Early Stages Of Cataract

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.

The dry form is broken down into three stages; Early, Intermediate, and Advanced (National Eye Institute 3). In the Early stage, people have several small or few medium yellow deposits under the retina called drusen. This stage shows no symptoms or vision loss. During the second stage, Intermediate, more medium or even large deposits happen. As this happens, a blurred spot can develop and more light could be needed for reading. Lastly, in the Advanced stage, a breakdown of light-sensitive cells and tissue causes the blurred spot to enlarge and darken. In this latter stage, facial recognition is unlikely unless the person is extremely close. Either form of Macular Degeneration can only be detected by thorough eye exams. The exam should include visual acuity, which measures sight at varied distance intervals. Also, dilation of the eyes will allow an ophthalmologist to check the retina and optic nerve. An instrument called a Tonometer will measure pressure within the eyes (National Eye Institute 6).

According to the American Optometric Association, when "you reach your 60s and beyond, you need to be aware of the warning signs of age-related eye health problems that could cause vision loss. Many eye diseases have no early symptoms. They may develop painlessly, and you may not notice the changes to your vision until the condition is quite advanced."

Patients with age-related macular degeneration may not notice any symptoms at first. The first noticeable sign is a gradual, or sudden, change in the quality of vision depending on which type of AMD is occurring. Straight lines will start to appear distorted (Kozarsky, 2017). Early dry AMD is diagnosed by the presence of drusen. This gradually can cause a dramatic loss of the center of vision. In the intermediate stage of AMD, the beginnings of vision loss are apparent, but there still may not be any other noticeable symptoms. At this time, optometrists will test for larger drusen and pigment changes in the retina (“Research into the Genetics of Macular Degeneration,” 2017). Other symptoms of age-related macular degeneration might include an

Glaucoma is a group of eye diseases characterized by increased intraocular pressure, resulting in atrophy of the optic nerve. (Venes, D. 2013) This disease is known to gradually cause the loss of peripheral vision which can eventually lead to total blindness. Glaucoma is the third most prevalent cause of visual impairment and blindness in the U.S, although the incidence of blindness is decreasing due to early detection and treatment. (Venes, D. 2013) Glaucoma comes in two major categories: closed-angle glaucoma, and open-angle glaucoma. (Holistic Nursing Practice, Vol. 24)

Some people have slow-growing cataracts and they may not need any treatment at all. If you have fast-growing cataracts, you may notice a gradual decline in your vision. You'll need bright lights to see well and your vision may be blurry. In addition, you might see halos around lights and your night vision will be impacted. If the cataracts get bad enough, you may not be able to drive or do many activities of daily life due to poor vision.

In it, there are multiple kinds. The first, and more common, is open-angle glaucoma. This is the version that at first causes no symptoms, but then causes peripheral vision loss and sometimes total blindness. The second, less common version, is angle-closure glaucoma. Acute angle-closure glaucoma is when the flow of fluid between the lens of your eye and your cornea is blocked. It can induce severe pain, nausea, vomiting, blurred vision, and rainbow halos around lights. Blindness can result in under two days from this version. Another version of angle-closure is chronic. This is like acute, but it produces damage without symptoms

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

Posterior polar cataract can lead to amblyopia as these type of cataracts often present in the first few months of life. Most posterior polar cataracts are stationary but can progress in severity over time. (3-5)

The other type of macular degeneration is “ wet”, it is known to be the most severe of the two, it occurs when there is “

A research conducted at the University's Center for Chemical Genomics points to a chemical that can reverse cataracts, one of the leading causes of blindness in the world. The molecule (compound 29) belongs to the chemical family of sterols and the research was published in the November 5 edition of Science. It is to be noted that cataracts are one of the leading cause of blindness in the world, affecting several thousands of people.

Accommodation and convergence allow us to see objects clearly both near and far without needing double vision. Accommodation is the ability to focus on close vision. Convergence is the movement of the eyes when focusing on close objects. Emmetropia is normal eyesight. Myopia is nearsightedness. It is when you have too much focusing power. Light focuses in front of the retina and make the far vision blurry. Hyperopia is farsightedness. This is when the eye is short and not enough focusing is happening. Light coverage is behind the retina and causes close vision to be blurry. Having liquid in your eyes, some of it drains into holes and then into lacrimal sac then going into the nasolacrimal duct, and into the back of your nose and/or throat

Cataracts is an eye condition caused by a buildup of protein in the eye. Although it can occur at any age, it is far more common in those who are 75-years old—or older. If your parent or loved one is suffering from cataracts, they will likely need surgery to correct the problem. Although the recovery time is not very long or painful, your loved one will likely need help for the first few hours—or days—after the surgery.

Vision challenge or impairment is when a person’s degree of seeing is very low and the affected person requires assistance in order to carry out daily routine. Significantly, for one to qualify as visually impaired there must be prove that a person cannot undertake duties by himself without necessary assistance. For a person to qualify as a visually challenged, there must be a prove that the affected eyes cannot be conventionally treated. Visual challenge cannot be corrected by surgery, refractive measures neither by medication and that is why it is termed as visual impairment. The most rampart causes of visual challenge are trauma, degenerative or congenital means and a variety of diseases. In the society,

When your cataracts get to a certain stage, you'll begin to have problems with glare from sunlight and you'll probably see halos around street lights. That means it will be unsafe for you to drive at sunset and after dark. Your regular vision may not be affected too much yet, so you may want to postpone your surgery. In that case, you'll have to give up driving at night, and that could affect the quality of your
