Health Risk perception?Some information on [percieved] health risks of regular contact-lens wear? AdvertisingHow about removing the "Contact lens review" link at the bottom? It appears to be a blatant attempt at advertising. --Joeljkp 16:30, 29 July 2005 (UTC)
Health risks? images on commonsI uploaded these on commons this morning, might be more interesting licence then te one currently used. Henna 09:04, 14 August 2005 (UTC) Image:Lens.jpg Image:Lens2.jpg Opening paragraphHow about removing the 'atop the iris' part? Could be confusing and is redundant as we've already stated it is placed 'on the cornea'.
ClarificationHow about a paragraph on how they actually work? I have heard from friends that they supposedly change the shape of the eye by "pressuring" it into taking the correct shape. I am fairly sure that they work as normal lenses, refracting the light that enters them, but I would like some definite clarification of this. Poromenos 23:36, 4 October 2005 (UTC)
Cleanup"The first cosmetic contact was designed by optometrist named frankie for the price of about $5000 to a playboy model for a halloween photo shoot. (please fill in the name of this woman and date, its the photo of her wrapped with a snake)" This article looks like it needs some cleanup....Jackk 00:48, 4 December 2005 (UTC) Why remove Bandage lens section?I feel this is an important treatment for large corneal erosion or abrasions. It not only improves patient comfort, but helps the epithelium heal in an organized manner. I think this is a legit section, though could be rewritten. Comments? --Natebw 17:55, 1 January 2006 (UTC)

Some short term plans for this articleI have added various bits of information to this article in recent days. I would like to continue and I propose the following sections: Replacement frequencies (new section discussing one day vs. weekly vs. monthly etc lens replacement) Lens designs (spherical, toric, bifocal, monovision, orthokeratology). This would incorporate some of the existing sphere vs. toric section. Wearing modalities (daily wear vs. extended wear). This would use some of the detail from the existing section. Lens care systems, using some of the existing material. Adverse events with contact lenses. I would appreciate any thoughts on the above. Cheers. (Wiki-p 00:31, 2 January 2006 (UTC))
One question: Is it appropriate to single out Acuevue? If brands are to be added, at the very least Ciba and Cooper should be included as they worn by many patients. --Natebw 01:20, 2 January 2006 (UTC) PicturesWould there be any objection to adding another picture showing what contact lenses actually look like? I'm thinking of this one. Joyous | Talk 16:09, 15 January 2006 (UTC)
PerspexMany people are unfamiliar with "Perspex" and only know PMMA as "Plexiglas." Both are trademarks, but since the neutral term "PMMA" would also be unfamiliar to most people, I changed the mention of it to "Perspex/Plexiglas." The link is unchanged, since Perspex anyway. Using both names (at least on the first mention of the substance) makes it clear to all, and lets the article stand on its own. Even if you were to click over to "Perspex," the article in its current state doesn't mention other trade names for PMMA. You'd have to go to its talk page to find out. So there's my convoluted rationale for a very simple edit. Ckamaeleon 04:07, 20 January 2006 (UTC) ]
Lens TypesIsn't there a type of lens that one wears overnight to reshape the cornea. It's removed in the morning and your vision is improved or restored. After about 3 days it degrades again. I heard abotu it as an alternative to corrective surgeryt and don't see why they shouldn't be included in the article.Ckamaeleon 10:11, 20 January 2006 (UTC) I re-wrote some of 'spherical v toric', what was written would make no sense to a non-specialist. This article needs lots of expansion.--CorvetteZ51 09:16, 31 January 2006 (UTC) Request for peer review on KeratoconusA peer review request has been made for Keratoconus. If anyone would like to contribute to that, it would be very welcome. BillC 22:34, 5 February 2006 (UTC) Article removed from Wikipedia:Good articlesThis article was formerly listed as a good article, but was removed from the listing because there is a cleanup tag on the article. Worldtraveller 21:17, 25 February 2006 (UTC) ]
To Do ListPerhaps it was inappropriate to put so many things on the to do list and not discuss them on the talk page first. If that is the case, feel free to (re)move any items. That being said, I am excited about this project and am determined to make this page top notch. I especially want to cover the factors that go into prescribing contacts as well as proper contact hygein and complications that may result from poor compliance. With so many people wearing contacts, I see this as a public health issue. Natebw 03:19, 27 February 2006 (UTC)
History sectionWho was the California optician who refined the plastic lens? Does anyone have a reference for this? Also, much of the info in the "Rigid vs. soft contact lenses" section can be moved to the "History" section. Rewster 06:05, 27 February 2006 (UTC) Usage expansion ideawrt to usage, there appears to be no mention of why people chose contact lens over glasses. Two reasons come to mind for me
Other possible usage topics - can you swim in them? [2] says no, unles they are scleral. Same source also mentions that air conditioning in offices/airplanes drys them out. Just some ideas to throw into the mix as my prose writing isn't up to much! :) MartinRe 14:10, 27 February 2006 (UTC) Use in amusement parks?They can also be used in movies and amusement parks (though rarely outside of these fictional settings) to make the iris appear unnatural in appearence. Is there something I'm missing? When are cosmetic lenses widely used in amusement parks? Joyous | Talk 00:46, 28 February 2006 (UTC) Scleral lensesSome contact lenses cover the white (or sclera) of the eye; these are referred to as scleral lenses. Gas Permeable PhotoCan anyone find a good photo of gas permeable contact lenses? I tried to take some at the office this morning, but I do not have a good camera for shooting small objects. I will try again and upload the photos to Commons for consideration. Natebw 16:00, 28 February 2006 (UTC)
disposible section"Single use lenses are also useful for people who use contacts infrequently." Doesn't sound quite right to me, I'm trying to express that people who were glasses as well as contants would find daily disposibles better, as they would used them as required, but if you have monthly disposible and only wear them once or twice that month, you still have to throw them away. MartinRe 23:28, 28 February 2006 (UTC)
New headings under 'types'I found the heading names under Types of contact lenses to be a little confusing, so I took the liberty of renaming them. I'm new around this article, so if anyone disagrees, please just revert me and I won't be offended. BillC 00:20, 1 March 2006 (UTC)
Ionutcontact lensesDuplicate informationMuch of the information in the History section (1) is repeated in the Constructional Material section (3.2). As I read the article, I got to 3.2 and thought I was reading the article again, the content is so similar. These should either be merged together, or the appropriate information for each section isolated to just one or the other. Dansiman 05:23, 4 March 2006 (UTC)
"true" contactsIt was said on this page that August Muller made the first "true" contacts. I changed that to "more convenient" - but I was wondering what someone meant by "true" contact lenses - and by all means if i was wrong to change it, change it back. But if you do, please explain what a "true" contact lens is. Fresheneesz 02:08, 6 March 2006 (UTC) Glasses or ContactsI got my first eye glass prescription a year ago and I am thinking about switching to contacts. Can u guys tell me more about them. Is there a downside to contacts versus glasses. Do contacts move with your eyeball or is there only a circular field in your vision where everything is clear?--12.221.139.214 05:39, 30 March 2006 (UTC) All soft contacts move somewhat when they are in your eyes, and this allows you to see out of the corner of your eyes clearly with contacts when for normal glasses that would just be a blur. Toric lenses (for astigmatism[sp?) are somewhat more rigid, and consequently if your uncorrected vision is good enough to make out it's top and bottom it's best to orient it correctly. (The lense will fix it's oriention within your eye with minor help (blinking and moving the eyes up/down/left/right)) Non-toric lenses generally have no "up". Note that this is in contrast to inside-out; in which the only way to fix is to take them out. Actualy if looking thru one eye with a contact if there were a portion of your vision clear and another part not; that would indicate a problem. (Torn contact lense; lense inside out; etc.) Joncnunn 18:53, 12 April 2006 (UTC) care sessionIt might also be a good idea to point out the need to throughly rinse off the soap before either inserting or removing the contacts. (It's very painful if some of the soap is still on your fingers.) Joncnunn 18:53, 12 April 2006 (UTC)

