What material is used in your lenses?
Our standard 1.59 lenses are made from polycarbonate, which are far thinner and lighter than traditional plastic (CR-39) or glass lenses. Polycarbonate is the most impact-resistant material available and offers 100% UV protection.
For stronger prescriptions or customers wanting thinner lenses, we offer 1.67 polyurethane optical and prescription sun lenses. These are thinner and lighter than our standard lenses.
Don’t plastic lenses scratch?
Our 1.59 polycarbonate and 1.67 polyurethane lenses are ultra durable, but we still add a anti-scratch coating to kick up the protection at no additional cost to you.
Do you offer lens coatings?
All of our optical lenses are coated with a premium anti-reflective “no glare” coating and an anti-scratch coating. We never liked how some doctors and stores make you pay extra for coatings so we included them at no cost to you.
What kind of lenses do you use in your sunglasses?
We are able to add polarized prescription and non-prescription lenses to most of our sunglasses. All of our polarized lenses are 100% UVA/UVB protected and scratch resistant. Polarized lenses cut down on the glare caused by reflected light (from snow, water, or the road). They protect your eyes and help you see clearly. You can select either your non-prescription or prescription polarized lenses on the Try-On page or during checkout. Non-Prescription Polarized or Polarized Single Vision Rx
For most of our sunglasses, we offer the option to add brown, grey, or G15 (green) polarized lenses. We can add non-prescription polarized lenses to most of our sunglasses for $50 and we also offer Polarized Single Rx 1.59 polycarbonate lenses for $80. If your Rx requires thinner lenses, we also offer Polarized Ultrathin Rx 1.67 polyurethane lenses for $169.
DITTO also offers RX Progressive No-Line Bifocal Lenses as an option for your new shades. We offer Polarized Rx Progressive 1.59 polycarbonate No-Line Bifocal lenses for $199 and Polarized Ultrathin Rx Progressive 1.67 No-Line Bifocal lenses for $269.
What's the best way to clean my lenses?
For everyday cleaning of smudges or prints, we give you a handy DITTO lens cloth with every pair of glasses ordered. For a more comprehensive cleaning job, just rinse your lenses with lukewarm water and mild soap, and pat dry with a paper towel. Be careful not to use hot water which can warp the plastic frames.

What is pupillary distance? how can I get it measured?
Pupillary distance (PD) is the distance between the centers of your pupils, measured in millimeters. We use this measurement to effectively center your prescription in your lens. If your PD is not written directly on your prescription, it may still be on file with your doctor. If not, we recommend having your PD measured professionally by your doctor, or at any optometrist. This measurement is often taken for free and only takes a moment. If for any reason you are charged a convenience fee, just send us a receipt, and we’ll deduct that amount from your order.
How do I submit my eyeglass prescription?
You have three options for submitting your prescription. 1) You may enter it directly on the website during checkout; 2) Simply send us a copy via email; or 3) Give us your doctor’s contact information, and we'll be happy to contact the office directly. Please note that if you live in one of the following states, we are required to verify your prescription by either obtaining a copy of it (via email) or by speaking directly to your doctor: AK, AL, AR, AZ, CA, CT, FL, GA, HI, KY, MA,NC, NJ, NV, NY, OH, RI, SC, TN, VA, VT, WA.
Do you accept contact lens prescriptions for glasses?
Sorry, Charlie - contact lens and eyeglass prescriptions aren't interchangeable. Though the prescriptions may appear similar, they differ in strength. For your safety, we can't use your contact lens prescription to make your prescription lenses.
Oops! I messed up the prescription. what should I do?
We review every order carefully. But, we won't know if you meant to type 5 instead of 6, for example, so it's important you enter your information carefully and accurately. If we do come across anything noteworthy or clearly awry, we contact you to clarify. The best way to ensure the accuracy of your prescription is to provide us with a copy of your prescription.
