If you spot these, visit your Ophthalmologist
You've had your glasses for years, and you still think you
can see clearly out of them after all this time. Although you think you may be
able to see just fine, there could be changes in your vision that you haven't
even noticed. But how can you tell when you need a new prescription for your
glasses? Here are five signs you may need a new drug:
Squinting:
People who are constantly squinting usually have a problem
seeing clearly. Squinting is a natural way to improve focus and clarity, and
you may not even realize you're doing it until your eyes and head begin to
hurt. However, squinting causes more damage than good in the long run. When
squinting, you excessively strain your eye, making your vision problems even
worse. If you notice yourself squinting more when reading a book or on the
computer, you might need an updated prescription.
Blurry vision:
If you have a sudden or occasional blur of vision,
accompanied by a loss of focus, you are experiencing a blurred image. This can
occur in one or both eyes and can be due to a severe change in your vision. A
new prescription and further testing will be needed to clarify more significant
issues, such as cataracts.
Persistent Headaches:
People usually fail to associate their recurring headaches
with a change in their vision – one of the earliest signs of change. People
don't even notice the slightest difference in their sight, but they also don't
realize that their brain can recognize this change. Once alerted, the brain
will work hard to try and correct the problem, but in doing so uses too much
energy and eventually wears itself out.
