Ask HN: Do you want special glasses for coders?

Hello HNers. I'm thinking to do a little business to sell glasses relieving computer eye strain for under $50. But, I'm not sure if there is the enough demand for them.

So, I'd like to ask you if you want them or not. Saying just Yes or No will really helps me :)
