Astaxanthin in Retina Clear: What It Is and What the Research Says
Retina ClearThe red pigment that colors salmon and krill, studied for eye tiredness.
Retina ClearWhat it is
Astaxanthin is a carotenoid made by microalgae (Haematococcus pluvialis) and stored in salmon, shrimp and krill. In supplements it usually comes from the algae.
What research says
Small, short trials in adults who work at screens have tested astaxanthin for eye fatigue and focusing comfort, with modest positive signals in some and no change in others. The studies are small, often funded by makers, and use fixed doses that are printed on the bottle.
How Retina Clear uses it
Retina Clear names astaxanthin in its blend. Because eye-fatigue studies use specific daily doses, an undisclosed amount makes it hard to know whether the studied range is reached.
Quick answer
Is astaxanthin good for eye strain?
There are hints of benefit for screen-related eye tiredness, but the evidence is early and the amounts matter. Regular breaks and good lighting are the proven basics.
