Blurry vision is extremely common. Many individuals experience some degree of blurriness when they are reading, watching TV, or even looking at a computer screen. Often times this blurring occurs after age 35, but it can be experienced by anyone. Sometimes it manifests itself in a negative way, as you may see nearsightedness, farsightedness, presbyopia or astigmatism. No matter what your age is, blurred vision can be extremely disfiguring and embarrassing.
One of the most common symptoms of blurry vision, or even chronic dry eyes, is dry eyes. Dry eye syndrome is not actually a disease, but rather an uncomfortable condition brought on by the condition known as dry eye syndrome. It occurs when there is an abnormal buildup of tears in the eye. This condition is most commonly found among children and often accompanies the other difficulties of childhood like soreness and redness of the eyes, as well as itching and discomfort in the eye area. As the condition advances, symptoms include burning, stinging, and even pain. Because these dry symptoms can be so irritating, many sufferers become frustrated and lose sleep.
Blurry Vision and Glaucoma One of the leading causes of blurry vision, glaucoma is often a factor that manifests itself with crossed eyes or extreme sensitivity to light. Glaucoma often causes partial blindness in one eye. With crossed eyes it leaves the one eye completely free of sight, while in the case of glaucoma, complete blindness in one eye is possible. While both conditions are extremely serious, there are some treatment options available to treat them.
Glaucoma causes blurry vision by blocking the visual channels in the macula, which is the area that produces the pigment that makes color visible. The symptoms of glaucoma appear in four stages, with the first stage occurring during early development and continuing into later stages. A raised intraocular pressure along with a reduction in the drainage of fluid from the eye is one of the common symptoms of glaucoma. In advanced glaucoma, the pressure and fluid flow reduce to almost nothing, resulting in the loss of vision. Other causes of blurred vision include the accumulation of internal bleeding, hypertension, and an angle-closure glaucoma, which result from a closed angle in the iris. Treating glaucoma can be difficult, because the angle-closure glaucoma is not usually dangerous, but it cannot be cured, and must be managed for the rest of your life.
Another condition that causes blurry vision may be due to vitreous eye floaters. People who have vitreous eye floaters are normally normal, healthy people whose eyes are perfectly healthy. However, some people with vitreous eye floaters experience problems that include eye floaters and headaches.
The sudden blurry vision is one of the most annoying and embarrassing symptoms of many different eye conditions. While there are treatments available, it is important to understand the causes of blurry vision in order to treat the symptom correctly. Remember that if you experience any other symptoms that are similar to those listed here, such as blurred vision, headache, sudden blurred vision, dry eyes, itching or watery eyes, or eye redness, you should visit your doctor immediately to rule out any serious underlying eye problem. Your doctor will be able to give you more detailed information about what you need to do in order to improve your eyesight and prevent the condition from getting worse.
If you have been diagnosed with presbyopia or farsightedness, you will also find that you suffer from blurry vision. While both conditions are caused by a strain on the eyes, they are very different. Farsightedness is caused by the loss of central vision, whilst presbyopia is caused by the deterioration of the retina. This means that when your eyes are tired or fatigued the natural healing process of the eye slows down and this eventually leads to blurred vision. As well as this, stress, lack of sleep and ageing are also some of the causes for presbyopia and can be a contributory factor in treating your own presbyopia.
Cataracts are another cause for blurred or clouded vision. Cataracts occur when fat deposits build up on the lens or retina of the eye. When there is too much water in the eyes, they may float and become impacted by the crystalline deposits which is what causes the blurred or foggy vision. Cataracts can grow on their own, too, and they will continue to affect your vision as long as they are in place.
If you have a problem with blurry vision, take care of it immediately. Do not wait for the condition to worsen because you will be compromising your eyesight permanently if you do so. You should consult with a qualified optometrist who can help you determine the best treatment for you. In most cases, your optometrist can prescribe contact lenses and glasses.
