Center of ocular rotation

It is possible to design customized lenses with minimum aberrations and maximum field of view by accurately measuring the ocular center of rotation and visual axis.

What is the center of ocular rotation?

The center of ocular rotation is the exact point at which the visual axes cross at two different fixation positions depending on the rotation of the eyeball.

It is a variable functional and dynamic location between individuals and even between eyes of the same individual.

Measuring the ocular center of rotation allows the design of lenses with the exact powers for different gaze positions outside the paraxial zone.

But... Why is it so important to measure the position of the ocular center of rotation?

1. Lenses with less aberrations and larger field of view.

Accurate calculation of the ocular center of rotation allows the design of ophthalmic lenses, considerably reducing aberrations (geometric and power) and increasing the field of vision. Especially when combined with the measurement of the distance and near visual axis.

2. Clear vision in all viewing positions

The exact position of the ocular center of rotation is a key factor in designing customized lenses that allow maximum quality of vision wherever you look. The ErgoFocus Plus System from Lentitech Technologies allows the center of ocular rotation to be measured quickly and accurately in various gaze positions.

3. Ideal for both single vision and progressive lenses.

All ophthalmic lens wearers can benefit from the advantages of designing a lens with accurate ocular center of rotation data. The higher the power, the greater the benefit.

4. freeform technology enables point-to-point lens designs

Measuring the ocular center of rotation allows the design of lenses with the exact powers for different gaze positions outside the paraxial zone.

Lentitech has developed the ErgoFocus Plus System to accurately and easily measure the center of ocular rotation.
