Microwave radiation reported to affect function of the lens
The authors of a recent study reported that lenses from the excised eyes of calves showed functional and microscopic changes when exposed to microwaves at 1.1 GHz and 2mW for 8 days. The functional changes appeared after 48 hours of exposure, and tended to recover after the exposure ceased.
