It always comes back to that central issue.

After years of having no pair of glasses to complement my contacts, my wife finally got me to get a pair of glasses back in the summer. Why did I finally give in? Mainly because I finally got sick of people asking how high I was. Note the crystal clear eyes behind those glasses? OH WAIT - I must be on some other type of drug that whitens your eyes. That can really be the only answer, right? Occam's Drug Razor, right?
