Until contact lenses were popularized in the 1950s, eyeglasses for the past seven centuries had been the only practical way to correct vision errors. Now, several modern approaches to corrective eye surgery range from laser reshaping of the eye's surface to surgical insertion of artificial lenses to correct eyesight. In corrective eye surgery, laser energy reshapes the curvature of the eye's clear front surface, the cornea, to alter the way light rays enter the eye. Artificial lenses surgically inserted into the eye also can refocus light rays to sharpen vision. In the surgery process, lasers are utilized to operate on the cornea and fix the parts of your eyes that don’t work, so that your eyesight becomes improved. The whole process of corrective eye surgery usually takes only a few minutes, depending on the patient’s present state of health. No matter how bad your eye sight was, after finishing the eye surgery treatment your eyesight result in a better vision. Many people are able to see things close up, far away or even perfectly. A condition where a person’s uncorrected vision is only clear up close is myopia. Instead of the light focusing on the retina, it focuses in front of the retina. A myopic person can read a magazine, however their distance vision is blurry. Hyperopia, commonly referred to as farsightedness, is when a person sees better in the distance than at near. Light entering the eye focuses behind the retina placing a blurry image on it. A person is emmetropic when an image focuses clearly on the retina allowing them to have uncorrected “normal vision”.

important vision was so I used my eyes pretty much and lost most of my eyesight. I used to watch TV everyday, play pc games and stay up late until I get tired. Now, I regret for what I?ve done to my eyes and hopes I can bring back my vision.

I used lots of things to help me see better such as, eye contact and glasses but didn
Laser surgery Lasers (The word laser is an acronym for light amplification by stimulated emission of radiation.) lasers were first introduced in 1960, The first successfully optical laser constructed by Maiman (1960), was a ruby crystal surrounded by a helicoilal flash tube enclosed within a polished aluminum cylindrical cavity cooled by forced air. The ruby cylinder forms a Fabry-Perot cavity by optically polishing the ends to be parallel to within a third of a wavelength of light. Each end was
(Everest College) What is Astigmatism? Astigmatism is a refractive error which could be all myopic (nearsighted) hyper opic (farsighted) or both mixed in the eye. Which can cause blurred vision, irregular eye curvature. The front side of your eye (cornea) is curved differently than in the other directions. Other areas of the eye may be more flat or steep. The 2 most common astigmatisms are 1) Corneal Astigmatism: cornea has an irregular shape 2) Lenticular Astigmatism: the lens has an irregular

Whether one chooses a simple solution such as glasses or contact lenses or opts for a more complicated answer such as surgery or implantable contact lenses is entirely up to the individual.

In 1998, the Lasik surgery became the most common type of surgery, and remains the number one refractive eye surgery

There is a type of albinism that only affects the eyes that make the irises very pale to not very existent this is called ocular albinism.

Photorefractive Keratectomy Myopia is defined as nearsightedness, which exists when the refractive elements of the eye (cornea and lens) place the image in front of the retina. The myopic condition is common in infants but generally levels off to normal vision as the infant ages (Vander & Gault, 1998). Myopia occurs in about 25% of the adult U.S. population. Many adults use corrective lenses or contacts to correct their myopic vision to 20/20 vision (Drexler et al., 1998). Many people find contacts

vision simply means that at a 20 ft. distance a person is able to see a certain letter than an average eye should be able to see at that distance. You can have 20/20 vision and lack the abilities to use your two eyes together as a team, to judge distances, to identify colors and to coordinate your eyes with hand and body movements. About four in ten people have "perfect" vision. There are also various eye disorders associated with eyesight such as astigmatism, farsightedness, and nearsightedness. Astigmatism

Graves Disease Jalen Jole Bio 202 What is graves disease? Graves disease also known as toxic diffuse goiter is an autoimmune disease that attacks the thyroid gland located in the neck. This gland regulates every day functions such as mood, mental and physical energy, and weight. It does this by releasing T3 and T4. When the gland begins to make too much of these hormones it is known as hyperthyroidism. Graves disease is usually the most common cause of hyperthyroidism and can lead to many issues
