The title of the page you link to is "Weightlifting Increases Pressure Within The Eye". That is not at all the same thing as it being overall bad for you. The worst thing mentioned in the article is "Prolonged weightlifting could be a potential risk factor for the development or progression of glaucoma (an eye disease)".

I'd have to say that the benefits of weight lifting probably outweigh the slight chance you'll get some form of glacouma.
