Have you seen the nasty looking glasses that blind people wear? And that cane really sucks too. Sorry for not being PC.
In other words "How much are your eyes worth to you"? I need mine to earn my living every day and never go outside (daytime) without a pair of sunglasses of some sort. This is also under recommendation of my Opthalmologist, even if there is cloud cover. They're your eyes, protect them or damage them, your choice.
