Meaning "elderly eye" in Greek, presbyopia is an eye condition that mostly affects people from the age of forty years and upwards. The main symptoms are blurred vision when carrying out an activity such as reading a book or using a computer. Unfortunately, presbyopia cannot be prevented, but the symptoms can be controlled to an extent.
One of the first signs of the condition is when people have to hold reading material such as books and newspapers at arm's length to be able to focus correctly on the words. If they need to concentrate their vision in this manner then they may suffer headaches from eye strain.
Presbyopia is not due to the same factors as astigmatism, farsightedness, or nearsightedness. These eye problems are caused by the shape of the eyeball as well as genetic problems, but presbyopia is thought to be caused by a thickening, and lack of flexibility, in the lens of the eye due to changes in the proteins that are present. Also it is believed that the muscle fibers that surround the lens loose a degree of their elasticity.
To treat presbyopia and correct the vision it is possible to use eyewear or undergo surgery. If you choose eyewear then you can be given bifocal lenses or progressive addition lenses.
Bifocal lenses work by having two different strengths within a single lens - the main part has a prescription to improve distant vision and the lower part has a strength to improve up close vision. If you would prefer a more natural progression in the lens from one strength to the other then progressive addition lenses would be better for you.
If your distant vision is fine, then you can choose to wear reading glasses whenever you require up close vision. These can also be used by people who have poor distant vision and wear contact lenses.
As we all age it is likely that the deterioration in the eye's lens will get worse over time. For this reason whatever eye wear is prescribed will have to be increased in strength every so often.
It is now also possible to have surgery to counter balance the problems caused by presbyopia. One such option is Conductive Keratoplasty treatment; this involves an alteration of the curvature of the cornea through the application of radio waves. Another method is LASIK surgery, this changes the shape of the cornea through laser pulses.
