I used to have to wear those adhesive ones over my right eye to try and make my left eye stronger.
The adhesive smelled like shit and would make me sick feeling (not to mention the'd pull your freaking eyebrow hairs out) so I'd flush about a pack of them a day down the toiled and my mom would be like, "wear'd they all go?"
And I'd be like, "they only come in packs of five!"
Then I'd be grounded.
Gradauted to the strap patch then just got glasses. None of it really helped.
