Inversion therapy involves being upside down or at an inverted angle with the intention of therapeutic benefits. When the body's weight is suspended from the lower body, the pull of gravity may decompress the joints of the body below the anchor. People who have heart disease, high blood pressure and eye diseases are at higher risk for the dangers related to inversion therapy and should consult their doctors about it first. Although Manufacturers of inversion tables claim their products can help curb back pain and improve blood flow, it still exists high risks. The most important concern that you must take care is that inversion therapy can damage leads to an increase in intraocular pressure, a measurement of the fluid pressure inside your eye, which is easy to cause blurry vision and redness. Here are some other effects include excessive accumulation of fluid around the eye, red spots on the eyelids, excessive tears, and sub-conjunctival hemorrhage, or bleeding beneath the white part of the eye. Inversion therapy are really bad for your eyes.
In December of 2017, I used my inversion table for about three minutes. I already wear glasses and my diopter is about -3.75 in both eyes. After a few days I started to notice that me vision was becoming blurry in my left eye. I went to my optometrist and he said it wasn't correctable by lenses. What? I used glasses my whole life...I went to my Opthamologist and I told her about the inversion table...she didn't think it did anything...My prescription had changed in my left eye..the astigmatism had definitely gotten worse. New lenses were ordered and my vision was still not perfect. I kept my old glasses just in case. Three months later, I noticed that my new glasses were getting worse. I tried on my old glasses and they were actually better. I went back to my opthamologist and she said my eyes returned to my natural prescription. I believe that this table changed the shape of my eye temporarily from the pressure of being upside down. She agreed with me. My eyes felt like they were popping out of my head back then. This may not affect younger people but I caution older people to not use it. I was 66 years old at the time. I am selling this piece of crap for $75 this Friday. (to a younger guy)
According to the relative researches, it is unclear that what are the long term impacts of inversion therapy on eyes. But it is clear that these impacts do exist. In their study, they found that the intraocular pressure in eyes after inversion is more than doubled. The pressure in retina artery is increased too. You can find that the conjunctivia is red for the small hemorrhage. Anyway, if you have any eye problems like vein abnormality, glaucoma, macular degeneration, ocular hypertension or other disorders, you'd better not to take the inversion therapy. It might cause many other problems although it might be beneficial in different angel. Inversion might even cause a stroke for the blood bursting into neck and brain. It could be dangerous for some people, so I suggest you to consult a doctor before you take it as therapy.
