If you are like me, you have a great passion for contact lens use. I wear lenses on a daily basis, but my problems with vision correction go way back. When I started wearing contacts, I had no idea what to do. I found that I could not get the magnification that I wanted from the eyeglass lenses that I was wearing. The technology was so new that the only way to correct my vision was through contacts.
In the early 1900’s a man named James Braid invented the bifocal eye care. He came up with a way to improve upon the typical contact lens that we are familiar with. His solution to the issue of nearsightedness involved the use of two separate prescriptions that were placed one in front of the other in a frame that was worn on the eye. Each of the prescriptions worked to correct a specific focus of visual acuity. This was the first step to the current method that we use today. This particular design typically works better for people that are more naturally oriented than those that are really into precision.
The modern design of contact lenses is one that features a single prescription in a single housing. This allows for the same high precision as the original design, without the need for eyeglasses or contact lenses. A single lens is called monovision and the term refers to a single lens designed for one eye. The other term for monovision is ocular. These lenses are used primarily for special purposes rather than for nearsightedness or farsightedness.
The next trend that I would like to discuss is the color of the lens. The traditional trend for most contact lens wearers has been towards either a neutral color, such as brown, or towards a specific color, such as a special colored contact lens. Today however, there is a trend towards the colored contacts. There are even some eye colors that are becoming considered normal.
The third trend that I would like to point out in the discussion of new fashions in contact lens use is the development of corneal epithelial cells. These cells are typically found in the outer layers of the cornea, where they are responsible for keeping the eye tissue nourished and protected. With the advent of more advance microkeratitis drugs, the removal of these cells may help alleviate some of the vision problems associated with keratitis.
In order to keep the lenses from rubbing against the cornea and irritating the eyes, it is recommended that lenses be worn on an extended term basis. Wearing the contact lens overnight is typically not advised due to the fact that they can become uncomfortable over the course of the night. People that typically wear contact lenses on an overnight basis are typically those that typically have dry eye syndrome. Additionally, people who typically wear soft lenses on an extended period of time are typically those that typically have eye sensitivity, which makes them a bit more sensitive to the discomfort that can come with contact lens wearing.
