Presbyopia is the natural evolution of the eyesight and concerns everyone as from the age of forty. The crystalline lens loses its flexibility, bulging insufficiently, and adapts with difficulty. This results in an increasing difficulty to see from near.
These are symptoms of presbyopia.
There exist several types of corrective lenses. In order to advise you on lenses that are best adapted to your expectations and needs, specialists may question you on your professional, as well as leisure, activities.
Even if all lenses prescribed for presbyopia enable you to see from near, they do not have the same characteristics.
Simple vision lenses for reading are very well adapted to reading newspapers, sewing, writing, without ever looking beyond. But as soon as you raise your eyes to see what is in the distance, images appear blurred. You are then forced to continuously remove and put back your glasses on or to glance above them.
Bifocal lenses make it possible to see from near and far but they are characterised by a glaring boundary line. This line is an obstacle to your eyes, which brutally have to adapt from distant vision to near vision.
Progressive lenses allow you to see clearly at any distance and restore the entire field of vision. Their highly aqueous materials ensure comfort and respect for the eye. Thus, all types of sports activities can be practised.
