I have worn Daily Disposable lenses for a couple of months and could wear them the whole of my waking day without any serious discomfort or having to use eye drops, etc. But most of my life I wore yearly Soft Lenses and have recently been wearing Biofinity lenses.

Having said that, at present Daily Disposable lenses tend to be made of the standard hydrogel material, which is less (oxygen) breathable than the latest generation Silicone Hydrogel lenses. So, wearing standard Daily Lenses for 14-18 hours/day (as I may have done on occasions) is usually not a good idea in regard to oxygen flow to the eyes.

You need to be guided by your Eye Care Professional, who will check to see if you have any increase in the capillaries growing into the whites of your eye (neovascularisation). If this is increasing, then you would need to reduce the contact lens wearing time or switch to a silicone hydrogel lens with better oxygen permeability.

I expect that in time, silicone hydrogel materials will become readily available in many Daily Disposable lenses.
