After your eye examinations, you can get a copy of your eye prescription from the optician or optometrist. Please offer us the most recent prescription data.

This tutorial blog has exclusively explained all those specifications and numbers on your prescription. If you have any other things unclear, feel free to contact us.

Single vision lenses only offer a single optical prescription and distribute focus evenly over the entire surface area of the lens, for farsightedness, nearsightedness, or astigmatism, or only for reading glasses. Most glasses wearers will choose single vision lenses. If there is an “ADD” number on your prescription besides Sphere or Cylinder, you might also need reading vision correction. You might need bifocal lenses then.

We recommend frames at least 28mm for bifocal lenses.

Only when you found a prism correction on your prescription, you will need it. Prism correction is for people who have double vision or vision displacement. With prism correction aligning separated images, wearers will no longer experience double vision. Yes, we offer prism correction, please click “show more options” to enter prism correction on the page “customize your prescription”

Cylinder indicates lens power need if you have astigmatism. If your doctor did not write Cylinder in your prescription, it means you have no or little astigmatism to correct. If there is Cylinder power, then there must be Axis value included, usually follows CYL. It indicates the angle between two meridians of an astigmatic eye.  

Pupillary distance measures the distance between the centers of your pupils. Normally the optician will measure your PD on your prescription. For the average adults, PD is between 54mm – 74mm. For kids, it will be 43 – 58mm. Pupillary distance should be offered for most accuracy of the prescription lens made. You can also measure PD yourself. We have a guide for that, Please check THE GUIDE

Sorry, the answer is no. As the manufacturing process of basic color tint and photochromic lenses are different, and they can not be applied to the same lens.

Contact lens prescription is only for contact lens, prescription for contact lens and eyeglasses can not be used interchangeably. The main difference lies in the way a prescription is measured. For contact lens, the prescription measures for lenses that sit directly on the surface of the eye. For prescription glasses, it measures for lenses that are positioned approximately 12 millimeters from the eyes.

It’s based on your needs. If you use it for activities in daily life, choose Distance. If you only use it for reading, choose Reading. If you wanna use it for both distance and close vision, choose bifocal.

We note frame sizes on the product specification part. And Most frames are built with spring hinges which offer a bit more leeway for a better fit and more comfort. If you did not find the frames that are suitable, please contact us and we will recommend a list of products for you.

90% prescription lenses from Joopin are made from Polycarbonate lenses, a type of optical plastic polymer that enables excellent clarity and durability for wearers to use. This material is also available with frames. For stronger prescriptions, we also support high-index plastic lenses that are thinner and lighter than standard lenses.

For frames that are available for prescription, you can see the “add prescription” button on the product page. If not, then the frames do not support prescription.
