Examination of eye alignment (by Howell Card)
Far vision
Latest pair : 0-2XP
Previous pair : 0-2XP
Oldest pair : 0-2XP
Near vision
Latest pair : 10-12XP
Previous pair : 6XP
Oldest pair : 6XP
XP = Exophoria is misalignment of the eye. When the magnitude of misalignment is within 6, it is normal.
For Mr Chok’s latest pair, he has 10-12XP when seeing near. This may be causing him to have headache.
We have advised him to stop wearing his latest pair of glasses & only wear his previous pair of glasses and sees if his headache subsides. He is to come back for follow up in 1-2 weeks.
