EP = Esophoria is misalignment of the eye, eye is deviated inwards
XP = Exophoria is misalignment of the eye, eye is deviated outwards

Uncle Yap has some astigmatism in both eyes. So, readymade reading glasses will not be suitable for him. His vision is pretty good with mild cataract in both eyes. He has quite significant pterygium in right eye though. Both cataract & pterygium develop from exposure to UV or the sun. Both conditions are in need of treatment & management from an eye doctor/ophthalmologist. We will monitor & refer you accordingly.

Uncle Yap, grab helmet & grab sunglasses also before you go ride your motorbike!
