 Item Number, SCP-558, Object Class, Safe Special Containment Procedures All items comprising SCP-558 are to be kept in their cases in equipment cabinet at research site. Any personnel wishing to experiment with SCP-558-14 may do so after completing standard documentation. Researchers wishing to test SCP-558-5 must either themselves have level 3 clearance or have the written approval of at least 2 level 3 personnel. At this time, it is advised that only Class D personnel be allowed to interact with SCP-558-5. Description SCP-558 includes a number of different types of colored contact lenses divided by researchers into 5 categories by apparent properties. Currently, there are 10 of each contact lens in categories 1 through 4 and 6 contact lenses of group 5. Whereas normal contact lenses are fitted to a particular wearer's eye shape by diameter and curvature, each individual lens in SCP-558 seems to be able to conform to any eye shape. Testing is currently underway to determine the composition of the material without damaging the lenses. In their resting state, they have been observed to have a 10mm diameter and 8.7mm base curve radius. Subjects using the lenses with prescriptions requiring different dimensions reported initial discomfort, then a tingling feeling as the lenses adjusted to the shape of their eyes. Rather than standard clear, each lens has a colored central portion slightly wider than the average human iris. The colors are red, violet, green, gray, and black. These colors seem to correspond to distinct properties, though all lenses appear to correct vision to 2020, regardless of subject's actual vision quality. How this occurs is currently unknown, though testing is ongoing. SCP-558 was found in a toiletries case in the bathroom of room of the Red Hotel during a raid called in to investigate reports of data expunged. The saline solution found accompanying SCP-558 was determined to be normal, so any standard solution may be used. No other extraordinary items were found in the bathroom. SCP-558-1 includes 10 red contact lenses. Testing with these lenses met with initial difficulty, as subjects immediately complained of blinding light, even when they closed their eyes. Repeated testing in different locations finally revealed that these lenses allow a wearer to visually perceive electromagnetic emissions of a longer wavelength than visual light. Since the Earth is usually blanketed with radio wave communication, which passes through flash eyelids, these most often display blinding amounts of light. In shielded underground facilities, however, it is easier to manage. Provided inter-facility radio communication is restricted. Subjects reported seeing infrared radiation in a way similar to night vision goggles, though the color scene was not exactly red. Test subjects have had great difficulty in expressing the color scene, but they are adamant that the lenses do not simply convert light or red, but actually show a distinctly new color. They simply lack the language to describe it properly. SCP-558-2 includes 10 violet contact lenses. Testing with Group 2 was more successful than 1, as initial tests took place inside. However, when test subjects were allowed to view outside, daylight was significantly brighter than normal, and several personnel had their vision permanently damaged due to sudden exposure. Tests indicate that these lenses, inverse to the red lenses, allow wearers to perceive wavelengths shorter than visual light. The addition of the ultraviolet radiation from the sun to already intense visible light means that direct sunlight is simply too intense to view comfortably. Test subjects were also able to see X-rays coming from a nearby medical examination room. Testing with gamma rays is being planned, though researchers are unsure if they might harm SCP-558-2. SCP-558-3 includes 10 green contact lenses. Testing with the lenses of Group 3 revealed that rather than allowing a wearer to perceive wavelengths previously invisible, the green lenses enhanced the colors of the visible spectrum to a high degree. Test subjects reported an unparalleled vividness of color and clarity in normally dull objects. A class D personnel with a history of drug use reported a similar experience to the use of some hallucinogens, though much more consistent and vivid. So far, the only adverse effects observed have been headaches and eye strain after looking at particularly colorful images and objects. SCP-558-4 includes 10 gray contact lenses. Subjects wearing lenses from Group 4 report being able to see only in gray scale. However, it was quickly noticed that somehow, subjects' field of vision had been expanded. While normal humans have 140 degrees field of binocular vision, with 40 degrees of peripheral vision, 20 degrees each on the right and left, testing indicated subjects' binocular vision covered 210 degrees, while their peripheral vision covered an additional 60 degrees, 30 degrees each on the right and left. Test subjects experienced severe vertigo when moving for approximately the first 30 minutes of wearing SCP-558-4. After adjusting, subjects were able to move around without difficulty and were pleased by the greater visibility, though most complained of headaches. Subjects also reported that their distance vision seemed sharper, even though subjects who had possessed 20-20 vision naturally. When Professor W. W. theorized their increased field of vision is due in some way to a bending of perspective, researchers asked test subjects to attempt to focus on an open doorway. Approximately one in three subjects was able to bend their vision around a corner and see a brief glimpse into the hallway. All subjects attempting this, even those who failed, experienced mild to severe migraines immediately afterward. Further testing to understand and to take advantage of SCP-558-4 is ongoing. SCP-558-5 includes six black contact lenses. Currently, only Class D personnel should be allowed to test SCP-558-5. When testing these lenses, approximately three in five subjects immediately lost consciousness. Those remaining conscious immediately shut their eyes and began to shake violently, demanding the contacts be removed. Several subjects harmed themselves and the lenses trying to remove them, resulting in the loss of four lenses and a number of Class D personnel. When subjects were restrained and forced to open their eyes, all immediately degenerated into sobbing and incoherent babbling. Most subjects black out shortly after this point. To date, two subjects have remained conscious and open-eyed with SCP-558-5 in their eyes. The first, Class D personnel D-755-322, stared blankly straight ahead and seemed unresponsive to stimuli, even pain. She was observed to mutter continually, but no words were discerned. After the lenses were removed, D-755-322 went into a catatonic state in which she remains in the medical wing of research site. An interview with the second, Class D personnel D-344-219, is appended as document SCP-558-5A. It is theorized by Professor Scully and Dr. W. W. W. W. W. based on the interview that the SCP-558-5 lenses somehow allow subjects to perceive time, often called the fourth dimension, in a visual way. It seems that the average psyche is not capable of handling the increased perspective and in most cases, the mind turns inward, causing unconsciousness and memory loss consistent with disassociative amnesia. Experimentation is ongoing in an effort to further understand SCP-558-5, specifically if they enable the wearer to see points in time other than the present. Researchers are hopeful, given that testing has revealed the wearer's ability to control the effects of SCP-558-4. Priority is given to testing involving possibilities of precognition. Addendum During routine evaluations, approximately three and four persons who had worn SCP-558-5 had exhibited signs of severe depression and anxiety. Moreover, one in three had incidents of self-mutilation, usually of the eyes, often accompanied by suicidal tendencies. Document SCP-558-5A Begin transcript. Skip to four minutes twelve seconds. Doctor, I'm going to ask again. What did you see? D344-219 Incoherent Doctor, what was that? D344-219 Mumbling Web Doctor Web Elaborate, please. D344-219 It's a web. Doctor, what is a web? D344-219 It's damn sure not a line. And it's not a circle either. It's a f***ing infinite web. Doctor, are you referring to what you saw? You were able to see a web. D344-219 Look, why don't you put the damn things in? Then you'll understand. Then you'll know. Incoherent Doctor, where was this web? D344-219 Subject begins to shake. Everywhere. Doctor, what do you think it was? D344-219 It was you! It was me! It was everyone in the world! All connected, branching out. Who they were, who they will be. And the death of everything was there. The end. Dark. They let me see the edges all the way. So dark. Subject begins to weep. Doctor, I don't understand. D344-219 Sobbing. Pray to God. Let you never do. Subject begins to hyperventilate. Sedated. End transcript. Lesson complete. If you missed the previous orientation, go watch SCP-557, Ancient Containment Site, right now. Or for the complete course, watch this playlist.
