Pressure increased. I hope its not that.

Few days ago i noticed that i was unable to read light boards during night. It goes dizzy when i try to read them. I ignored. I thought this might be due to tiredness. But then i started feeling something strange in my right eye. I noticed a difference between the vision of left and eight eye. And also when i sit in front of computer screen and mobile, my eyes get tired after few mins. Finally yesterday i got myself checked. They examined my eye sight which is nornal and eye pressure (IOP) through maching and manually too. Machine detected 24mmhg. Doctor gave me anesthesia and checked. He wrote Corrected IOP on my report. That is 25mmhg & 24mmhg. He precribed me some medicine and asked me to visit after 10 days. I am very afraid. Only yesterday i heard about glaucoma. I hope its not that.
