Why did the packaging and name change from the blue and red colors to the blue and purple and the added name “Extra”? The ingredient list is the same.

I don't know about the change in colors on the package, but the "Extra" is not the same product as the regular Thera Teas. "Extra" gives a little additional lubrication and works well for day or night use.

Extra in what ingredients???? You fake advertising. The previous version without no extra is just 10 dollar. Now it's more expensive and same ingredie

I think the extra ingredient is trehalose, a lubricant but no better and perhaps not as good as CMC. So I agree. Another extra ingredient I'm not happy with is NA perborate which IS a (mild) preservative which should not be used more than 4x/day ( Google it).

Does the preservative free version contain trehalose?

New TheraTears® EXTRA® Preservative Free uses the same advanced formula as TheraTears® EXTRA®, but without preservatives in convenient single-dose vials. The TheraTears® EXTRA® formula contains trehalose and is extra moisturizing to rehydrate dry eyes, protect from further irritation and support your tear’s natural pH level.

Can you reclose the cap to use all day?

Because our product is preservative free, there are no added chemicals within the vial to protect the formula from any possible airborne contaminant or contamination from the tip coming into contact with any surfaces. Thus, they are FDA approved for single-use only, and you should discard any unused product after opening each vial.
