Looks like they changed the formula when they recently changed the packaging...Is this still preservative free? I can't find where it says that on box

This has a preservative that apparently changes disapeers when exposed to oxygen when you blink your eyes. For those using drops 4 or more times a day, it's recommended that you use something that isn't transiently preserved, as this formula is now. When they put them in the bottles, they often now use transiently preserved as opposed to plain old preserved. I've too been searching for my mother who has eye problems. Some presevatives somehow disapeer when you blink your eyes, while some do not. It's crazy making; but, I'd like to know which preservatives ARE transient and which are not. That would be useful information. The purest or those with most sensitive eyes to preservatives should still look beyond transiently preserved for smething that has NO preservatives at all. While the rest of us, using these less than 4 times a day or with orders to only use preservative free should take a pass on these probably. Although, I'm not a doctor; just someone researching for my elderly mom.

Can I use this while wearing contact lenses?

Hi Yi W., that’s a great question! We recommend trying our “TheraTears® Contact Lens Comfort Drops”, which are FDA approved for use with daily wear and extended wear soft and rigid gas permeable contact lenses.

shelf life for thera tears

I ordered my bottle of Thera Tears on 1/31/14. The expiration date on the bottle is 11/2015. So it looks like the shelf life is close to 2 years.

Can it relieve visual fatigue after studying on computer?

Staring at a computer often means we don't blink enough. This can lead to eye fatigue and irritation, so I would say, "Yes." I, too, use the drops for this reason.

Ottimo prodotto. Chiedete al vostro oculista.

Unico collirio che posso usare, essendo allergica ai componenti utilizzati in Italia. Il prodotto per me è ottimo, contro l'occhio secco e la stanchezza da monitor e cellulare. L'uso di certi prodotti deve essere controllato dai professionisti, ma mi sento di consigliarlo, soprattutto in inverno. Peccato che la consegna abbia tempi biblici. Spero sia colpa della situazione particolare che abbiamo vissuto.

Didn't help with dry eyes.

Didn't help at all with my dry eyes. Got something from the pharmacy instead which actually solved my issues.

Best Eye Drops for Dry Eye

I get dry eye a lot and red eyes in the morning. For years I searched for drops that soothed my eyes instead of irritating them or making them feel dryer. These are soothing and refreshing for a great price. Have tried over a dozen brands and this is the best.
