Reviews

Nice replacement!

"I had glass lenses prior to but they cracked the plastic stay on way better and don’t fall off my hat ever. They are a different color than the blue Costas so that took some getting use too overall very satisfied"

— Kaleb S. (5/5)

Install

"I had trouble installing the lenses and I scratched one side. I do find that they reflect my own face . I can see my reflection in them. I feel like the original coastal Lenses were better."

— wesley B. (2/5)

Disappointed

"Lenses do not fit into the frames I ordered for."

— megan R. (1/5)

Costa Bloke lenses

"I like the lenses. They actually seem to be a little clearer and brighter than the originals. Only issue was the removal of originals. Difficult to get the old lenses out on this pair. They were very tight in the frames. Be careful not to break the original lenses or the frames. Almost cut my fingers. New lenses went in much easier. Good tight fit in frames. Should hold up nicely."

— RUSSELL C. (4/5)

Not a good fit

"Not same as manufacture. Not glass. One side loose. Makes noise when touching it because not a good fit. Not sure if error when cutting. Other side in tight and fits well."

— Eric M. (2/5)

"Love it"
