Eyeglasses have two main lenses. This includes a convex lens for nearsightedness, and a concave lens which is for farsightedness. With both lenses the light hits the glasses and bends inward or outward (depending on your circumstances; nearsightedness or farsightedness) According to LL. Woodward, many people say that contact lenses fulfill both nearsightedness and farsightedness. “Thanks to the advent of multifocal contact lenses, people with both vision conditions-presbyopia and myopia-now have the option, and the freedom, to choose to wear contact lenses only to improve their vision” - LL. Woodward. From my recent questioning to students with contacts, there are two different types of contacts; one is to sleep with and you can see the rest of the day without them and ones that you wear throughout the day.
There are many companies that distribute used glasses to people. I’m choosing Lions Club International as an example. In Lions Club International, people either mail or place their old glasses in a box. These glasses are fixed up and given prescriptions.

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...

My interest in the career of optometry stems from my first experience in the optometry office to receive my first pair of glasses when I was in middle school. I distinctly remember the moment when my optometrist slipped my new glasses over my eyes for the first time. Suddenly, everything in the room came into sharp, clear focus. I knew that the glasses would help me see the board in school, but I was astonished to find that I could see small details about the room, as it had never before occurred to me that I should have been able to see these details. I was also surprised that I was even able to see the expressions on the faces of people who were standing far away from me. It was one of the most incredible, freeing, and empowering moments of my life. As I walked out of the optometry office, I felt

Over the past few years, many success stories have emerged as a result of assistive technology. ESight proves to help thousands of visually impaired individuals “see clearly” for the first time. From seeing a mother for the first time, to watching a favorite sports team or meeting the Easter bunny, eSight has changed the lives of thousands of people ranging from ages four to 101 years old. This includes Gary Foster, who lost all central vision in both of his eyes as a result of macular degeneration. He could not identify a peanut on a table, much less a person’s facial expression or words on a page, but with eSight, his vision was transformed. “When he put [the eSight eyewear] on, he realized that his vision drastically improved, so much so that he could see faces and read books.” So many people just like Gary Foster can benefit from this technology. Similarly, sighted volunteers and visually impaired users recognize the usefulness and success of the Be My
One reason is that recycling can help save the earth from waste and trash build-up. For example, fifty percent of roofing and construction on houses is made from recycled aluminum cans. Using recycled materials to produce new products costs less money and less energy than new materials. It can also save valuable landfill space. People have trash everyday. Pretty much anything is recyclable. If you throw them away, it?s a waste of natural resources, a waste of energy, and a waste of money. Instead people should take the time collect these things and put some effort into helping in the world we live in.
