Eye hazards of airborne radar
J. G. DAUBS, O.D. · 1969
1969 radar eye hazard research provided early evidence of microwave biological effects, relevant to today's close-proximity device use.
Plain English Summary
This 1969 study examined potential eye hazards from airborne radar systems, focusing on microwave radiation exposure risks for aviation personnel. The research addressed growing concerns about radar operators and aircrew experiencing eye damage from microwave emissions during the early radar technology era.
Why This Matters
This early research represents a crucial moment in recognizing occupational EMF hazards, decades before consumer wireless devices became ubiquitous. Aviation radar systems of the 1960s operated at similar microwave frequencies to today's cell phones and WiFi, but at much higher power levels. What makes this study particularly relevant is that it documented real-world occupational exposures that helped establish the biological basis for current EMF safety standards. The reality is that radar operators were essentially early test subjects for microwave exposure effects. While modern consumer devices operate at lower power levels, they expose billions of people continuously rather than occupationally. The eye remains one of the most vulnerable organs to microwave radiation due to limited blood flow for heat dissipation, making this historical research directly applicable to understanding risks from prolonged smartphone and tablet use held close to the face.

The eye hazards of airborne radar, particularly low-power airborne weather radars, are significant and often underestimated. While the MSEL of 10mw/cm² is widely accepted, it may not necessarily insure safety as heating effects may not be the only source of ocular damage. Other possible effects not related to increased temperature are chemical changes in protein molecules resulting from high peak powers at short pulse widths. Prevention is of utmost importance since these changes are irreversible. The study recommends that optometrists educate patients working near radar equipment, monitor work areas, and perform thorough examinations of exposed patients.
