hi, get those with high oxygen then you may wear them longer hours. silicone hydrogel lens allow you to wear them more than 12 hours safely during open eyes time, not when you sleep.

My friend uses monthly extended wear lenses, but he actually only takes them out to change once a month!!

He says he feels perfectly comfortable, been doing that for years...

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.

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

Just look for any optometrist shop will do.

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.
