All contents on this site should be considered research material only.  We are not offering medical advice or treatment or cures for any illnesses. Before considering taking steps to control your own myopia, you should definitely visit a qualified ophthalmologist for a comprehensive eyesight checkup.   Specific diagnoses illnesses aside,  most) myopia may be considered to not be an illness at all.  Most myopia is likely just a matter of environmental strain, and excessive prescription use.  You yourself may be able to control and reduce your own myopia by 1) managing eye strain, 2) conservative prescription lens use, and 3) targeted positive stimulus. We recommend finding a prevention minded optometrist to supplement your journey with professional advice and prescription management help.  While not a requisite, a supportive optometrist may make your journey that much more enjoyable! Potential Side Effects: (1) You may experience astigmatism-like symptoms, especially if you reduce too fast or without paying attention to this (transient) symptom. Search our Youtube channel or Website for 'transient astigmatism'. This can easily be prevented or managed. (2) Some people report an increase in eye floaters when practicing active focus. In general floaters are considered harmless but a sudden increase in floaters should be evaluated by a medical trained professional, as they could be a sign of retinal detachment or other serious medical condition. Generally taking it easy, not over straining, practicing gently and with patience should help. (3) Headaches. You're taking on a very much unsanctioned self-experiment changing diopters. Anytime you overdo things or change too much or aren't educating yourself first, you may expose yourself to strain symptoms. You should be experiencing no pain, headaches, or discomfort if you do things correctly!
