What is the difference between monthly and daily lenses?  They are sold
at vastly different prices (Online discount prices Ciba £5monthly/60p
daily; J&J £5/93p) but logic suggests manufacturing and packaging
costs are the same for both and the lens itself must cost almost
nothing.

Ciba dailies certainly feel a lot thinner than monthlies and i have
trouble with them drying out and falling out sometimes.  The J&J
SureVues feel the same whether monthly or daily.

It strikes me that this is probably completely marketing lead and using
dailies for a week at a time with 'all-in-one' cleaning fluid would be
healthier and cheaper than monthlies if they're basically the same lens
with the added bonus of lower replacement costs when a lens was lost.

stick with whatever is more comfortable. If you like glasses, wear
those instead. Dont overwear contacts and dont sleep in them or youll
ruin your eyes

I find glasses weigh on my nose by the end of the day, get dirty and
are no use for cycling so prefer contacts but try to wear glasses at
least one day each week.   I sleep in lenses overnight only if i forget
to take them out (maybe once or twice a year) and I rarely have any
problems with comfort  wearing them from the time i get up to the time
i go to bed but find the cheap Ciba dailies more problematic in terms
of drying out than the monthlies.

Do you have any views on what i actually asked?

Some companies make similar lenses that they sell at different price
points for daily, bi-weekly, or monthly replacement.  But CIBA Dailies
is a unique material, specifically designed for daily replacement, and
you should find that the lens will not hold up well to multiple days of
wear.

If they are drying out and falling out, why would you want to wear them
anyway?  Get a lens that lets you feel great and see well.

Because they're nearly half the price of Surevue dailies! However, I
was wearing the first of a batch of Surevue daily moist over the
weekend in very dry dusty conditions and they were really comfortable.
it's those i'm thinking of wearing for a few days to bring them down to
the price of the Cibas.
