The Properties of The Start-Aging Eye
Thursday, October 13th, 2011Decrease in vision with age is often lamented by many people. Even if they still young, many people have begun to decreased vision.
Most people began to find that, when experiencing it reaches the age of 40 years, vision loss, even more visibility. Decreased visual function is an inevitable consequence of aging with chronic illness or degenerative disease associated.
Some changes or decreases in relation to a sense of vision with age, as quoted from BBCHealth, Tuesday (01/11/2011), including:
1. Usually it is harder to read, especially if the lighting is less.
This is called presbyopia and occurs as a result of changes in eye tissue. Especially in the lens is larger and less flexible. Thus drives the ability to focus the lens. This can be corrected by glasses with the correct size.
2. Dazzled
Glare can also be a problem when a change in the lens of his eye. So that these changes lead to the light in the eye is distributed so that the focus is not good.
3. Difficulty to distinguish colors
Some people also decreased color vision. So it is difficult to distinguish the different colors.
4. The eyes are more dry
Significant changes in the eye are associated with age, the eyes more dry. This is caused by tears produced is less and changing the viscosity, so the tears are less efficient in forming a protective layer, which lubricates the eyes.
May start at the same time a variety of eye diseases and other conditions occur, so that worsen the decline in visual function. Some eye diseases and other conditions, including:
1. Glaucoma
Liquid remains in and out of the eye. But the treatment of glaucoma, the fluid flow from the brakes. Thus, the increased pressure within the eyeball permits. It can damage the optic nerve and nerve fibers in the retina and can eventually lead to blindness.
2. Cataract
Cataract is a clouding of the lens that prevents light reaching the back of the eye, making it difficult to see clearly. Cataracts usually develops in older people, but prompt treatment can restore vision.
Cataract is growing as women age. So it is with age-related horror star. Smoking and exposure to UV radiation is a risk factor for Qatar’s file.
Other causes of cataract are diseases such as diabetes, certain medications, as well as inflammation and damage to the eye is too long. The symptoms often occur with cataract, such as blurred vision, and blurred vision.
3. Age-related macular degeneration (AMD)
AMD is a disease of the macula, the area in the center of the retina. The macula contains a high density of light receptors, particularly the cone receptors. Cone receptor is a receptor that can recognize colors. So that the macula is very important for fine detail on an object directly in front of him.
Macular plays an important role in reading, writing, driving, and other detailed tasks. It is also possible to see faces and colors to recognize. AMD can lead to loss of central vision. There are two types of AMD, including:
4. Diabetes
Diabetes is one of the causes of cataracts. Many older people with a history of diabetes, the decline in vision to get worse.
5. High blood pressure (hypertension)
High blood pressure can work your heart harder than normal. Have under consideration of the heart and arteries at greater risk of damage.
High blood pressure increases the risk of heart attack, stroke, kidney failure, eye damage, heart failure and atherosclerosis.
To the deterioration of vision associated with aging can be extended:
1. Perform eye tests at least every two years and always make sure glasses are in good condition.
2. Consult a doctor for problems such as hypertension or diabetes and taking medication as recommended to prevent eye damage.
3. With the help of reading glasses or bifocal / Vario.
4. If you want to read, to ensure that the lighting is very good.
5. Use eye drops or artificial tears to the eyes lubricated and comfortable stay.
6. If you are on electronic media such as computer or cell phone screen can be read many times to increase the text to the font larger.
