please only look at the top image in that link. the bottom image is of a type of cataract, which does not apply in this case.
if this is what your husband's bubble looks like, he's right its no big deal.
a pinguecula is a clear-to-yellow lesion on the surface of the bulbar conjunctiva, usually from long term UV exposure. it is not cancerous, it is not dangerous. it can be surgically removed if:
1) it is cosmetically bothersome
2) if it is causing foreign body sensation (feels liks something is in there)
3) if it grows over onto the cornea and impedes or affects vision. if this is the case, we no longer call it a 'pinguecula', we start calling it a 'pterygium':
Many thanks for your clear and precise description. I am quite sure now, particularly after seeing the attached url with the photo of same, which matches identically the lesion in my husband's eye, that it is a pinquecula as you suggest, especially as he is an ardent sunbather. (Over many years I have struggled to get him to use suncreams, he sun-bathes until he is burnt, then sheds skin for weeks! - and does not wear sunglasses a lot of the time.)
I will endeavour to get him to see an optometrist at the very least.
