Using contact lenses to treat presbyopia

There are many medical issues that come along continuously as you age. One of them is poor vision. As you age, your eye lens becomes harder. This makes it hard for the lens to adjust to concentrate on different objects that are at different distances from the eye.

Poor vision thanks to age factor is known as presbyopia. Though presbyopia is inevitable, it can be corrected for sure. There are essentially 3 kinds of coloured contacts available : visibility tints ( not used for changing the color of your eye, only to help in seeing the lens ), enhancement tints or single-layer lenses, and opaque color tints or dual-layer lenses. Most providers of coloured contacts can offer the lenses in a prescription or non-prescription variety.
Let us have a look at some of the common options as regards contact lenses that you can put to use for treating presbyopia.
