A good vision is one key to productivity. Unfortunately, the condition can worsen eyesight as you age. Healthy habits and keep your intake of essential nutrients for eye conditions is maintained.
The outer portion of the eye is the cornea, allowing light spherical bulge can enter the eye. The light then passes through the pupil, transparent space located in the middle of the iris. Behind the lens of the eye pupil are connected to the zonules, which serves to tighten the muscle fibers and loosen the focus.
Light entering through the lens and the retina, the tissue at the back of the eye. Retina then sends the signal through the optic nerve to the brain to translate what is seen by the eye.
Ages 0 - to 30-year
At birth, the lens inside the eye color are generally clear and flexible. Zonules are connected to the eyepiece is still strong.
As you age, the lens becomes less flexible, and zonules are ineffective and require corrective lenses. If the eyeball is too long, there will be nearsighted.
If the eyeball is rather short, then there was farsighted. Each time feeling the change vision, you should immediately see an eye doctor.
To avoid damage to vision, eye exercises eye as directed. Get used to the habit of reading and watching TV sound.
Lutein is found in green leafy vegetables like spinach and kale is one of the antioxidant protective eyewear. Sweet corn, peas and broccoli also contain lots of lutein.
Vitamin A is essential for healthy vision and is usually found in orange and yellow vegetables like carrots and pumpkin. Fruits and vegetables also provide essential vitamins C, other antioxidants are good for the eyes.

40-year age
"This age is when people start to lose the ability to focus vision at close range. Condition is called presbyopia," said Dr. Andrew Iwach, spokesperson for the American Academy of Ophthalmology and executive director of the Glaucoma Center of San Francisco as reported by FoxNews on Tuesday (20/3 / 2012).
The cause is a lens that retracts, harder and zonules are weakened. For correcting vision, use reading glasses. How fast is the occurrence of presbyopia is different for each person.
"If you always have perfect vision, reading glasses may be used only at the early age of 40 years. People who have nearsightedness is more resistant to this disorder and often do not see any change in vision due to age presbiopi reached the end of 40 years," said Jill Koury, assistant professor of ophthalmology at the University DukeEye Center, in Durham, North Carolina.
If you experience nearsightedness, reading glasses may be made at the age of 30 years. Age is also a good time to test a comprehensive vision. The doctor will test the pressure inside the eye and optic nerve check to see if the nerves are still intact.
Age of 50 years and over
At this age, the more the lens hardens and may need to wear corrective lenses is strong. This age are also at risk of experiencing eye diseases as follows:
A. Cataracts.
Occurs when the eye's lens becomes cloudy. More than 20 million Americans have cataract. The main cause of this disease is aging. Smoking and sun exposure also trigger cataracts. If not treated, can lead to blindness.
Researchers in the Blue Mountains Eye found that vitamin B, folic acid and vitamin B12 reduces the risk of cataract formation. Research also shows that consuming omega-3 fatty acids per day could reduce the risk of cataracts.
2. Glaucoma.
The disease is associated with a form of pressure inside the eye which causes damage to the optic nerve. Glaucoma causes loss of vision slowly and eventually lead to blindness. This disease is one of the most common reasons leading cause of blindness worldwide.
3. Damage to the macula.
The macula is a part of the retina. The macula may be damaged due to heredity or environmental factors that lead to impaired vision.
Early signs are blurred vision. Macular degeneration is the leading cause of vision loss in people over the age of 65 years. Exposure to ultraviolet (UV) can accelerate damage to the macula same as cigarettes.
The study found that a combination of vitamin C, beta carotene (vitamin A-forming), vitamin E and zinc can reduce the risk of macular degeneration.
