Very difficult to see the signature. Oakley did a ton of custom signature lenses for their athletes back in the day. Probably more than even the number of custom microbags they put out nowadays. Most of those that have hit the collector market are motorsports-based athletes. Your pair is likely one of those. Or it may be a collector did a custom using his/her own laser, since some have figured that secret out. Tough to say. - Oak
It looks like Gary Scalzi from the shape, but yes a better pic would definitely help...
