1. An apparatus for projecting a progressive addition lens in front of an eye of a user of the apparatus, the apparatus comprising:
a first support for supporting the progressive addition lens in a PAL plane;
a projection system configured for:
projecting without inversion the PAL plane onto a conjugated PAL plane, and
generating a non-inverted projection of an object through the PAL plane onto a retina of the eye;
wherein in the position of use of the apparatus:
the first support is configured to support the PAL lens such that the PAL plane is placed in a distal portion of the apparatus;
the projection system is located between the PAL plane and the eye;
a proximal portion of the apparatus is to be placed in front of the eye, and
the eye is placed at a first distance from the conjugated PAL plane.
