Clinical Study of Astaxanthin for Dry Eye: Confirmed Benefits for Visual Health

Dry eye syndrome is an increasingly common disorder, especially among those who spend many hours in front of electronic devices. The main symptoms include dryness, burning, difficulty focusing and eye fatigue. Fortunately, there are targeted dietary supplements such as CurIAL βeta™, whose innovative formulation contains Natural astaxanthin AstaZine®, derived from microalgae haematococcus pluvialis, combined with lutein and anthocyanin for a complete synergistic action.

A recent independent clinical study has confirmed the effectiveness of this formulation, with a particular focus on the extraordinary benefits offered by astaxanthin to improve visual comfort and significantly reduce dry eye symptoms.

How and why was this study conducted?

Researchers wanted to investigate the beneficial effects of astaxanthin on eye health, in light of its powerful antioxidant action and its demonstrated ability to improve retinal microcirculation. In fact, astaxanthin is known for:

• Effectively reduce oxidative stress in the retina.
• Improve blood flow near the optic nerve.
• Support visual function, especially during prolonged use of digital screens.

The clinical study involved 44 healthy adult participants with clear symptoms of eye strain due to continuous exposure to electronic devices. Participants were divided into two groups, with daily treatment for 6 weeks:

• One group received capsules containing astaxanthin (along with lutein and anthocyanin).
• A placebo group received capsules without active ingredients.

The aim was to verify whether astaxanthin could alleviate the typical symptoms of dry eye, improving the ability to focus and general visual well-being during prolonged activities on a PC or smartphone.

What benefits did the study confirm?

Clinical results showed significant benefits in subjects taking astaxanthin compared to placebo:

• Improvement of pupillary accommodation capacity (focus response), particularly important for reducing visual fatigue during prolonged sessions in front of digital screens.
• Noticeable decrease in dry eye symptoms, such as dryness, difficulty focusing, and burning.
• Improved subjective perception of visual quality and ocular well-being, confirmed by validated and standardized questionnaires.

These results confirm that oral astaxanthin supplementation can have a long-lasting effect in supporting and improving ocular health, especially in the presence of prolonged exposure to blue light from screens.

Why can we trust this study?

The study was conducted following the most rigorous international scientific standards:

• Double-blind, randomized, placebo-controlled design, guarantee of impartiality and accuracy of the results.
• Objective and standardized assessments such as pupillary response and validated questionnaires, which ensure clinical robustness of the collected data.
• Compliance with international ethical and scientific guidelines (Declaration of Helsinki), supervised by independent committees.

These aspects confirm the reliability and scientific value of the conclusions obtained.
