How long can you wear contact lens without hurting your eyes?

How long can you wear contact lens without hurting your eyes?

What kind of lens?: Although there are extended wear contact lenses, I recommended daily removal before sleeping. Tears provide anti-infective compounds and enzymes which are in short supply during sleep when tear production drops. This puts the eye at greater risk for potentially sight threatening infections. ...Read more

Eyes hurts due to tight contact lenses. Could you tell me how long does it take for the eye to heal?

Eyes hurts due to tight contact lenses. Could you tell me how long does it take for the eye to heal?

Not tight?: Tight contacts rarely cause pain; it's the loose ones that are uncomfortable. Most contact lens irritations resolve without treatment in a day. If this has lasted longer than that, you need to see your eye doctor. ...Read more

I have recently tried to wear prescription multi-focal contact lenses. How long does it usually take for ones eyes to adjust.

I have recently tried to wear prescription multi-focal contact lenses. How long does it usually take for ones eyes to adjust.

1-2 weeks: I give most who try this about 1-2 weeks for trial. If they cannot adjust, I see them again for a recheck to make sure the power and fit are ok. About 50% of folks who try this, cannot adjust to it. They find the type of images produced by these lenses to be disturbing and not comfortable. Motivation is important also and previous contact lens wearers generally do better. ...Read more

I have red eyes and it always reoccur. I always use daily contact lenses to prevent infection. Am crew who hv to wear CL for long hours. Advice?

I have red eyes and it always reoccur. I always use daily contact lenses to prevent infection. Am crew who hv to wear CL for long hours. Advice?

Dry working place: By crew do you mean aircraft? If so, these are very dry atmospheres. You should apply a syrupy drop like Systane or Refresh prior to entering the work place. You can use ointment at night for sleep. Some get a little extra relief from daily ingestion of 2 tablespoons of Flax Seed oil. Do not use drops that say "gets the red out" as these are drying. If these fail, then see an ophthalmologist. ...Read more

1 week post op vitrectomy. How long should I wait to wear eye makeup and my contact lenses again?

1 week post op vitrectomy. How long should I wait to wear eye makeup and my contact lenses again?

Longer: You can wear contact lenses in the un-operated eye, but not in the operated eye until allowed by the surgeon. I would avoid eyeliner and makeup that could come in contact with the tear layer until allowed by the surgeon also. You are probably using postoperative eye drops, and these would not go well with contact lenses. ...Read more

How long to wait to wear contact lenses after gonioscopy (or whatever the exam is called where ophtalmologist puts a glass lense on your numbed eye)?

How long to wait to wear contact lenses after gonioscopy (or whatever the exam is called where ophtalmologist puts a glass lense on your numbed eye)?

Short time: The lens applied to your eye is on a gel which provides an optical link between the lens and the interior of your eye. The numbness usually disappears in 10 minutes at most and the normal tear flow will clean out the residual gel. So you can start to wear you contact lenses by the time the exam is completely over - probably 15 minutes after the gel aided exam. ...Read more

Can you wear contact lens when your eyes are red?

Can you wear contact lens when your eyes are red?

Not a good idea: Redness is a sign of a problem. As a general rule, anytime your eye is red, the first that you need to do is to take the contact lens out. There is strong likelihood that the redness is due to the contacts and keeping it in will only aggravate the situation (although your eye may feel better wearing the contacts). See your eye md for an evaluation. ...Read more

I am a contact lens wearer with very dry eyes - getting back to full time contacts wear, what tips do you have for me?

No contacts: Contact lens use will make your eyes more dry. If you already have very dry eyes at your young age, you may have serious dry eye symptoms later on in life. Consider not wearing contacts, or seek medical treatment now for your dry eyes. ...Read more
