How to Read an Eyeglass Prescription

SPH (Sphere)

Spherical error, or overall power of lens is the basic part of your prescription. A (+) means you have trouble seeing near, and a (-) means you have trouble seeing things faraway.

CYL (Cylinder) & Axis

A cylinder value indicates astigmatisms or perpetually blurry vision. Axis—measured between 1 and 180°— tell us the orientation of the astigmatism

ADD (Addition)

This number is sometimes written NV for near vision and is used for multifocal lenses and readers

PD (Pupillary Distance)

It's just what sounds like—the distance in millimeters (mm) between your pupils. An average PD measurement is 63 mm, but varies by person. If it's not on the prescription, you can measure it yourself by:
• printing the downloadable PD ruler.
• watching our tutorial video.

PRISM

We can process prism prescriptions to correct eye orientation

Vertical Prism is used to help correct vertical eye misalignments and is prescribed in opposite directions for both eyes

Horizontal Prism is used to help correct lateral eye misalignments and is always prescribed in the same direction for both eyes

Why Tortoise Shell?

Tortoiseshell glasses are all the rage, to a point where you'll see people sporting them all over the place. There are several good reasons why tortoiseshell is a pattern that transcends the decades:

• Plenty of Color Options: Tortoiseshell describes a pattern rather than a set color palette. Tortoise can mean anything from a mottled yellow to a honeyed brown or black patterned look. There are even vibrant options with pink or blue tinges! No matter your skin, hair color, or aesthetic, you're sure to find a tortoise color combination that fits you!
• Constantly Trendy: Tortoiseshell has made a huge comeback in recent years, mostly because of modern hipster and vintage style trends. If a retro feel is what you're looking for, Tortoise sunglasses are a great option for you!
• Vast Style Options: The best thing about tortoise is that it works with any frame shape. Whether you’re looking for retro shapes, modern forms, or something between the two, tortoiseshell is always a great color option to bring it all together.
