Hi! That depends on your own eye sensitivity, which can be very variable from one person to another and even from day to day. In general the recommended wear time is 8 hours or less. Definitely make sure to pay attention to how you feel and what your eyes tell you, that's still the best way to tell ! :)
(On another note, can confirm that Olens lenses look very natural and flattering, even on dark eyes!)

The duration that you can wear one day contact lenses without experiencing eye irritation can vary depending on several factors such as your eye sensitivity.
Although it's generally recommended to wear them between 8 to 12 hours per day, it's better to use for less than 8 hrs.
Avoid wearing lenses for longer than recommended because this can increase the chances of eye irritation.

Hi :) I wear daily lenses nearly everyday and find that Olens lenses are less drying than my usual lenses from the optician! I can wear them for 9-10 hours and they will still feel comfortable, I suggest using eyedrops if you want to wear them for more than 10 hours!

Hi! montly lenses, try to wear them up to 7-8 hours and use eye drops often! for daily ones you can wear them up to 10 hours but use eye drops all the time :)

For 1 Day Contact, you can wear it 24 hours, but I prefer 10-15 hours and always have eyedrops in your pocket to keep it hydrated. Also, you need to check the right side of contact lenses before putting them on your eyes ? If I make you feel irritated, you might need to take contact lenses out if needed. And let your eyes rest for a day if it needs to! Olens is one of the best brands of contact lenses that moisturising very well

To be honest, it depends on many factors like your own sensitivity and each lens itself. I personally wear mine for up to 14 hours a day while I have very sensitive eyes in general. So far I've only used the olens contact solution, so if you have difficulties when it comes to wearing contacts, the reason might be the contact solution. :)

Hi! I've been using Olen's lenses for years now and It doesn't seem to dry my eyes out that much. I used the 1 day lenses multiple times now, tried using it for the whole day too (12-14 hours) it doesn't irritate my eyes at all!

Hello! Usually I wear them for the entire day but the recommended length is usually 10-12 hours! As I have classes in the morning, I sometimes wear them longer than 12 hours but Olens is usually more moisturising and less irritable than other brands!
