Lens centering and precision measurements in Blida

Why centering is decisive

Even an excellent lens is only comfortable if it is centered exactly in front of your eye. A few millimetres off is enough to cause eye strain, headaches or distorted vision.

Complete measurements, never approximate

From your prescription, we take pupillary distance, fitting height, pantoscopic angle and lens-to-eye distance — taking your frame and posture into account.

Frequently asked questions

Is centering really that important?

Yes, it's the step that determines your real comfort, far more than people think, especially for progressive lenses.

My glasses strain my eyes — is it the centering?

Very often. Poor centering or a badly measured height strains the eyes. We re-take the measurements to check.

Do you center lenses on my own frame?

Yes, we measure and center the lenses based on the frame you wear or choose.
