A single vision prescription is a lens that has a single focus for either distance or reading vision.
A progressive prescription is a multifocal lens that has more than one point of focus, allowing someone to see clearly at distance, mid-range and reading, all in one pair of glasses.
Our standard lens is a lightweight polycarbonate lens with anti-reflective coating (AR), which diminishes glare and provides 100% UV-A and UV-B protection.
A transitional lens is a light responsive lens that changes color from clear (indoors) to a dark lens (outdoors). It's an eyeglass + sunglass all in one.
Blue AR Coating
Also known as blue filter lenses, blue AR coating is a lens treatment that blocks blue wavelength light. Invisible blue light emits from your tech device screens causing eye strain + irregular sleep patterns. This coating protects you from that! They are not actually blue...

If you’re not an existing Zak. patient or your previous Zak. order prescription is no longer valid, upload or email your valid glasses prescription, which should include your Pupillary Distance (PD). PD is the distance in millimeters between your pupils. This allows us to center your prescription, which is essential for the most accurate sight and comfort.
High index lenses are a thinner, lighter lens material. We generally recommend this type of lens material for prescriptions over 5.00 D in power as these prescriptions will appear bulky and thick in a standard lens. Not sure if you need this? Email Hello@zakeyes.com + we'll talk you through it.
