Hey, it's a real shame that some people can't get access to glasses or contact lenses
Why not?
I suppose it's because they're expensive. They're often worn to correct vision but some are cosmetic and even therapeutic
I've never wore contacts before. Is it hard? 
I don't think it's too hard but it might be a bit daunting at first. You just place it directly on the surface of the eye
I've considered getting colored contacts for costumes. Are the similar to contacts for sight?
Yes except they don't correct your vision. I guess they might even hinder them
Ha! I guess you're right. You mentioned contacts are expensive. How much are they?
