A company that wants to provide online eye examinations is suing South Carolina after the legislature overwhelmingly voted to ban the practice in the state.

The suit, filed in the South Carolina Court of Common Pleas, accuses lawmakers of siding with traditional storefront businesses to stifle telemedicine that benefits consumers.

Chicago-based Opternative, backed by the Virginia-based Institute for Justice (IJ), litigates on behalf of others to limit the scope of government. It wants the courts to overturn the ban.
