Red Eyes for 3 weeks now? Should I see a Doctor?

Hi, so I'm 17 and I have been getting red eyes for 3 weeks now, It started with my right eye. My right eye would get super red and my left eye would get a little red.
So I went to the pharmacy and got Clear Eyes Red Eyes Drops.
I tried putting 2 drops each day and it would remove the redness but when I wake up, it will get really red.
So few days ago, I went to get another brand of red eye drops, called Optrex.
And it doesn't really work as well as my old eyedrops.

So yesterday because it was orientationday at school, i got fruesyrated and put 4 drops thoughout the day of BOTH of them?
It ia probably bad to mix them?

So now when I woke up my eye are super red and theyfeel kinda weird?

I've been thinking that its due to eyestrain from watching too much TV, and looking at my iPhone? But I've been taking breaks in between now? And it still doesn't get better? Maybe the the eye drops made it worse? My eyes started to sting a little.

You should not continually use any of that red eye stuff. It clearly says on the box not to use for extended period of time or it can be harmfull. The only thing you should use continually in the eyes is the artificial tears, and even with those make sure it says preservative free if using daily as those will help lubricate your eyes which may help alot. Most get dry eyes from staring at screens.
If your eyes are really red, then yes I would go see an opth.
