| Signs of Aging Eyes |
Signs of Aging Eyes : Beware & Consult - Do you feel the change in your eyes, such as eye fatigue, soreness or easy to see at close range or long-range already not clear? It will be good from now on be sent to the eye doctor and perhaps the signs are the causes of eye aging. Decrease in vision with age is often complained of by many people. Even when I was quite young also have many people who have started to impaired vision.
Most people feel that when they reach the age of 40 years began to decline in vision, even if the sight before either. Decreased function of vision is the inevitable result of the aging process associated with chronic diseases or degenerative diseases. Some changes or decreases related to the sense of sight with age as quoted BBCHealth, among others:
1. Usually becomes more difficult to read, especially if the lighting is less.
It is called presbyopia and occurs due to changes in eye tissue. Especially the eye lens becomes larger and less flexible. Thus affecting the ability of the lens to focus. This can be corrected by wearing glasses with the appropriate size.
2. Dazzled
Glare can also be a problem as the changes in the lens of the eye. So change causes light entering the eye will spread so that the focus is not right.
3. Difficulty distinguishing colors
Some people also experience decreased color perception. So it becomes difficult to distinguish the different color shades.
4. Eyes become dry
Important changes in the eye associated with other age is that the eyes become dry. This is because the tears produced less and viscosity changes, so tears are less efficient in forming a protective layer that lubricates the whole eye.
At the same time various eye diseases and other conditions may start to occur, which can worsen the decline in visual function. Some eye diseases and other conditions, among others:
1. Glaucoma
Fluid continues to flow, in and out of the eye. However, in glaucoma, the flow out of the fluid inhibited. So that the pressure inside the eye increases. This 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 most often develops in older people, but prompt treatment can restore vision.
Cataracts develop when the older age. So it is called age-related cataract. Smoking and exposure to ultraviolet radiation is a risk factor for cataracts.
Other causes of cataracts include diseases such as diabetes, treatment with certain drugs, as well as inflammation and injury to the eye is too long. These symptoms are common associated with cataracts include blurred vision and vision cloudy or foggy.
3. Age-related macular degeneration
The macula contains a very high density of light receptors, especially the cone receptors. Cone receptors are receptors that can detect colors. So that the macula is very important to see fine detail on an object directly opposite.
The macula plays an important role in helping to read, write, drive, and perform other detailed tasks. It is also possible to recognize faces and see colors. AMD can lead to loss of central vision. There are two types of AMD, among others:
4. Diabetes
Diabetes is one cause of cataracts. Many elderly people with a history of diabetes, so that it can exacerbate the decline in vision occurs.
5. High blood pressure (hypertension)
Hypertension can cause the heart to work harder than usual. Thus causing the heart and arteries have a greater risk for damage.
Hypertension can increase the risk of heart attack, stroke, kidney failure, eye damage, congestive heart failure, and atherosclerosis.
To address the decline of vision related to the older ways, among others:
1. Perform an eye test at least every 2 years and always make glasses in good condition.
2. Consult a doctor for problems such as high blood pressure or diabetes, as well as taking medication as recommended to prevent damage to the eye.
3. Using reading glasses or bifocal / varifocals.
4. If you want to read, before ensuring that the lighting is good enough.
5. Use eye drops or artificial tears to keep the eyes lubricated and comfortable stay.
6. If you are reading in the electronic media, such as computer or mobile phone screen, can enlarge the text to be larger font
