Every pair of reading glasses or "eye appliances" has an HEV coating that blocks blue light emitted by electronics. This will help with eye strain, blurred vision, sleep interruption and headaches. If you do not need readers yet, they do have some +0.00 magnification lenses in some selected styles.
Caddis also offers sun readers that look like stylish sunglasses; however, behind those dark UV-blocking lenses are bifocal reading segments that allow you to look through two areas of the lens. The upper portion of the lens has no magnification for focus on distant objects. The bifocal segment is for reading at close distance in bright conditions.
+1.00: If you're new to corrective eyewear, 40 or older, or believe that you don’t need glasses and you’re at least 45 years old, start with a 1.00. In the last several years we wish we had a buck for every time one of our friends said, “Cool company...but I don’t need reading glasses..” then we handed them a pair of 1.00 and without fail, "Holi shit!... this is awesome". This is the gateway drug game-changer magnification level most start with.
+1.50: As you begin to recognize the need, and eventual addiction, to seeing things clear again, you’ll want to upgrade and have a pair of +1.50 around. There are times of the day where the extra boost is welcomed.
+2.00: More than likely, you’re already a buyer and user of corrective eyewear, so from here on out, you have some idea of what you need. More times than not, your first rodeo is not with a set of +2.00. You’ve probably flirted with the tower of shame at CVS, Walgreens, Krogers, etc....the one that sits between the Dr. Scholls display and the Sonicare refill kits. You probably didn’t feel all that awesome...our goal is to change all that.
+2.50: varsity league user. We don’t need to tell you anything that you don’t already know. We also want to thank you for being a model citizen for those who will come after you. You're a pioneer.
+3.0 to +4.0: We got one word for our people in this group... Magoo. You know who you are, and you know what we mean. Who loves you.... we do.
