Before 1887, people relied on spectacles as their main source of vision correction. It is unknown when spectacles came to existence, however, the “oldest known lens were found in the ruins of ancient Nineveh” (Drewry, 2001). Spectacles were magnifying glasses, used to make objects appear larger than its actual size. Not only were spectacles magnifying glasses, they were also used by the Chinese to protect your eyes from evil forces (Drewry, 2001).
The majority of Europeans were self-conscious about wearing spectacles in public. Spectacles, on the other hand, were popular in Spain. All classes in Spain wore spectacles because it “made you look more important and dignified,” (Drewry, 2001). In the 1840’s, spectacles were worn as an accessory by both men and women throughout Europe.
Spectacles gave a person good vision if a person had a regular cornea and normal astigmatism. However, if a person had “corneal astigmatism or diseases and abnormalities of the cornea” the productivity of the spectacles were minimal (Siviglia, 2010). Little did people know that contact lenses would be developed and help individuals who did not have regular corneas and normal astigmatism.
Contact lenses were first introduced during the Renaissance by Leonardo Da Vinci. Da Vinci was interested in the human eye as well as the human body. His purpose for contact lenses was not to help a person with vision problems, instead, Da Vinci was looking for a way he could manipulate the cornea’s power (Swaby, 2011). Through Da Vinci’s experiment, placing his face into a bowl filled with water, he discovered that he was able to see clearly for the first time (Siviglia, 2010). Da Vinci then created a “contact lens with a funnel on one side so water can be poured in...

In the novel Tangerine, Paul Fisher wore huge glasses to help with his vision. In the novel Paul said, “But right after the eclipse, I was wearing these thick lenses that I now call my regular glasses” (Bloor 34). Erik ruined Paul’s eyes by holding his eyes wide open for Vincent to spray paint Erik replies after, “ Arthur takes care of my light work” (Bloor 212). One day, Tino came over to Paul’s house to work on a project. Erik came home to find Paul and Tino outside in the backyard.

Optometry involves of a combination of intricate practical skills and academia allowing the improvement of an individual’s vision as an outcome changing their quality of life. I would feel privileged to gain the opportunity to study Optometry enabling me to improve the ocular health and vision of others as it would be a valuable contribution to the society.
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

No, not "Why am I going to class so early?" but "Why do I need these contacts?" With this project I will attempt to explain the basics of vision and corrective lenses, as I, myself, finally learn the reason for sticking my finger in my eye every morning.

Although telescopes has been around for several hundreds of years, there has been great discrepancy as to who invented it first. Here is one authors opinion. Lippershey was a Dutch spectacle marker during the early 17th century (approximately 1600). He was one of the first who created the "looker" (now called telescope) by placing two pieces of lenses together. The discovery that placing lenses together can magnify images were made by children who took Lippershey's spectacles and looked at a distant church tower.
Ah, but there’s the rub. Sometimes I wear them, sometimes I don’t. I wear glasses when I read, because contacts dry out my eyes too fast. I wear glasses when I relax, or when I take a shower. On the other hand, I wear contacts when I play sports or get a haircut. So I guess my problem is simply this: I’m both glasses and no glasses.
When the contact lens was invented, the world of vision correction was altered forever. No longer were those people lacking perfect 20/20 vision forced to look any different than everyone else. Both discrete and revolutionary, the contact lens provided a brand new, viable, alternate solution to an age-old problem. After centuries of engineering and discovery the contact lens has evolved greatly. Presently contact lenses are made hard or soft, for daily or continuous wear, gas permeable, and even providing ultraviolet protection. A properly fitted pair of today’s discrete, convenient, versatile, and inexpensive contact lenses provide the best form of vision correction available in today’s market.
