TUNA ALLEY READERS is rated 4.7 out of 5 by 42.
Rated 5 out of 5 by from Great Readers These are my 4th set of reader sunglasses. These are pretty awesome! All the others either had too large or too small of magnification area. They really got these right. In the past, I had to carry two sets of sunglasses - one regular and one reader set. These can be worn as your primary sunglasses. The magnification area won't bother you while looking straight ahead.

Rated 5 out of 5 by from Always Exceptional Customer Service Bought these glasses over a year ago, asked that they be repaired. No expectation for warranty. CDM offered to replace them for a nominal fee. For over 15 years I have only worn CDM sunglasses. Exceptional Customer Service keeps me coming back! Sometimes I send in 4-5 pair at a time for repair. Always professional! Wish I could get my staff to perform as consistantly

I want to buy a pair of tuna alley readers in 1.5.  Why can't I have them in the camo?

Asked by: Jtp1
Hi! We have a limited selection of our readers, which is why the Tuna Alley readers are not available in camo.

Would like to know if you can have your prescription put in your lenses. And if so the price. They have a display at my Dr. Office but they don't seem to know enough to answer my questions. I an on my 3rd pair and my eyes are slowly changing.

Asked by: Bcardyman
I am sorry we cannot discuss cost for prescription products as we are not actually making the transaction with you. We have many prescription dealers that can be found using our Dealer Locator ( so you might find a dealer more well versed in our product, or might ask that your doctor's office simply give our Prescription Team a call and they'll be happy to help the account.
