tend to fly off the face with rapid starts and stops. OTHER CONSIDERATIONS
Contact lenses offer no eye protection whatsoever. A practitioner would be negligent to fit an athlete with contact lenses and not advise the athlete that there now exists a greater risk of injury. Contact lens wearers should have the same level of protection advised for players who ordinarily do not wear spectacles. Divers should have their spectacle prescriptions bonded to the inner surface of high quality diving masks. Contact lenses are not advised as loss of the lens under water (which happens easily if the mask leaks just a little) could result in loss of orientation for the highly myopic or hyperopic diver. One-eyed children should wear safety glasses at all times. They should not play contact or collision sports. If for psychiatric reasons, participation is required, then for hockey, football, field hockey, lacrosse, etc., safety glasses should be worn beneath the helmet-facemask combination. A fine mesh wire hockey face shield should be substituted for the bar type football facemask.
