The easiest and most trusted way to obtain your prescription is to see your local optometrist. Please be sure to ask your doctor to include your pupillary distance (PD) on your prescription! If you have any problems while entering the prescription, Please contact us.

Before you order, you’ll need to enter a valid eyeglasses prescription (make sure it’s not for contacts!) and your pupillary distance (PD). to proceed. The PD is the distance in millimeters between your pupils, and helps us center your prescription correctly in your frames. Make sure this information is provided in your submitting prescription.

We strongly recommend that you get an eye exam every two years, or more frequently if you notice that your vision has changed.

Unfortunately, contact lens and eyeglass prescriptions are different. The simple reason is because contact lenses sit directly on your eyes, while eyeglasses are held in front of your eyes. Though the prescriptions may appear similar, they will differ in strength and are not interchangeable. We cannot — and, for your safety, would not — use your contact lens prescription to make your glasses. And we would advise you to contact your eye doctor to get your eyeglasses prescription.

Different prescription have different customization time. The more complicated the prescription , The more functions of the lens , the more customization time will be required. It usually takes 3-9 working days to customize prescription glasses.

For bifocals, frames must be at least 30mm. Progressive lenses, frames must be at least 33mm.

Thickness of the lenses depends on a few factors.
1. Prescription strength. The stronger the prescription, the thicker the lens, all else being equal.
2. Frame selection/fit. All else being equal, the larger the size of the lens, the thicker it gets (thickness proportional to size).
3. The higher the index of refraction, the less of a material is necessary to bend, or focus, the light in the same way for the same prescription. So, higher index material lenses will also reduce thickness and “”Coke bottle”” effect.

This is a fairly common when your eyes get used to the new glasses. It often occurs if the new glasses are of a higher prescription or you chose a larger frame than what you are used to. High index lens can also cause this issue. If you’ve been wearing the old glasses for a long time, your brain gets used to this and can find it hard to adjust if the prescription is changed. So you need to more time to get used to the new glasses. If you can’t get used to it for a long time, please check if the prescription is too high to get used to, and consult with your optometrist about the problem. Then you can contact with us for replacing the glasses to solve this issue.

The photochromic lenses become dark due to the penetration of the sun’s ultraviolet radiation. Photochromic lenses typically will not darken inside a vehicle because the windshield glass blocks most UV rays.

Because all LCD screens use polarized light and you are seeing the interaction of the polarizing filter in your glasses with that light which is causing moire patterns.
LCD displays use transistors to “twist” liquid-crystal material, causing it to block the backlighting that allows you to see the screen on a pixel-by-pixel basis. That liquid-crystal material, however, can only block light that is oriented in a “single direction”. For this reason, all LCD displays use polarizing filters to attenuate the backlight accordingly.
When you look at polarized light through your glasses, you can easily see the interaction of the display’s light source with your glasses (tilt and rotate the phone and you can likely watch this effect change).
