Mr Teoh (M/49) our customer friend, Racheal’s husband came for eye examination, with complaint of headache around head for 1+ year. He wears a pair of reading glasses only. He has sinus since 30 years ago.. he recently got warded for treatment on his sinus.

We prescribe a separate pair of glasses for far vision for full-time wear to let his eyes slowly accepting the hyperopic power/long-sightedness. His finding of divergent fusional reserve, NFV @distance tells us that: when his eye can accept higher hyperopic power, it boosts his NFV.

Mr Teoh, father of HYin came back & reported that he cannot see dashboard wearing single vision glasses for far vision.
We are not sure whether or not his headache is due to sinus or otherwise.. but we can try to optimise his vision & we see how it goes. We prescribe multifocal and we will see him after 2months of full-time wear of multifocal glasses.
Glad to hear that he finds warm compression & lid massage work for him in alleviating dry, burning sensation due to oil gland blockage. When he feels the same dry, burning sensation coming back, he will then repeat to do warm compression again.
