Varifocal lenses

The upper part of the lens allows clear distance vision and for near vision, the bottom of the lens is used. For clear vision at arms length, the middle of the lens is used.

Using varifocal lenses eliminates the hassle of having to change your contact lenses or glasses for different purposes and allows you to carry on with your day to day activities.

They are especially suited to those who lead an active lifestyle as they are very convenient. For example in the course of one day, you might need to drive, read, go to the supermarket and do work on the computer. Instead of having to change from driving glasses, to reading glasses, and then to everyday long distance glasses, you wouldn't have to think about your vision at all.

Many jobs involve making quick and frequent changes to focussing on close up objects, to focussing on objects at a distance For example, a teacher needs to see near distances to read text, and write on the board, but must also be able to see to the back of the classroom. Using varifocals would ensure the teacher had clear vision at all times.

It is usually necessary to give yourself time to become used to varifocals. To focus on a certain object, you should move your head slightly until the object becomes clear to you. When driving, it is important to move your head to focus, not just your eyes. It can also be hard at first to perceive the space around you.

This may sound like a lot to become accustomed to, but it only takes a few days to become comfortable with and enjoy the full advantages of your varifocal lenses.
