Slideshow: How Your Vision Changes as
You Age
1/9
Computers and Eye Strain
Staring at computer
monitors, smartphones, and video game screens may result in strained, dry, and
tired eyes. Luckily, using these devices does not seem to have permanent
effects. To prevent eye strain, adjust your computer monitor so that it's 2
feet in front of you. Use desk lighting to reduce glare. Take a break every
hour. Spend a few minutes looking at something much farther away than the
monitor.

Protect Your Eyes!
Healthy adults younger
than 40 usually have stable vision. To maintain your vision and overall eye
health, wear sunglasses that have UV protection. Wear protective gear when
playing sports or working with power tools, machinery, or chemicals -- both at
work and at home.

Oh, No! It's Time for "Readers"
The
need for reading glasses happens to almost everyone. By the time you reach your
mid-40s, it may be tough to read and perform other close-up tasks. This vision
change is called presbyopia, and it's normal. You can wear reading glasses,
bifocals, or multifocal contact lenses to correct
your vision. Sometimes laser surgery can help, too.

What Happens in Presbyopia
Before the age of 40,
the natural lens of the eye is very flexible. This helps the lens focus on
objects that are close up or far away. But as we get older, the lens tends to
lose its flexibility. Gradually this lowers the ability to see up-close objects, especially in low light. If you have
presbyopia, you might have to hold an object like a book or a menu farther away
to see it clearly.

Age-Related Diseases and Vision
Some diseases, like
diabetes and high blood pressure, can affect vision and eye health. Diabetes is
a leading cause of blindness in adults. People with diabetes may develop
retinopathy (shown, damage to blood vessels in the retina). High blood pressure
can damage the eye's blood vessels and nerves. It can cause permanent vision
loss. When you take care of your overall health by eating well and not smoking,
your eyes (and the rest of your body) benefit.

Cataracts and Glaucoma
Cataracts (shown) and
glaucoma can happen at any age, but they most often happen in people over 60. A
cataract is a clouding of the eye's lens. It can easily be removed and replaced
by a special lens during surgery. Glaucoma is a deterioration of the eye's
nerve over time. It is often accompanied by increased pressure in the eye.
Glaucoma is treated with eyedrops or surgery to decrease eye pressure.

Slowing Down Macular Degeneration
Age-related macular
degeneration (AMD) is more common in people over 60. It can cause a partial
loss of vision. "Wet" AMD happens when new, unwanted, leaky blood
vessels grow in the eye. It can be treated with medicine. "Dry" AMD
is a slower process and does not have a specific treatment. But certain
doses of vitamin and minerals may slow or stop it. Ask your doctor about that.
Vision rehabilitation may help you adjust to life with AMD.

Nutrition and Vision
A healthy diet can help
maintain your eye health. And some foods may be especially good for eyes, too.
Lutein, omega-3 fatty acids, and vitamins C and E may promote eye health. So
eat citrus fruits like oranges and tangerines, green, leafy vegetables, nuts,
and fatty fish. Eating fish and green, leafy vegetables may prevent age-related
macular degeneration, too.
