How to treat dry eyes from contacts?

Rewetting drops. If one has dry eye from the use of contacts one should think of laser correction. If dry eye existed prior to contact lens wear then consistent use of cl rewetting drops during the daily wear would help. Assuming that the lenses are removed and stored every night it would also be helpful to use lubricants at night such as gel drops which are thicker than normal rewetting or regular dry eye drops.
Dry eyes. Dry eye is very common. I would try artificial tears frequently during the day, ointment at night, warm compresses 1-2 times a day, and omega-3 fatty acid supplements. If no improvement, see an eye doctor.
Artificial tears. Also, make sure you have a good fit. Rejection of lenses (gpc) can cause dryness- need to be checked by the eye doctor.
