Co2 Fractional Laser under eyes WITHOUT eye protection. Any suggestions?

I had this procedure this afternoon, and despite asking for eye protection several times, was told by the technician that the laser did not go deep enough to cause eye injury, and to close my eyes. Trusting that the information given by someone allegedly qualified to give it correct. My eyes watered copiously for several minutes following the procedure, and the whites turned pink. I am very anxious and worried that they may have been damaged and I will lose my sight. Please advise. Thanks.
