How much is a glycerin eye drop worth?

Let’s take a look at how much consumers are paying:

$16.87 (10mL)
$1.69 per mL
$0.08 per drop

$22.50 (10mL)
$2.25 per mL
$0.11 per drop

$23.78 (10mL)
$2.38 per mL
$0.12 per drop

$29.00 (10mL)
$2.90 per mL
$0.15 per drop

$85.95 (3mL)
$28.65 per mL
$1.43 per drop

$199.00 (3mL)
$66.33 per mL
$3.32 per drop

It seems we have a couple of outliers.

Let’s make sure this is an apples-to-apples comparison.

We’ll compare just drops that list the same active and inactive ingredients:

1. Eyeganics Organic Tears

Ingredients: Glycerin 0.2%, sodium chloride (salt), water

$29.00 (10mL)
$2.90 per mL
$0.15 per drop

2. Regener-Eyes Lite

Ingredients: Glycerin 0.4%, sodium chloride (salt), water

$85.95 (3mL)
$28.65 per mL
$1.43 per drop

3. Regener-Eyes Pro

Ingredients: Glycerin 0.5%, sodium chloride (salt), water

$199.00 (3mL)
$66.33 per mL
$3.32 per drop

Hm. Similar results.

Let’s try comparing based on the glycerin concentration, in case that’s a factor.

Following are all of the eye drops we could find that are registered with the FDA and list glycerin as the sole active ingredient.

Print too small? Sorry. Try right-clicking on the image and choosing “Open image in new tab”

Okay, so -

• $2.22 per mL = average cost for the 11 eye drops with 0.2% to 0.25% glycerin

• $28.65 per mL = Regener-Eyes Lite (0.4% glycerin)

• $66.33 per mL = Regener-Eyes Pro (0.5% glycerin)

• $2.56 per mL = average cost for the 3 eye drops with 0.5% to 1.0% glycerin

Which of the following best describes your response to this information?

a) This doesn’t mean anything to me. I am convinced that Regener-Eyes contains secret sauce intentionally omitted from the label to hide it from the FDA. I don’t mind the idea of ingredients being concealed from consumers and doctors, because I believe in the product.

b) You have got to be kidding me.
