Did your eye doctor prescribe you contact lenses?
No, I'd like to know something about contact lenses.
Oh, I see. We have both hard and soft contact lenses. They are very popular, but a little more expensive than ordinary glasses.
I have found I'm short-sighted recently. I need to wear glasses. As a student, it's better for me to wear ordinary glasses instead of contact lenses.
We have many kinds of glasses here. Which frames do you like best?
I think the square-shaped ones will be the best for me.
What about this pair? They are the'in'things now in optical wear. Try them on.
They fit me very well. I like them.
