Confusing Omega 3's. Ignore capsule size!
How much Omega 3 should I take for dry eye?
Simple question but the answer is a bit complex. Omega 3 supplements vary widely in their potency.
The following information is what I recommend in clinic. It is not applicable to everyone and talk to your eye care provider for more individualized information.
STEP 1 - Look at the label of your Omega 3 supplement and find these numbers:
Serving Size: e.g. 1,2,4 capsules
Capsule Size: e.g. 500mg to 1200mg
EPA content and DHA content in mg.
Ignore the serving size initially and find the EPA + DHA total
For dry eye, this total (EPA+DHA) needs to be 1000mg per day. Then figure out how many servings that you need to get ~1000mg/day of EPA + DHA
I often recommended up to 2000mg/day (EPA+DHA). The take away here is that the capsule size is irrelevant.
The form of the Omega 3 is important for bio-availability and triglyceride form is preferred.
See example below
On the above Krill Omega 3 label... one capsule (serving) has 75mg (EPA) + 45mg (DHA) = 120mg. For dry eye therapy I recommend >1000mg/day so... you would need 1000/120 = 8.33 ~ 8 capsules a day. (That's a lot!)
On this PRN De Omega 3 label ...
...one serving is 4 capsules which delivers 920 mg (EPA) + 920 mg (DHA) = 1840mg.
I would recommend 2-3 capsules of the PRN high potency product.
You can buy PRN and other Omega 3 product from mEYEspa.
Liquid Omega 3's generally have high potency and usually 1/2 a teaspoon will achieve the ~1000mg guideline but check the label.
Most important TIP... Take with food! Without food, even the best Omega 3 will not absorb properly and not deliver the desired result!

A recent patient of mine came up with this perfect description for the way her eyelids felt... Gritchy.
What did she mean and what causes this?
I wonder if this eye drop is still ok?
Scenario: you dig an eye drop bottle from deep in your travel bag. Expiration date on the worn label is next month .. is this drop still ok to put in your eye?
Do you blink to clear?
I suggest that clinically I see many patients mis-attribute transient screen blur to their glasses. This is most likely dry eye and counseling on drop use is usually met with some skepticism!
