These glasses most likely date to 2004/ 2005  as there was an appointment card for 9/23/05 in the case when purchased.   I found no indication as to their strength, they seem strong, but I don't wear readers so have really no way to compare.  Perhaps they could even be custom.  Condition is pre-owned and perhaps worn but they maintain an original pricing tag.  There was also a small Brighton promotional pamphlet for sunglasses.   The case has some light scratches and a small dent.   Enlarge and look at all photos for more details on condition and design.  Please contact if additional information or photos are needed.
