Presbyopia
Presbyopia naturally develops as we age. As with the rest of our body, our
eyes age as well. Difficulty focusing up close is the signal that
presbyopia is developing. Fortunately, corrective lenses can help.
What is presbyopia?
Presbyopia results when the lens of the eye grows thicker and becomes less
flexible. The lens of the eye is integral for both distant and near
vision. With presbyopia, the muscles around the lens that allow it to
expand and contract, changing the curvature of the lens depending on near
or distant vision, still operate, but the lens itself is unable to change
it's curvature or shape adequately. This results in images focused behind
the retina instead of on the retina. The result is blurred close up
vision.
Are you at risk?
Everyone is at risk for developing presbyopia. Indeed, as the eyes age,
presbyopia naturally results. The majority of people begin to experience
signs of presbyopia around the age of 45, although it can develop at a
younger age. Signs that presbyopia is developing include an increased
inability to see up close, for example, when reading. Those who are
nearsighted and wear corrective lenses to see at a distance may be less
likely to notice presbyopia developing; however, over time they will
require vision aids for close work.
Minimizing the risks
No one can prevent the natural aging of the eyes and subsequent vision
loss. However, ensuring that you are keeping your eyes as healthy as
possible is the best way to slow the development of presbyopia. Tips about
how to maintain good vision health are outlined below.
1) Regular Eye Exams
All individuals should have regular
eye exams. How often eye exams are
required depends on certain factors. For those without eye problems, eye
exams should be carried out every two to four years. Those over the age of
65 or those younger with vision problems, should undergo an eye exam every
two years at least, or more often if advised to do so by an eye doctor.
2) Use Adequate Corrective Lenses
Ensuring that your corrective lenses are providing optimum benefit to your
vision is always important.
3) Manage Chronic Health Conditions Well
Some health conditions can negatively impact vision. These include high
blood pressure, diabetes, and several others. Understand whether your
health condition can impact your vision.
4) Wear Sunglasses
Protecting your eyes from the harmful affect of UV rays is important.
Always wear sunglasses when outdoors and ensure that the sunglasses you're
wearing block at least 99% of UVA and UVB rays. Some medications, along
with eye surgeries, can leave your eyes more vulnerable to the sun's
harmful rays.
5) Maintain a Good Diet
Vitamin A and Beta Carotene have long been recognized for their valuable
impact on maintaining healthy eyes.
6) Use Good Lighting
Adequate lighting is not only important when reading, but helps avoid eye
strain at all times.
Diagnosing Presbyopia
Presbyopia is easily diagnosed through regular eye examinations. Through
both visual tests and a thorough examination of the inside of the eyes,
the development of presbyopia can be easily recognized. Treatment options
for presbyopia include vision aids, such as corrective lenses, bifocals,
trifocals, and modified monovision lenses. As well, corrective surgery,
such as LASIK or PRK can be employed to treat the effects of presbyopia in
conjunction with other vision problems.
