The last step: manufacturing of the glasses

You’ve sorted out the most important aspects of your glasses: corrective values, frame and suitable lenses including figures to enable accurate centring. Now the optician will see to the manufacturing and assembly of the glasses. This requires fine skill, as every pair of glasses is tailored to the person who’ll be wearing them.

The optician's process, step by step:

First comes quality control: What condition are the lenses in? Are they damaged, scratched, are there bubbles or inclusions? The optical values will be checked once again, just to be sure. Generally speaking, the lenses are manufactured individually and emerge in an uncut raw form.

Next is the cutting process, which means the lenses are adapted to the glasses form and the figures for centring, so that they fit perfectly into the frame. The opticians have to work with great precision here and make use of the latest technology, as every millimetre counts.

The method of lens insertion depends on the material of the frame and is always carried out by hand. Lenses are screwed into metal frames, while plastic frames are made flexible with heat so that the lenses can be inserted.

Then your glasses are ready to be sent to you at home.

Tip: You should allow for a little time to get used to the new glasses. Particularly when changing to varifocals the eyes require an adjustment period.
