Presbyopia is a condition in which the near vision becomes blurred and there is difficulty focusing while reading, using a computer, sewing or doing other things that require vision that is within an arm's length. It occurs as people age, when the natural lenses of the eyes become less flexible and begin to harden. This condition is usually age-related and often occurs after a person is 35 years of age or older. Depending on the severity of this condition, it can often be corrected. These are some of the ways that presbyopia is treated.
Eyeglasses can often help improve the vision of someone who has presbyopia. Bifocals are often prescribed for someone with this condition because they are designed with an upper area of the lens to improve distant vision and a lower are that is designed for improving up close vision. There is normally a thin line in between the two sections that is visible so the wearer knows where to look through for each type of vision.
Progressive addition lenses are also used to treat presbyopia. These are similar to bifocals, but there is a more gradual transition between the distance vision and near vision areas of the lenses. These lenses do not have a visible line like bifocals. If the person does not have severe presbyopia, it is also possible to improve the vision with only reading glasses that magnify what the person needs to see up close.
Multifocal contact lenses can also improve the vision of those who have presbyopia. These lenses are usually made of a soft lens material or gas permeable lens material. Some patients also opt for monovision contact lenses to correct this condition. This means that one eye wears a contact designed for distant vision and the other eye wears a contact designed for up close vision.
Eye surgery is also an option for correcting presbyopia. This surgery is done by using radio waves to create more curvature in the cornea so that the vision can be more easily corrected with prescription lenses. This type of procedure is often performed on only one eye so that he patient has up close vision in one eye and distance vision in the other. However, sometimes these results are only temporary.
Those who are older and have been diagnosed with presbyopia may need to have more frequent visits with their eye doctor. As a person ages, the lenses of the eyes tend to change and a stronger prescription may be necessary to correct the vision properly. To learn more, contact an eye clinic likeAll About Eyes.
