A really great product.. easy to install I had to trim the lens some but other than that works perfectly.

Just what I needed
After making a couple of adjustments (sizing ) my serengeti sunglasses are now perfect. Allowing me to read my flying charts without having to switch to my readers.

These work ok but are on the thick side, so they look kind of bad. If you cut them, any imperfections in your cut will be very obvious so you're better using a sharp knife and cut them on a board. Otherwise they work ok.

These things are great
I already have a pair of 1.5x lenses on my regular sun glasses which work great for normal use. I just added a pair of 2.5x lenses to a new pair of polarized sun glasses so I would have the additional magnification to tie knots in fishing line for a recent fishing trip. The lenses worked perfectly. Having the extra magnification for working with the small fishing line was awesome.

rewriting my review.... ok now i'm happy
sorry my bad...turns out the magic number for me at least is .25 less than my regular reading glasses. i think it may be the sharp curve of the lens i applied them to. so 1.75 is perfect. i like these because i ruin at least one pair of sunglasses per month offshore boating. now i can buy cheaper sunglasses and swap these inserts to the new pair.

Just what the eye doctor would order?
If fact he did. After my annual checkup I described the need for safety and/or off-the rack sunglasses put needing close in vision correction. Dr. told me which magnification was best for me and I got two pairs. And both work great. Clean the glasses, wet them down, stick on. Good to go. Not a permanent fix for a vision problem as prescription glasses but a great option when for price/style/available you still need to see.

I have wanted some of these for a couple of years now but they were always out of stock. They are wonderful for my collegiate sunglasses that are not available in readers!

These stick-on readers are a great option for use on high end sunglasses. I have used these in the past and will say that they do not replace real readers but work well for reading maps, dashboard gauges, etc. I use these on Persol and Costa glass lens sunglasses without a problem.Service from readingglasses.com is excellent!
