Hi there fellow grasshoppers,

I know this might be a silly and perhaps a basic kind of question. Having read on the internet that pilots apparently are at more risk of certain eye problems such as cataracts (if this is debatable feel free to tell me so, I am not saying this like I am an expert on the field), is it perhaps possible to conclude that people who fly very frequently as passengers are also subject to similar health risks regarding the eyes?

I've been thinking about this lately because my dad, who has been flying at a frequency at about once every month or two for the past several years, recently developed cataracts. He asked me whether it could be because of flying so much, but all I told him was that I could only say it sounded possible but I didn't go beyond that, since I wasn't really sure about myself. I also have been thinking about looking for a job as a flight attendant for maybe a year when I finish college a couple of years down the road, so I definitely would like to know whether or not there is evidence or whether frequent flying has been proven with being connected to greater risks of eye problems?

Thanks in advance,
