Jmaine (M/17) came for eye examination, vision with existing glasses of 3+years is fine seeing far & near. He notices that if he holds his phone upclose, vision would be blurry sometimes & he will then hold it further away & it’s fine. Having sinus, he tends to feel itchy eyes in which he may mildly rub his eyes sometimes.

L: -3.50/-1.25×5 (6/6-)
Examination shows:

When we tried to lower shortsightedness 025 in left eye binocularly, he did not like it
Other assessments show:
Examination of Eye Alignment/Vergence (Cover Test)
NMD @ Distance
NMD @ Near

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
Near: 0 – 2 XP (blue part)
+1.00 Near: 0 –> 2 –> 4 –> 2 <–> 0 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

Jmaine has different of 150 shortsightedness/myopia in both eyes.. same like father Mr Raymond who have different of 200 between two eyes too. He has some increment in his astigmatism now, otherwise his eye systems – accommodation & vergence look fine. We will update his power/refractive error & optimise his astigmatism.
Jmaine has sinus, when he was young, doctor told him that he has narrowed airway hence difficulty breathing through his nose. He will breathe through his mouth instead. But when he plays sports, he plays futsal.. he finds that breathing becomes easy through his nose during sports. That makes him into sports. Previously, he removed his glasses to play futsal.. and he has just started wearing contact lens to play futsal & he is loving it. Yes, contact lens is an option for sports purposes. Tell your eye care practitioner about your needs & lifestyle, we will be able to prescribe you with suitable optical correction.
Denying a clear vision while enjoying your sports…. you do not have to choose either one.. you can definitely have both & comfortably tasting life!
Mummy Sharon has also asked if Jmaine is suitable to drive, especially at night, considering his high astigmatism. Yes he can surely drive with his updated prescription.
Jmaine, you will be driving soon yo.. be safe & congratulations!? Aunty will check for your dry eye when you come back soon.
