Just go to Thoneh if you are around KL. I dont trust optometrist already.
Last time I went to one cause got free check, turns out my right eye power is 150 or something that i need glasses.
Next day went to Thoneh cause paranoid and want 2nd opinion. There they say my eyes power on 75 or something, basically its too low to start using glasses.
