Presbyopia
Presbyopia – the inability to see close objects.
This form of eyesight deterioration – specifically near vision - comes naturally with age and is caused by the loss of flexibility in the eye’s lens. As we age, elasticity in the lens is reduced. Presbyopia, the lack of flexibility of the crystalline lens of your eye, makes it difficult to focus on objects that are near.
You may have presbyopia if you show one or more of the following signs: tendency to hold reading material at arm’s length, blurred vision when holding reading material at a normal length, or eye fatigue and headaches when reading closely. To compensate for the signs and symptoms of presbyopia, Nikon and other companies like Essilor, Rodenstock, Zeiss and Hoya are some of the few Optical manufacturers that recommends either a near intermediate lense or progressives.
