Eye Care & Problems

I constantly feel itching in eyes, while I am using my laptop or phone. I use laptop and phone approx 12 hours daily

I'm getting head ache while reading books. I have little eyesight issues but they are negligible. Any home remedies to prevent head ache and illusions would be suggestible and what I'm looking for. Thanks in advance!

1. Can acquired squint be corrected only by eye exercise? (15° exotropia, but fusion remains 80% of the day) 2. Is squint a problem of eye muscle weakness or of brain nerve weakness? 3. Already operated for squint 18 years ago now what is the guarantee that eye do not drift again in future if I go for surgery again? Aren't squint suegries successful in India? 4. Doctor said to operate on my left eye to correct the squint in right eye because right eye muscle was already cut during my first surgery. Is it possible to correct squint like this? I am scared if my left eye also get squint after surgery. PS. My vision is 6/6 in both eyes without any glasses.

My eyes are blurring when I go to out side in day time, after rising my eyes towards up & down. I am using speticles the problem is low if not it is high. Can you suggest me best medicine. Now I am taking medicine for Diabetic.

If I have spectacle power of  sph  -3.75 ; cylindrical 0 , what will be the contact lens power for the same? Attached is the prescription of the same. Also would like to know what is meant by vision column and how can I make sure that I am getting the correct powered contact lens?

My eye sight is very week. In the morning my eyes are fine but at the end of the day i feel irritation in my eyes and the become water. Also i feel like a layer of some very slightly, but some sticky substance has covered my eyes, lowering my vision even more. I also see black substance floating around my eyes sometimes.

My eye is totally allergy free and i have no vision problem...but my lower eyelids are puffy ..how to get rid of this?
