I'm currently still in Thailand but not in Chiang Mai anymore, I am currently staying in Bangkok, before I went on my trip I actually had red eyes or pink eyes for 2 days so it was really watery and serious but it actually become better after I reached Thailand.
But what I didn't know was that even though the redness wasn't there but my right eyes vision just keep getting worst and worst until I can't see clearly anymore even though the person or thing was right in front of me which lead to me falling down on the first day I arrived in Chiang Mai.
So I started to get panicking and worried on the following day so I told my parent about the situation and they decided to fly me over to Bangkok and visited their international hospital : " Bumrungrad International" to see the eye-specialist.
I nearly cried when I was doing the eye test because I realised I can't see anything at all, the hospital conducted the eye pressure text, vision tests and a lot of other tests. The doctor told me that inside my upper eyelid, it grew a lot of white bumps (due to the facts that I actually wore contact lens for long hours) which lead scratches on my corneal so it lead to corneal abrasion (also known as corneal scarring) and the corneal become cloudy to protect itself so if I didn't get to the doctor in time I might actually turn blind in a day or two.
I was so damn scared hearing that, luckily my family was there for me during this hard time. So the doctor prescribed me non-preservative eye drops which I had to use every 1 hour in order for me to see clearly and I can't wear contact lens anymore.
So yeah, that's what actually happened. For all you guys wearing contact lens out there, please be careful and see doctor if you feel discomfort or when you sense there's any unusual feeling in your eyes. Don't delay visiting the doctor because it might actually cost your sight forever.
