Help I am wearing purple sunnies

This is how well I see nowadays without glasses. The world is a lovely place!  It's blurry and everything looks pretty flawless. And then last week I saw these brown Ray Bans and having just lost my 15-year old aviators I thought I should go for something different and fresh. So I bought the brown Ray Bans.

So then why are the damn things PURPLE RAINBOW SURPRISE????????????????????? Eye check up imminent.
