What Causes Presbyopia?
The lens is a small, nearly spherical part that sits inside the eye and helps to focus the light coming in. When you are younger, the lens has the ability to change shape easily. Tiny muscles contract and relax to control changes in the shape of the young lens, and this flexibility allows your eyes to focus over a broad range of distances. As we enter middle age, just as we also begin to notice the subtle aches and pains of aging in our bodies, the eye’s natural lens becomes thicker and begins to lose its flexibility, resulting in vision problems.
Presbyopia or the ‘aging eye‘ is a natural condition as we age where near vision task become more difficult. It starts about age 40, progresses in severity to age 65 and then remains stationary. The natural lens that sits behind the colored part of the eye called the iris loses it’s flexibility, becomes rigid, and no longer allows for objects within arms length to be focus. So, reading, viewing a smart phone or computer screen becomes limited if not impossible. Patients frequently complain of eye strain, headache, blurring, and fatigue quickly.
