Can you see this? I guarantee you can, otherwise you wouldn't be reading this sentence. But what is the importance of those questions? Well, the better question is, how do you define a “contact lens”, or “contacts”? Well, Urban Dictionary defines the normal everyday, prescribed contacts as being small pieces of plastic (which these days are usually pretty soft, as compared to the older, stiffer "hard" contacts) which are basically stuck on your eyeball as a replacement for glasses. They have grown in popularity in the last several years, to the point where many people have them because they a)find them better than glasses or b)think they'll look cooler without their glasses. Circle lenses, however are defined by Urban Dictionary as, A type …show more content…
Well...why not start with the question, why are they illegal? Well, the FDA won't allow circle lenses to be sold in the USA because they're made overseas. The FDA hasn't banned them, per se, but they have not approved them for sale in the States. The reason it's not FDA approved is because most circle lenses come from overseas and therefore, well, can't be regulated by OUR FDA. But every country has it’s own ‘FDA’ so to speak. And lenses sold from each country are usually inspected by said ‘FDA’ to ensure quality, and safety. Karen Riley, a spokeswoman for the F.D.A., was a bit surprised, too. When first contacted, she didn’t even know what circle lenses were or the extent to which they had caught on. But soon after, she wrote in an e-mail message, “Consumers risk significant eye injuries — even blindness” when they buy contact lenses without a valid prescription or help from an eye …show more content…
Circle lenses are not to be used on a daily basis, and most complaints as far as damage to the eyes are from misuse or prolonged use, just as if one was to overuse standard issued reading glasses. It’s been noted that if and when someone starts having eye issues it’s mostly due to things like them being low-quality, buying them from the wrong place. “They are just as dangerous as regular contacts, and actually, the circle lenses I buy are 10 times more comfortable than my regular contacts.” AshofRebirth continues “I have seen one case of circle lenses leading to injury that came from something that wasn't misuse.. You can do that with any regular contacts.” Another user on the same website, Vervv, said “Circle lenses are (for the most part) not made in the US, which is the main reason. If the lens is a low-quality, knock-off lens then you risk damage to your eyes through malfunction of the lens or infection of the eye. Because the FDA cannot regulate the factories producing the lenses overseas, they cannot ensure the quality and are therefore not
the globe. However, this code makes no mention of corneal disease, scarring, or any condition requiring treatment that might be used to improve vision that is deficient because of corneal disease. Health New England’s Clinical Review Criteria includes a list of conditions of the eye for which scleral contact lenses would be approved for coverage, as follows:
Sof-Optics is a small (specialty-niche) player in a $155M contact-lens market. (Three competitors occupy 75% of this market (Bausch + Lomb (51%), American Optical (14%), Continuous Curve (10%); approximately twenty players (including Sof-Optics’ ~3%) occupy the remaining 25%.) This consumer space is already appreciable in size (~5M contact-lens wearers in 1980), and promises exponential growth in future years (only 10% of ~50M prospective lens-wearers in America have even tried soft contact lenses).
It is necessary to have a contact lens fitting in order to wear contacts, whether you’re planning on wearing them one-time or you’re completely transitioning from wearing eye glasses, there is more to it than just getting a prescription and deciding which contacts you want. Just as one shoe size doesn't fit all, one contact lens size doesn't fit all. If the curvature of a contact lens is too steep or too flat for your eye's shape, it could be uncomfortable or even cause damage to your eyes.
“It is amazing to me that, despite the variety of beautiful contacts lenses that have been developed today, people will still come up to me and compliment my eyes, often asking if they are real. One memory that I have kept with me is of an old lady who was partially blind but when ever she’d see me, she’d grab my arms, peer right into my eyes and then a big smile would break out on her face and she’d say, “Blessed child. You have beautiful eyes!” The old lady – unfortunately I never learned her name, she was always Ma’am to me - was the sister of my close friend’s mother and had come to Canada from Lebanon to visit a friend. She’d walk around her block and my friend and I would often encounter her on our own excursions. I never really knew

In addition, symptoms of eye infection has include blurry vision, unusual redness of eyes, painful of eyes and tearing of eyes, so it causes loss of vision to blindness. Thus, some people have symptoms of eye infection who people must have to meeting
Paris optician, Edouard Kalt created and fitted the first glass contact lenses to correct vision
Product substitute: The possible substitutes for optical glasses are contacts and eye surgeries, while sunglasses are difficult to be replaced. Consumers will face certain switching costs if they turn to substitutes (contacts, surgery, etc.).
Eye protection; such as spectacle/goggles to prevent dust or any other harmful substances from your eyes.
Convenience: When the weather is nice, people will engage in a variety of activities. There may come a time or two that wearing glasses just becomes an inconvenience because they fall off of your face, need to be cleansed or just aren't fitting properly. Contact lenses are convenient because you don't have to bother with them once they are in. You can go about your day and enjoy whatever activity without having to adjust, clean or wipe them.
Relevance Statement – For most people they feel that they can see so they don’t need their eyes checked, when in reality that statement is false.
Imagine pricking your fingers with a needle five times a day. As a type 1 diabetic, this is a reality for me. My fingertips are callused and scarred. I was frustrated that after years of having diabetes, there wasn’t an easier way to check my blood sugar. I scoured Google Scholar for alternatives and I found a contact lens technology that would be capable of checking sugar levels using only tears. This would eliminate the need to prick my fingers for blood! If an unassuming tear could simplify diabetes care, what else the eye was capable of? My curiosity led me to volunteer as an optometry intern for blind motivational speaker Nancy Solari. Nancy is based in California and I live in Maryland, so I was a remote intern, communicating with Nancy
Eyeglasses were created in Italy by Salvino D’Armate during the late 1200s to help people who couldn’t see very well. The frames were made of metal or bone, and the lenses were made of quartz. During the 14th century the were called “disks for eyes”. The glass disks that were finely ground were named lenses because they looked like lentil beans. Early lenses bulged outwards in the middle, and were used for people who were near-sighted.
Do you need corrective lenses in order to see? Are you wondering whether switching to contact lenses might be right for you? Although you should discuss your decision with your optometrist, it's a good idea to get facts before going to see your eye doctor. This will allow you to ask better, more targeted, questions during your appointment. Here are the answers to some questions you might have about wearing contact lenses:
To open the contact lens case, one must twist or pop off the lid to the case. The same act is performed when opening the bottle of contact solution. After this, one must place the contact under the bottle
I looked into the physics of the eye itself and into corrective lenses because I wear glasses. The human eye is a very complex piece of anatomy. Like a camera, the eye is able to refract light and produce an image that can enable someone to see.
