My tDCS Story: A Six Month Retrospective — tDCS Global — Medium

After six month of tDCS focused on my optic nerve and visual cortex combined with visual training, I have had marked improvements to my visual perception, especially in contrast perception and perceiving objects from afar. For example, if I am walking on the sidewalk, and another person is walking in the opposite direction towards me, I would not have been able to notice the other person until they were about 1 meter away. Now, I will notice people from 3 meters away. I can’t see them clearly enough to identify them, but at least I can move out of their way, if they’re in a hurry. Likewise, I can see oncoming traffic from 2–3 times farther away than before, which is very helpful when crossing busy streets. Another example is when I use my computer. I use a large Apple 30” display, and before starting tDCS, I would sit with the monitor about 3 inches from my eyes. As you can imagine, this was not at all comfortable, but I had to do this in order to see the screen clearly. After the first few days of using tDCS, I was able to push my monitor back and sit 6 inches away from it. Within two weeks, I was sitting about 12 inches away. Now, I sit 18 inches away. This is the first time in my life I’ve used a computer at this distance. Similarly, I’m able to use my iPhone at much greater distances than before 6 inches now, compared to 2 inches previously.
