Dry eyes and RF?

Testing the ferrite rod antenna on TX this evening (with lots of RF within a metre of me) I'm noticing something I used to get when testing VHF RF PAs years ago in my design days: dry eyes. I assume this is an effect of RF on the body.  Apart from being madder than ever (!) I cannot say RF exposure has done me any noticable harm, but wonder if others have noticed this dry eyes effect?

Although the evidence in general is not strong, there was strong correlation back in my Pye Telecom days between those working on the design of high powered HF/VHF/UHF PA devices and those fathering girls. Maybe there was some subtle damage to sperm with exposure to high RF that made girl pregnancies more likely to succeed? Co-incidence?

A lot more controlled tests are needed, but with the widespread exposure to Wi-Fi and mobile phones it won't be too long before we find out more. So far the evidence is not at all conclusive but you do wonder whether, like smoking, we'll look back in 50 years time and say, did they really all use mobile phones and Wi-fi devices?
