Eyecode – A unique breakthrough in lens personalisation

Eyecode is a unique breakthrough in spectacle lens personalisation and is at the forefront of innovation.

For the first time, we are able to measure the unique code of each human eye. Currently, all lenses that are manufactured assume every person has the same Eye Rotation Centre (ERC), when in fact it can vary by as much as 30%.

The dynamic 3D measurements can only be measured only by specialised computer equipment, which  is now available at Hammond Opticians. Eyecode by Essilor is a technology which pinpoints the exact Eye Rotation Centre, which is unique to every person. By doing so the technology delivers a truly tailored eye diagnosis, that is quick, easy to determine and highly accurate. This measurement is called Eyecode.

Eyecode can be combined with the frame and behaviour parameters to deliver lenses that are truly tailored to each wearer.

The benefits to you

  • Lenses that are five times more precise, giving a total lens-to-eye synergy
