Hi!
Based on your prescription, 1.6 index would be best. It would cost you
1.6 index sync 3 pro(free upgrade) 390 w/full control(blue light filter) 70, total damage will be 460 before discount.
You could go down to
Jamco optical@katong shopping center
Eyewear optics@thomson plaza
First eyewear@East coast or @far east plaza.
It’s best to make an appt before going down and if needed, I can pm you who to look for.
Thanks Gangsterkia for the details.
I'll update you over the weekend
