They might not work on wrap-around lenses.
Two issues<br />1.  Despite being very careful and following the directions closely, there still appeared to be water trapped between the stick-on lens and my sunglasses’ lenses. The “wet” area never dried up or disappeared. No big deal-only I could see it.<br />2.  After 3 or 4 weeks, the stick on lens fell off.<br />Conclusion:  I suspect that the real problem was that the curvature of my sunglasses’ lenses were greater than that of the stick-on lenses, preventing a good seal. The “wet” spot that I saw might have been an air gap.
