How Cataracts Affects The Power Of Vision

The cataracts within the eye often changes in the lens of the eye. As people grow older the lens in the eye starts to change and can start to appear cloudy looking, this often happens and stops the process of the eye lens from being able to change shape or even to transmit the light properly. The cataracts may start to form between the ages of 50 and 60 years old and can often take a while to develop. If you are known to have diabetes then that also contributes to poor cataracts.

Visual impairment is a state wherein an individual experiences difficulty in seeing or not being able to see anything physical presented to them. According to Mandal, MD (2013) It is a state where a visually impaired person’s eyesight cannot be corrected back to a “normal level”. Visual impairment is often associated with old age. In Europe, an estimated 15.5 million people have visual impairment and in seven countries in Europe, about 50% of blindness is caused by age-related macular degeneration. (Dibb,

“The doctors told me that cataracts is when the lens of your eye gets cloudy and that is why I couldn’t see,” Matthew said.

Glaucoma is several conditions of the eye that damage the optic nerve, which is vital to perfect vision. This damage is caused due to an abnormally high pressure in your eye. Glaucoma is one of the leading causes of blindness in the United States. It can happen at any age but is most common in older adults. If you lose your vision due to glaucoma, it is not possible to gain it back. It is important to get regular eye appointments because if glaucoma is caught early, the loss of vision can be slowed or prevented. There are two types of glaucoma. Open-angle glaucoma and acute angle-closure glaucoma. The symptoms for these two are very different. Open-angle glaucoma symptoms include patchy blind spots in your central or side vision,

Glaucoma is several eye conditions that can damage to your optic nerve. Increased pressure in the eye can cause glaucoma, which leads to vision loss or blindness (Healthline). There are five different types of glaucoma, which are open-angle (chronic) glaucoma, angle-closure (acute) glaucoma, congenital glaucoma, secondary glaucoma, and normal-tension glaucoma (Healthline). Open-angle (chronic) glaucoma is the most common type of glaucoma, and there are no signs or symptoms expect gradual vision loss (Healthline). People that over sixty years old are at risk for glaucoma, and African Americans risk starts at forty years old. There is no cure for glaucoma, but surgeries and medicine can help

Do you know what the leading cause of blindness is in Americans from ages 20 to 74? It is diabetes an illness that changes the way the body breaks down and absorbs sugars. These changes, doctors feel, take away oxygen that the retina needs. (The retina is the back layer of the eye and it is where sharp images are formed.) When this happens’ some small blood vessels may become weak and break, vision problems occur when this blood leaks into the areas around the retina. Diabetes can also cause glaucoma and cataracts. Glaucoma is a disease that causes a lot of pressure in the eye because too much fluid builds up. Cataracts, on the other hand, cloud the lens of the eye and this makes a person feel like he or she is looking through a grimy window.

It’s usually a buildup of pressure inside your eye. Glaucoma tends to be inherited and may not show up until later in life. The increase pressure, called intraocular pressure, can damage the optic nerve, which transmits images to your brain. If the damage continues, glaucoma can lead to permanent vision loss. Without treatment, glaucoma can cause total permanent blindness within a few years. Most people with glaucoma have no early symptoms or pain. People need to see a eye doctor regularly so he/she can diagnose and treat glaucoma, before long-term visual loss

According to Baily and Hall, while visual impairment early in life is associated with inherited congenital disorders, abnormal fetal devepment, and problems associated with premature birth, most eye conditions are associated with aging. They claim that over 70% of the visually impaired population in the United States is over 65. Age related maculopathy, also called macular degeneration, or AMD, impairs the center of vision in older individuals. The macula is the region in the back of the retina that surrounds and includes the fovea (Goldstein 1999). It is important to understand that when this degeneration progresses enough, the condition constitutes blindness because the foveal area is what is

Secondary glaucoma’s can progress as complications of other medical conditions. For example, a severe form of glaucoma is called neovascular glaucoma, can be caused by uncontrolled diabetes or high blood pressure. Sometimes with cataract, eye tumors, or with the inflamed or irritated eye by a condition called uveitis. In some cases, glaucoma progress after eye surgeries or serious eye injuries. In a few people drugs like steroids to treat eye diseases can cause glaucoma. There are two eye conditions are searching for secondary forms of

One condition your optometrist checks for during your regular eye examination is cataracts. A cataract causes clouding of the lens of your eye. You can have cataracts in both eyes or just one. A cataract can form in the center of the lens or along the edges. It may not interfere with your vision in the early stages, but your optometrist can detect it during an examination. Here are a few things to know about cataracts.

A cataract is a clouding of the lens of the eyes, causing the vision to be blurry. It is caused by protein clumping together in the lens forming a small clouded area; even though it isn’t painful within time, it can grow larger making it harder to see. It is commonly found in older people. It can occur in either or both eyes; however cannot spread from one eye to another. In age-related cataract can affect your vision in two ways—clumps of protein or lens slowly colors with age.

Eye color comes from the amount of melanin, a pigment found in the front part of the iris of the eye (Genetics, 2017). Lack of melanin results in blue eyes, some melanin gives green eyes, and a lot of melanin gives brown eyes. Cataracts are clouding of the lens that prevents light from entering. The cause of cataracts is unknown but there are possible reasons for it such as diabetes, smoking, and a lot of exposure to sunlight. Signs include lack of color intensity, night vision problems, fuzzy, blurry, or filmy vision. The function of the retina is to receive light the lens had focused on, switch the light into neural signals, and then send those signals to the brain for visual recognition. Most of the time eye floaters are from age related

     Really the cause of Macular Degeneration is unknown. Recently researchers have discovered that a group of genes called ABCR contribute to the disease. When someone has these genes the likeliness of this person to form Macular Degeneration increases by 30 percent. In most situations Macular Degeneration is

If you're experiencing cloudy or dim vision that has gotten worse over the years, you may have cataracts. Cataracts tend to get worse over time, and they can even cause you to lose your sight entirely. Fortunately, diagnosing and treating cataracts is fairly simple. It all starts with an eye exam. Here's what you can expect.

Glaucoma is a group of eye disorders that cause blindness by hurting the optic nerve, which is the large nerve that is responsible for vision. In glaucoma, the optic nerve damage is related to a change in the fluid pressure that circulates around the eyeball. In many cases, Glaucoma occurs when the eye's fluid pressure is high, but it can also occur when the pressure is measured as normal.
