Power of existing glasses 1+ yrs
R: +0.50/-0.75×80
L: +0.50/-0.75×80

Examination shows:
R: +0.75/-0.75×80 (6/6) [+1.00 blur lens test 6/9-)

Other assessments show:
Examination of Eye Alignment/Vergence (Cover Test)
NMD @ Distance
small XP, fast recovery @ Near
(normal value: orthophoria/NMD-No Movement Detected or small XP, fast recovery)
EP = Esophoria is misalignment of the eye, eye is deviated inwards
XP = Exophoria is misalignment of the eye, eye is deviated outwards
Examination of Eye Alignment/Posture (Howell Card) by 6^ Base Down on Right eye
Distance: 0 – 2 XP (blue part)
Near: 8 – 10 XP (blue part)
(normal value: 0-1 EP or 0-3 XP @Distance and 0-6 XP @Near)
EP = Esophoria is misalignment of the eye, eye is deviated inwards
XP = Exophoria is misalignment of the eye, eye is deviated outwards
Cindy has longsightedness/hyperopia with astigmatism in both eyes. Her daytime driving is fine, as bright light makes our eye pupil small which in turn activates our eyes’ focusing & facilitates in autocorrecting the power. Pupil is big during night driving.. (aiyo we cannot use autocorrect mode at night lo.. so vision is blurry).. with more light passing through our big pupil (more scattered light in eyes with astigmatism) hence complaint of glaring.
Our eyes also tend to be tired during end of the day.. no energy left to do autocorrect already. Normally, you find that your vision gets better after a good rest. Like Cindy, she can see pretty good without glasses.. but she reported having tired eyes easily.
By correcting your longsightedness/hyperopia is all you need to do to revive the freshness they once had.. the “ai xiao de yan jing” – the sparkly, smiling eyes!
Wearing glasses no old lah.. it simply means we love our eyes as much as we love & be proud of our eyes & ourselves!
We are so sorry that we cannot deliver her multifocal glasses face to face due to our quarantine. Initially, we asked to have a video call so that we can explain to her. But, we ended up sending a recorded clip over to her to explain the way to use her multifocal glasses. It is applicable to all multifocal users too. We will see her to explain again soon.
Cindy, wo xia ge li bai bang ni adjust yan jing a?
