DELAY PRESBYOPIA. CAN PRESBYOPIA BE PREVENTED?

 

Presbyopia can not be prevented or delayed because it is not a disease, but a natural process. Presbyopia, also known as a tired eye, is a visual defect associated with the age by which the lens loses elasticity so that the eye sees reduced its ability to adapt and therefore to see up close. Presbyopia, being related to an age-related degenerative process, can not be prevented.

THIN PROGRESSIVES, WHAT THICKNESS HAS A PROGRESSIVE LENS?

There are several parameters that must be taken into account when defining and evaluating the thickness of a progressive lens such as the graduation of the user, matter with which the lens is manufactured as well as the index of refraction of the same. Also the shape of the chosen frame and the nasopupilar distances ( the nasopupilar distance is the distance between the axis of symmetry of the face and the center of the pupil) of the user.

ARE ALL PROGRESSIVE LENSES THE SAME?

No. There are more advanced and more basic correction products. Progressive lenses of old traditional generation solve your visual needs in a very generic and inaccurate way.

80% of the information we receive is through the eyes, which is why it is worth using a more advanced and complete product.
