Before this app my professor and I thought I was a zombie.

Consmc31 on

My brain seems to be looking at things better now and my eyes feel like the computer vision syndrone eye strain I suffered from decreased significantly. I feel more stable now that I don't feel so stressed and dizzy. It's pretty expensive for just playing a pattern. And you'd be outright crazy to not pay $3.99 to see these changes. Also, the eye strain of having hella bad tunnel vision caused by the iphone was causing my dry eye because it's reversed with this app. They should make this technology have more peer reviewed double blind studies and also make it more well known that cybersickness and feeling like the phone is making you sick doesn't mean you are crazy it may just mean you need these exercises the help with something not natural like looking at a smartphone. Even my family members said they felt better using the app a few times. I feel like the smartphone made me feel like a zombie before and just feel a lot less tense and more relaxed. Look up the National Geographic article on cybersickness and you will start to see what some people suffer from with these smartphones being so prevalent.

Don’t want to keep paying for this and can’t figure out how to uninstall

Dont want this app

Want horizontal stripes

megletr on

Mine will only display vertical stripes and I need horizontal as well as vertical for mdds symptoms. I am not sure if that is possible with this app. If so, I don’t know how to do it

This works quite well. Tap the screen to make the strips go faster. Level 1 through 5. I’m using this app to treat my nerve/ muscle paralysis in my left eye. It was recommended by my therapist. This exercise and time and hope.

Good app

SpaceSnaxxx on

Red-Black inversion doesn't work on grid test but otherwise a good app. You can get back to main menu from optokinetic by holding down on screen for two seconds and the back menu appears.

Good
