According to a famous optical expert, Alexander, who recently visited Shanghai, the developed countries in Europe and America have made rules that children must wear resinous glasses instead of the traditional glasses made of glass. This is because the glass glasses are more likely to do harm to children’s eyesight.
Alexander pointed out, wearing the right glasses as soon as possible is still the best way to cure and put right children’s eyesight problems.
In America and Japan the resinous glasses have taken up 80 percent of the glasses market. And some European countries and America have made it a law that children, teenagers and drivers must wear resinous glasses. Now, about 10 million children in China have different eyesight problems and they need timely treatment.
But still, too many parents are buying the traditional glass glasses for their children. This is mainly because many parents know little or nothing about the good points of the resinous glasses. Besides, the price for the new glasses is a little higher than the traditional ones.

According to Alexander, the "timely treatment" to eyesight problems is ______.

A．to stop wearing glass glasses any more

B．to buy a pair of glasses and wear them right away

C．to wear suitable resinous glasses at the right time

D．to buy glasses made in Europe, Japan or America if possible
