Inside of the eye is a lens called the crystalline lens, this lens is clear and to some extend flexible. This lens is responsible for the 

focusing mechanism of the eye at near. As it ages it becomes dull in color and looses its flexibility which leads to accomodate (focus) lag. The older you are the more power you will need for reading at near.  After age 50 it tends to become stable as for the need of reading power. In your 60's your lens starts to become yellow and eventually will create glare, requiring the cataract surgery. Come to us for a free cataract screening. We will give you an unbiased opinion. 

If you do require cataract surgery be aware that you will require a man made intra ocular lens to replace your crystalline lens. Cataract surgeons will give you options depending on your refractive error and needs. After surgery most likely your dependence on glasses or contact lenses will be less. Almost all patients may function without glasses. On the other hand, most patients will benefit from small corrections to enhance viewing and protection of coatings such as Crizal and UV protection.
