Onlangs het ek op die radio gesels en een van die aanbieders het my gevra wat ek die meeste geniet om in die praktyk te doen – EN ek het soos volg geantwoord:
“Ek hou daarvan om moeilike oë te toets”… 😂

SO, ’n paar dae later sit ’n pasiënt in my stoel en sê vir my - Sy het na my radio-onderhoud geluister en sy het net een vraag wat sy vir my wil vra…

“HOE weet ek… 😳… as ’n pasiënt – WANNEER ek moeilike oë het… 😳😂”

Sy het my letterlik met dié eenvoudige vraag, uit die park uit geslaan...en my laat kopkrap, selfs oor Kersfees en Nuwejaar!

SO - WAT is " MOEILIKE oë" as pasiënt..

Color blindness is not gender blind. In fact it is much more common among men. It affects 1 in every 12 males in this country but less than 1 in every 200 females.
Facebook is blue because its founder, Mark Zuckerberg, suffers from red-green color blindness.
In true color blindness facts, people are “color blind” only if they see just black and gray. This is actually very rare. The more common condition is “color vision deficiency,” where greens and reds can look confusing.

There are several interesting color blindness facts. Like, did you know Facebook is blue because Mark Zuckerburg is color blind? know color blind facts!
