OCULAR EFFECTS OF MICROWAVE RADIATION
Milton M. Zaret · 1967
Early research showed rabbit eyes are vulnerable to microwave damage, establishing eye safety concerns that remain relevant today.
Plain English Summary
This 1967 study by Dr. Milton Zaret examined how microwave radiation affects rabbit eyes, specifically investigating lens damage and cataract formation. The research focused on understanding the eye's vulnerability to microwave exposure, which was becoming a growing concern as radar and microwave technologies expanded. This work helped establish early understanding of how electromagnetic radiation can damage delicate eye tissues.
Why This Matters
Dr. Zaret's pioneering research came at a critical time when microwave technology was rapidly expanding, yet safety standards were virtually nonexistent. His work on ocular effects helped establish that the eye is particularly vulnerable to microwave radiation because the lens lacks blood circulation to dissipate heat and repair damage. This research laid important groundwork for understanding EMF health risks that remain relevant today.
What makes this study significant is its early recognition that electromagnetic radiation could cause biological damage beyond simple heating effects. While we've learned much more about EMF mechanisms since 1967, the fundamental concern about eye vulnerability persists with modern devices like cell phones, WiFi routers, and wireless headphones that expose our eyes to similar frequencies daily.
Finding
The experiments conducted at 5400 MC corroborate the previous findings of this investigation performed at 5500 MC. For these two frequencies, the results may be summarized briefly as follows: 1. Acute microwave opacities are directly related to average power density. 2. Time-power relationships for such cataractogenesis can be determined by biological assay. 3. The various microwave emission factors can be segregated and controlled. 4. For the two points in the spectrum so far studied, there is no significant frequency dependent effect.

The experiments conducted at 5400 MC corroborate the previous findings of this investigation performed at 5500 MC. For these two frequencies, the results may be summarized briefly as follows: 1.

The various microwave emission factors can be segregated and controlled. 4, For the two points in the spectrum so far studied, there is no significant frequency dependent effect. The data accumulated to date demonstrate that the technique for irradiation has been firmly established and the results have become predictable. Therefore, it is now desirable to phase in primate experiments for direct extrapolation to man.
