Presbyopia is a natural condition experienced by people generally after the age of 40 years old. Symptoms of presbyopia include visual blur and discomfort for near work. The main cause of this phenomenon is the ageing of the crystalline lens resulting in decreased accommodation (that is the capability of the lens to change its dioptric power when focusing at near).
There are different ways to manage presbyopia, including bifocal lenses that is and old type of lens, varifocals that give a gradual change in the prescription, reading glasses or even contact lenses that give freedom from glasses with very positive outcomes.
Based on the needs and lifestyles of each person the optometrist can recommend the best available option to correct presbyopia.
