Correcting Presbyopia with Lenses
For individuals that are dealing with presbyopia, the easiest way to help improve vision is to use reading glasses. Reading glasses can help to magnify vision for projects that are at close range, like reading. Reading glasses, or “Readers” that are available for purchase at drug stores would work to help correct the presbyopia. For higher quality glasses, an ophthalmologist or optometrist can prescribe you reading glasses to improve your close vision.
For those that already wear contacts for myopia or hyperopia, it is important to talk to your eye doctor to get the right reading glasses that work with your current prescription. The reading glasses will need to work with your current prescription to adjust for close up vision.
Bifocals, also known as progressive lenses are a type of glasses that can be worn to address presbyopia and myopia. The bottom portion of the bifocal lenses magnify to improve close vision, while the upper portion of the lens has a different point of focus to adjust for distance vision.
One other option for correcting presbyopia is called monovision. This technique is when contact lenses are used, but one contact lens is used to adjust for distance and the other contact lens adjusts for close vision. The brain will adapt to relying on one eye for distance and one eye for close vision.
Correcting Presbyopia with Surgery
One procedure called Conductive Keratoplasty (CK) is a procedure where the cornea is reshaped, using radio waves. The radio waves will increase the curvature of the cornea. The correction is temporary and will reduce over time.
Another procedure that can resolve presbyopia symptoms is a form of LASIK. In this LASIK procedure, similar to how monovision contact lenses would work, one eye is adjusted for distance vision, and the other eye is adjusted for close vision. The brain will adjust to relying on one eye for close vision and another eye for distance.
Lastly, refractive lens exchange is a procedure where the eye’s rigid and inflexible lens is replaced with a synthetic lens. The new lenses will correct the presbyopia, as well as other vision problems.
