Closed-eye visual hallucinations after coronary artery bypass grafting. You can learn more about how we ensure our content is accurate and current by reading our editorial policy. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. The temporal lobes also control short-term memory. Researchers hypothesized that the hallucinations may be related to temporal lobe epilepsy, which causes seizures in the emotion-regulating parts of the brain. While hallucinations aren’t listed as a common side effect of lidocaine, other related side effects of topical applications of this medication include:Īnother study on heart surgery patients noted closed-eye hallucinations as rare side effects after this procedure. The ingredient is also sold in some over-the-counter topical numbing agents used for muscle aches and joint pain. This is a numbing agent that may be used in minor surgeries and dental procedures. Researchers concluded that this case was caused by a reaction to lidocaine. These closed-eye hallucinations were followed by racing thoughts for two hours. After surgery, the patient reportedly experienced hallucinations whenever he closed his eyes over a four-hour period. ![]() One such study found closed-eye hallucinations in a man who had minor outpatient surgery with local anesthesia. Other closed-eye hallucinations have also been reported in some people after they have surgery. It’s estimated that hallucinations occur in about 0.5 percent of people with sodium levels of less than 120 mEq/L, but the exact number of closed-eye hallucinations is not known. This condition causes extremely low blood sodium levels of 135 mEq/L or less. Other causes of closed-eye hallucinations may be related to medical conditions, including the following: HyponatremiaĬlosed-eye hallucinations have also been clinically observed as a secondary condition in people with hyponatremia. There may also be an increased likelihood of seeing more colors when light pressure, such as a blindfold or sleep mask, is placed against your closed eyelids. If you close your eyes in a lit-up room or outside in the sunlight, chances are that small amounts of light could create a visual effect. At rest, your retina still continues to produce these electrical charges. These occur as a result of the constant activity between neurons in the brain and your vision.Įven when your eyes are closed, you can experience phosphenes. I just saw a thread about it.What typically causes closed eye hallucinations?Ĭlosed-eye hallucinations are related to a scientific process called phosphenes. If you want lab-like results or better, then use a proper C41 chemistry that labs use: Flexicolor from Kodak or Fuji's Negacolor. They are sort of like chemical equivalent of Lomo's quirky color films, for folks who want the "film look". I do not view these kits as a fit for those who care about image quality. When I tried this kit, I managed to wrestle the colors post-scanning, but it took a lot of effort and the contrast was always too high (probably because blix leaves some silver in the emulsion). In other words, it's kind of pointless to troubleshoot when you're starting with a bunch of compromised fundamentals. ![]() To recap what Cinestill sells: the fixer and bleach are mixed together, chemistry capacity is overstated and the temperature recommendation is too high. The temperature is also supposed to be 100F, and not 102F. BTW Kodak, who invented the C41 process, claims that 1L of a developer is good only for 4 rolls. You can't expect perfect results from a blix-based kit. Trying to be helpful: try to lower the temperature.īut to be honest.
