The Reagan administration, rejecting the controversial suggestion of sunglasses and tanning lotion as protection against ultraviolet radiation, has decided to maintain its call for strong international controls on chlorofluorocarbons to protect the Earth's atmospheric ozone, officials said Thursday.

At an international meeting this week in Brussels, U.S. negotiators reaffirmed support for a tentative agreement among 31 nations to freeze production of chlorofluorocarbons at current levels and cut their use by 20 percent over the next decade, officials said.

The agreement, reached in April, had been applauded as an important step in stopping depletion of ozone, which blocks most of the sun's harmful ultraviolet rays and helps prevent skin cancer.

But opposition to the proposed pact began surfacing in the administration among officials concerned that it flouted President Reagan's preference for limited government regulation. Interior Secretary Donald Hodel reportedly argued at a meeting of the Cabinet Council on Domestic Policy for an alternative program of "personal protection," including hats, sunglasses and skin lotion.

Hodel, whose idea was ridiculed by environmentalists, said later that he did not advocate the program but wanted to present options to Reagan.

"The secretary succeeded in getting options to the president so he could issue guidelines to negotiators," a Hodel spokesman said.
