Presbyopia is a normal decline in close-range focusing ability of our eyes with time. Presbyopia seems to present close-range issues suddenly but actually it does not. Our eyes have maximum focusing ability in our teens, about 50% at age 40, and we gradually decline to a fixed non-variable focus around the age of 70. The average person requires a different prescription for distance vs. reading tasks around the age of 42.
Most people falsely think that muscles inside the eye weaken over time causing this gradual loss of close-range focus. To the contrary, presbyopia is a loss of elasticity of the focusing lens inside the eye. In addition, many falsely believe that if eyeglasses are worn often it will weaken the eyes’ further. It is important to understand that wearing appropriate eyeglasses or multi-focus contact lenses full-time or part-time will not weaken or change your future visual status in any way. All humans experience this unavoidable and fully correctable visual condition.
