Single Vision lenses have the same focal power over the whole lens. These are the most commonly prescribed lenses, providing visual correction either up close or at long distances. Most individuals who wear glasses before the age of 40 will usually be prescribed single vision lenses.
If you have difficulties focusing on objects in the far distance (shortsighted), single vision lenses will assist you to see clearly and carry out activities such as driving and playing sport with confidence.
If you have trouble focusing on objects up close (longsighted), with single vision lenses you can continue to undertake close tasks such as reading and sewing with ease. These lenses are commonly known as Readers.
Extended Readers are another option which provide the additional benefit of an intermediate viewing zone as well as a close viewing zone. If you work in an office environment or spend a bit of time on a computer, this option can deliver greater benefits and flexibility.
