Main Street’s eye doctors are calling on President Trump to thwart a burdensome Obama-era rule that could force them to hire more staff and spend potentially $925 million just to give patients the contact lens prescription they are already legally obliged to provide.

In a letter to Trump, who has declared war on Obama regulations, the group representing 50,000 eye doctors said that they are being punished because just a few didn’t follow a 2004 law and give patients a copy of their prescription, which can then be used to buy contacts online.
