    I do not agree with your complacency in this matter.
    
    I have seen three retinal holes, two certainly due to looking at the sun 
    through a telscope and I suspect the other was too, though the person denied 
    it.. and I am not looking at pathology cases all day long as in a hospital 
    eye department - only a random sample of people.
    
    Ask any consultant ophthalmologist if they have seen foveal damage due to 
    bright sources and they will concur.
