About this study
Several recent clinical trials have highlighted the potential role of Product in promoting eye health.product whose structural and functional characteristics make it a promising bioactive compound in the prevention of several human diseases as well as in the maintenance of a good health status. it might relieve eyestrain in people using computer monitors as suggested who conducted a double-blind randomized clinical trial by enrolling visual display terminal workers and prescribed them product or placebo. Study outcomes were objectively evaluated by using a proper instrumentation to measure eye muscle endurance. Subjects receiving Product experienced a significant relief from eyestrain compared to the placebo group.

What is being measured
The primary outcome is the main question the study is designed to answer.
Computer Vision Syndrome-Questionnaire
To assess the effect of 84 days of IP consumption on severity of the symptoms using Computer Vision Syndrome-Questionnaire.The two levels of intensity, or strength of the symptom, will be graded similarly, on a scale of 1 to 2 points, where moderate = 1 and intense = 2. In the analysis, a symptom rated as never occurring will be treated as 0 (none) on the intensity scale.
The overall assessment will be conducted by obtaining the total score for DES. The result of frequency X intensity will be recorded as: 0 = 0; 1 or 2 = 1; 4 = 2. If the total score is ≥ 6 points, the participant will be considered to be suffering from digital eye strain. It is further categorized as mild DES (score = 6-12), moderate DES (score = 13-18), and severe DES (score = 19-32)
Measured: Screening before playing videogames on digital device

Primary outcome
Computer Vision Syndrome-Questionnaire
Time frame: Screening before playing videogames on digital device
To assess the effect of 84 days of IP consumption on severity of the symptoms using Computer Vision Syndrome-Questionnaire.The two levels of intensity, or strength of the symptom, will be graded similarly, on a scale of 1 to 2 points, where moderate = 1 and intense = 2. In the analysis, a symptom rated as never occurring will be treated as 0 (none) on the intensity scale. The overall assessment will be conducted by obtaining the total score for DES. The result of frequency X intensity will be recorded as: 0 = 0; 1 or 2 = 1; 4 = 2. If the total score is ≥ 6 points, the participant will be considered to be suffering from digital eye strain. It is further categorized as mild DES (score = 6-12), moderate DES (score = 13-18), and severe DES (score = 19-32)

Where is the study taking place?
The record lists 3 sites in India. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Computer Vision Syndrome-Questionnaire (time frame: Screening before playing videogames on digital device). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05602402, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
