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 ?
