Can anyone wear Autofocals?

In theory, yes. Although we primarily target customers aged 30+, who are more prone to weaker eyesight.

What is the difference between Multifocals and Autofocals?

Unlike Multifocal lenses, which feature a single layer lens, each pair of Morrow Autofocals feature two ultra-precise, thin-cut optical lenses, with a delicate layer of our pioneered Active Liquid Crystal embedded between them.
When you click the button to adjust your prescription, a small surge of electrical current passes through to the lens, instructing the Active Liquid Crystal to refract light in a pre-prescribed way. This allows you to switch up your vision from near to far in just 0.6 seconds and experience a significantly sharper focus and a much wider view; that will shorten your focal zones as your vision deteriorates.

How long does the battery last?

Our super-slim battery is energised to deliver (up to) 48 hours near vision in between charge cycles, and only requires 1 hour to recharge from zero to 100%.

Why do Autofocals have Bluetooth?

So you can connect your eyewear to any smart device, to provide battery status notifications and Autofocal Eyewear software updates.

Why do Autofocals fold differently?

Our fold makes space for our super slim battery unit.

Are Autofocals waterproof?

Morrow Autofocals are not fully waterproof, they are IP54 standard splash proof.

Every one of our frames is engineered and 3D printed to order. So we can assure your Autofocals will have a millimetre-perfect fit.

What is 3D-printing?

3D-Printing is the process we use to create your Autofocal frames. It’s an innovative way of forging three-dimensional objects, that are constructed layer-by-layer.

Why are Autofocals 3D-printed?

3D-printing enables us to create your Autofocals with the utmost accuracy and precision.

Our advanced Autofocals require a level of accuracy no other eyewear prescription could offer – and you’ll see the difference.

What is Precision-Fit?

All our Autofocals are Precision-FitTM for ultimate comfort. This means we take all optical measurements during your Eye Exam and calculate accurate dimensions for every detail, including your PD, Seg Height and Temple Zone. Precision-FitTM ensures your Autofocal frames are engineered to your exact fit.
