Single vision lenses have one single prescription across their entire surface and are suitable in all scenarios, whether you need your glasses for driving, working or reading.
Eyes change throughout our lives, gradually losing the ability to focus on close objects. During our mid-forties, the lenses in our eyes become stiffer, and the muscles that control them change - which eventually causes blurred vision. This is called Presbyopia, and it happens to all of us. You'll probably find yourself holding books, newspapers or product labels further away, or needing more light in order to read clearly.
A bifocal lens provides distance and near vision in one lens. The near vision correction of the lens is contained in a segment, often visible on the front of the lens. This segment provides the extra power necessary for you to read clearly.
At Vision Express we will recommend the best option for you. For reading, this could be single vision lenses dedicated to your needs - or you may be looking for a quick solution to keep handy by using Ready Readers. We have a full range in our accessories section in store.
