Trauma still constitutes one of the leading causes of blindness.1 Although safety programs are almost universally enforced in industry, there is often laxity at home where many eye hazards exist. With the widespread use of power lawn mowers, a relatively new eye hazard has become apparent.2 Scattered throughout a lawn, many nuisance objects such as stones, pieces of glass, or metal may be transformed from innocuous bits of waste into dangerous missiles. These objects are picked up by rotary cutting blades (turning at the rate of 2,000 to 4,000 rpm) and become high speed projectiles, often traveling more than 50 ft. Although any part of the body of an innocent bystander might be affected, the danger of loss of vision is very high when an eye is struck.
Five cases of eye injuries secondary to power lawn mowers have been seen in our office since September, 1955. It
