Sen. Charles Schumer, seeing red over the high prices of eyeglasses, demanded Sunday that federal authorities make it easier for consumers to shop for better deals.

The Brooklyn Democrat wants the Federal Trade Commission to require optometrists to issue easy-to-carry, full prescription data so patients can test the market.

“The average price of a new pair is $300, and it keeps going up,” the bespectacled Schumer said outside a Midtown Lenscrafters store. “When an iPad costs less than a pair of glasses, something’s wrong.”

Increasing competition is the only way consumers can score better deals, Schumer insisted.

“The eyeglasses market is broken, and consumers bear the cost of that,” Schumer said.

“If you want to get your lenses from somewhere else than where you got your prescription, that shouldn’t be made difficult.”