Hi,
My name is Rosa Trieu and I'm a graduate student at USC, helping Andrew Lih on a research project for Wikipedia. Would you mind granting me access to edit the contact lens page?
Thanks very much!
Regards, Rosa Rosatrieu (talk) 07:14, 31 January 2013 (UTC)
- Hi Rosa and welcome, to avoid getting disappointed before you edit I just wondered what is that you wish to change or add to this article? if you don't like to discuss in this talk page before actually editing I recommend you to edit less important pages and after a few days you will be auto-confirmed and will be able to edit this page. However, the preferred approach is that you discuss it here first. Kiatdd (talk) 09:53, 31 January 2013 (UTC)

Removed from article: Effects of long-term contact lens wear on the cornea, replaced with link to this article
General risks
In general, contact lens use is thought to be safe as long as the proper precautions are adhered to. The most prominent risks associated with long-term, chronic low oxygen to the cornea include increased epithelial permeability, bacterial adherence, microcysts, corneal edema, endothelial polymegathism and potential increase in myopia.[1] Mishandling of contact lenses can also cause corneal abrasions, which can progress to bacterial keratitis which can lead to corneal perforations, scarring, and vision impairment.[2] Furthermore, decreased corneal sensitivity following extended contact lens wear may increase a person’s susceptibility to becoming infected without being aware of it.[3]

Second “Usage” section
What is going on with the second “Usage” section in this article? It simply is a list of three external links with short descriptions. This seems like a mistake and may be a failed attempt to add citations to the first “Usage” section of this article, which actually has text content. Can somebody knowledgeable about the situation fix this? Thank you! — Nicolás Macri (talk) 07:47, 27 March 2022 (UTC)

Usage
Drying of hands using towels or tissues before handling contact lenses can transfer lint (fluff) to the hands and, subsequently, to the lenses, causing irritation upon insertion. Towels, unless freshly laundered on high temperature wash, are frequently contaminated with large quantities of bacteria and, as such, should be avoided when handling lenses.
So one should leave one's hands unwiped in the air until they dry by themselves? What if one's skin is already so dry that this process will make one shed flakes onto the lens? Is there no workaround? 195.187.108.130 (talk) 16:35, 14 June 2023 (UTC)
Bifocal and multifocal contact lenses
Needs a new section with a lot more on the options and how they work. 209.93.202.35 (talk) 10:53, 3 January 2024 (UTC)
