A LENS OPACITY WITH THE MORPHOLOGICAL FEATURES OF SMELTING CATARACT IN A WELDOR
Szafran · 1965
This 1965 welding case documented how occupational electromagnetic radiation exposure can cause cumulative eye damage over time.
Plain English Summary
This 1965 case study documented a welder who developed a specific type of cataract (lens opacity) with characteristics similar to those seen in metal smelting workers. The research examined how occupational exposure to infrared radiation from welding operations can damage the eye's lens, contributing to early understanding of radiation-induced cataracts in industrial workers.
Why This Matters
This early occupational health case represents a crucial piece of the electromagnetic radiation puzzle that often gets overlooked in today's EMF discussions. While we focus heavily on radiofrequency radiation from phones and WiFi, this 1965 study reminds us that the electromagnetic spectrum includes infrared radiation, which has been causing documented health effects in workers for decades. The welding industry's experience with radiation-induced cataracts provides a real-world example of how electromagnetic energy can cause cumulative biological damage over time. What makes this particularly relevant today is that we're seeing similar patterns of gradual, cumulative effects from our daily EMF exposures, just at different frequencies and power levels. The welder's cataract didn't appear overnight - it developed through repeated occupational exposure, much like how modern health concerns around EMF exposure focus on long-term, low-level effects rather than immediate acute symptoms.
Finding
The smelting cataract is a delicate, clypeate opacity. It is situated in the layers of the posterior cortex under the capsule of the lens. The opacities are more delicate than in complex cataracts and they are yellowish (Vogt).

Exposure Information
Specific exposure levels were not quantified in this study. Duration: 26 years of welding, 6 years in high ambient temperature (60-80°C)
Study Details
To report a case of lens opacity with morphological features of smelting cataract in a weldor and discuss the possible influence of infrared radiation exposure.
Case report of a 53-year-old weldor with 26 years of electrical and acetylene welding experience, in...
The patient had a yellowish opacity in the posterior cortex of the lens, with a circular opacity at ...
The case demonstrates that smelting cataract can occur in weldors due to long-term exposure to infrared radiation from welding processes. The morphological features were similar to those described in metallurgical workers. The combined long-term effects of exposure to both long and short wavelength infrared radiation were considered probable.
