if monthly lens, you can consider biofinity

if biweekly lens, acuvue oasys is good.

dailies lens are expensive and good for those only use lens once or twice a week, can consider oasys dailies.

He's using Air Optix monthly disposable multifocal.

He tells me taking the lenses out to wash has a higher risk of infection...

The monthly or biweekly lenses have to wash in the solution right?

FDA only approved for 7 day 6 night max for extended wear without removing from eyes, but I strongly recommend not to do that.

Yes all contact lenses must wash with soft lens solution even dailies one, before putting them on your eyes.

Any spectacle shop can do contact lenses for me, or are there things to take note of?

Just look for any optometrist shop will do.

Do you have your own shop?

I go to my regular optometrist shop in taipan subang jaya, take contact lens stock from them also.

you can go to your house nearby optometrist shop to check.

Can recommend the optometrist shop that u go to please? I stay near taipan usj10 there too
