Presbyopia is an age-related condition that causes close objects to appear blurry. At a young age, the natural lens is flexible and able to change its shape to focus on both close and distant objects. This process is called accommodation. As people age, accommodation no longer functions to its full degree. The natural lens gradually becomes harder and less flexible and loses its ability to change shape and focus the light directly onto the retina. This causes the focal point to lie behind the retina, resulting in a blurry image.
The onset of this condition usually happens from age 40, but varies from person to person. The deterioration of your vision might seem sudden, but the inflexibility of the natural lens, the cause of presbyopia, progresses over a number of years.
When presbyopia develops and to what degree depends on your individual anatomical conditions and your previously existing prescription.
Presbyopia can be diagnosed in a basic eye exam by an ophthalmologist or optometrist. You can also recognize presbyopia yourself from some common signs and symptoms, such as:
Other symptoms may include headaches, eyestrain and eye fatigue. It is important to visit an ophthalmologist or optometrist for regular eye exams.
Well over half the world’s population relies on glasses or contact lenses to see well. For many people, this starts becoming an issue around the age of 40, when the deterioration of the natural lens leads to needing reading glasses.
For many of these people, this may be the best option for them, and today, with advancements in medical technology there are a variety of options available for a wide range of vision needs. Bifocals and surgeries such as conventional monovision or intraocular lens exchange, provide an alternative solution for presbyopia, although they may compromise your ability to differentiate between distances. The use of trifocals and Laser Blended Vision however, enables you to switch easily between all distances.
Laser eye surgery can therefore provide a possible alternate solution to glasses and contact lenses. Consult with your eye doctor to determine the best option for your vision and daily life.
