Ever since I was in the 3rd grade, I had to wear glasses. I was diagnosed with astigmatism in both eyes. What exactly is astigmatism? Well, in a perfectly-shaped eye, the cornea, or surface layer, is a sphere, like a baseball. It allows light to enter your eyes at the right angle and focus just so on the retina. That means your vision is sharp and crisp. With astigmatism, the cornea shape is more like a football than a baseball. This irregularity makes the light rays focus on two points on the retina, not one. This causes blurry, distorted vision. Eyewear is a huge part of my life. Without my glasses or contacts, I am unable to perform at my best. If I have dry eyes because of my contact lenses, “like many contact users after the end of the day,”(Best), it unables me to accomplish certain tasks. Also, without the proper eye care, I could suffer an infection just as “William Spadafora, who suffered from a nasty fungal infection called, Fusarium,”(Kennedy). In certain states, the prescribing practitioner is required to give one their eyewear prescription.
This eyewear prescription policy developed in 1978, when the Federal Trade Commission action known as Eyeglasses I concluded, the subject of

“The FTC enforces the Eyeglass Rule and Contact Lens Rule, which give you the right to get a prescription from your eye doctor – whether you ask for it or not – at no extra charge. That allows you to shop around and look for the best deal,”(Prescription Glasses and Contact Lenses). In the state of Iowa, the Iowa Legislature states that, “after the contact lenses have been adequately adapted and the patient released from initial follow-up care by the prescribing practitioner, the prescribing practitioner shall, upon request of the patient, provide a copy of the contact lens prescription, at no cost, for the duplication of the original contact

Optometrists have accepted vision therapy, which is a medical treatment for optical muscle disabilities, as a feasible treatment used for eye related problems; claiming the treatment can strengthen vision and give the patient the opportunity to understand visuals quicker and clearer (Press). Vision therapy originated in the 1950s and over the past 25 years, has gained popularity, mainly because of new technological innovations in the field of treatment. Generally, vision therapy is prescribed as a measure mainly for people between the ages of 3 and 18. With the results from a comprehensive series of eye tests, the optometrist can work with the patient using special instruments—prisms, filters, occluders, and eye lenses—and strengthen the eye muscles, thus improving sight. According to optometrists in favor of vision therapy, these methods of treatment using these instruments function as safer routes to repair eye disabilities. Although vision therapy can yield favorable results, the practice as a treatment for innate eye disabilities has been in hot debate lately; as it can exceed $8000 and insurance companies do not cover the treatment. For decades, insurance companies have refused to accept vision therapy as a legitimate method for repairing eyesight (Boink). Concomitant with lack of insurance, the cost for a full treatment can exceed $8000, and doctors cannot guarantee a successful outcome. Recently, parents of children with eye related disabilities, such as amblyopia (lazy eye) and strabismus (cross-eye), and doctors have attempted to cooperate with public schools to allow families access to school-funded doctors to practice vision therapy. With a tight budget, most schools cannot afford to supply vision therapy, and a...

Glaucoma is a common and important health problem. It is one of the leading causes of blindness in Western Society (Hoskins & Kass, 1989). It is responsible for ten percent of all blindness in the United States and continues to be the second or third most common cause of blindness in the world (Bunce, Fraser, & Wormald, 1999). It is estimated that two million people in the United States have been diagnosed as having glaucoma. Glaucoma is known to affect about two percent of Caucasians beginning at the age of 40 with an increasing risk for those over the age of 60. This risk is especially high if a member of the family has glaucoma or diabetes. Further, there is a higher risk of a glaucoma diagnosis for African Americans over the age of 40.
As humans age, they frequently develop a condition known as presbyopia. This condition decreases the person's ability to focus sharply on those object which are nearby and is the result of the lens of the eye hardening. In addition, astigmatism requires a person wear prescription eyeglasses and/or contact lenses. Astigmatism arises when the curvature of the eye is irregular. The eye is normally shaped liked a soccer ball or basketball. With astigmatism, it takes on a more oval shape and resembles a football. Due to the irregular curvature, the eye processes light differently and leads to blurred vision. The degree of blurriness is determined by the degree of
People that have problems with vision due to albinism can’t fix their vision completely with glasses or contact lenses. The problems start in the eyes with poor development. Albinism reduced the pigment of the colored part of the eyes (iris) and the light sensitive tissue at the back of the eye (retina). They will not see things sharp and will have fast eye movement that can’t be controlled (nystagmus) and very sensitive to bright lights (photophobia). They could also have...
Amblyopia is a condition in which visual acuity in one eye is greatly reduced. It is caused by lack of stimulation or disuse during visual development (Rose, 1998). Because the eye is not fully developed at birth (Jarvis, 1992, as cited in Rose, 1998), infants need stimulation to complete the visual neural pathway. When one or both eyes are inhibited, for example due to misalignment of one eye (strabismus) or a large difference in refractive power between two eyes (anisometropia), the neural pathway for the inhibited eye develops abnormally, or does not develop at all. At approximately six years of age eye development is complete (Stager, 1990, as cited in Rose, 1998). Before visual development is complete amblyopia can be treated. If it is caught and treated at an early age, normal vision can be preserved (Rose, 1998).

...he cornea is deformed so that its surface is oval instead of spherical. Light rays are distorted at the entrance of the eye. This produces a blurred image and is known as astigmatism. To correct it, glasses are given a nonspherical or cylindrical curvature. Cross-eyes and walleyes are produced when both eyes do not work together because of weakness of the eye muscles.
