What you'll need

A mobile device and computer or tablet display
Your computer or tablet will serve as a digital eye chart and you'll use your mobile device as a remote control to tell us what you see on the computer screen. No app download is needed.

10 feet of space
Stepping away from your device lets us measure your distance vision. You’ll need to stand about 10 feet from your screen.

Prior prescription
Your previous prescription is required. Our doctors use it to ensure your new prescription is clear and comfortable. We're happy to get a copy from your last doctor, but it can cause delays.

Note - This test is suitable for renewing all contact lens prescription types. However, Perfectlensworld does not sell multifocal, toric & astigmatism, or +PWR contact lenses. If you need this type of lens, we recommend you visit your eye care specialist.
