How fast do they eyes heal themselves from?!

In most cases eyes/vision heals or recovers pretty quickly. Excessive use of computers and TV watching can cause temporary eye restrain and the condition should resolve fairly quickly once you resolve the cause, give your eyes a break from the screens as often as you can. If you used the wrong over the counter eye drops, once you've stopped using them, any problems should resolve. Using the wrong prescription eye drops could certainly cause sight threatening problems so you should stop using them immediately and you ought to see an eye specialist, if the Rx drops have caused vision problems. Coconut Oil and soap will not effect your eyes for any length, but washing your eyes with clear water is advisable.

Now, if the non-prescription contacts are the ones sold illegally online or at malls because they are not legal in most Western countries, you could have big problem. These costume, circle, geo lenses can block necessary oxygen from reaching the eye causing sight threatening infection and have also been known to slice through the wearer's cornea.

You are suggesting you did all of these things to your eyes?

I suggest if you have myopia issues to relax about the "prolonged" use of computer screens. If you're not relaxed and forcing yoruself to sit in front of a screen and you stare at it then yes thats bad. But using near vision is a requirement in keeping the ciliary muscle in top shape. Like any muscle it needs to be engaged or "exercised" once in a while for it to keep working. So the nearness of the object or screen youre looking at is not the issue. Feeling uncomfortable and stressed in your predicament would lead to serious issues in the long run.

Talking frankly most people naturally get bored when looking at something close up for too long and reach a point where they will look elsewhere. Dont try to count out the seconds of the period that youre looking at your screen. This kind of behaviour indicates that you're way too tense and ruining your day with this strange approach to life.

I dont understand why you use eye drops, coconut oil and soap in your eyes. Really if your eyes are normal why are you bothering with all that?

Non-prescription contacts as in contact lenses that change the colour of the eye? well if you notice a change in your vision or some redness in your eyes then just stop using them. No harm in using your eyes normally.
