A team of Japanese researchers wrote: “The main findings of this study are that VDT surgery temporarily impairs eye-hand coordination and smooth pursuit eye movements, while astaxanthin, lutein, and zeaxanthin improve vision damage caused by VDT surgery.”
The study, published in the journal Nutrients, was supported by Senju Pharmaceuticals and evaluated a combination of astaxanthin, lutein and zeaxanthin from natural ingredients supplier BGG World.
Long-term use of VDTs can result in decreased blink rate and increased tear evaporation, leading to dry eye syndrome and associated symptoms including ocular discomfort, fatigue, and blurred vision.
The Japanese research group noted, “It has been reported that VDT surgery may cause sustained tension in the ciliary muscle because the terminal is observed at close range for a longer time, resulting in a decrease in the amplitude of accommodation.” “VDT surgery may cause tension in the ciliary muscle due to tension in the extraocular muscles. Decreased ocular function. Therefore, we hypothesize that the temporal coordination of the eyes and hands and smooth pursuit eye movements induced by the VDT procedure may be associated with decreased accommodation and oculomotor function.”
In describing the direction of their research, the researchers cited evidence that astaxanthin (derived from the microalgae Haematococcus pluvialis) improves accommodation, oculomotor and body functions, as well as lutein and zeaxanthin (most abundant (in green leafy vegetables, most effective in marigold flowers) .) will accumulate macular pigment to absorb the blue light emitted by the VDT, improving visual processing speed and contrast sensitivity. googletag.cmd.push(function () { googletag.display(‘text-ad1′); });
This randomized, double-blind, placebo-controlled study involved healthy Japanese men and women aged 20 to 60 years who regularly played video games, used computers, or performed VDT. Participants were assigned to take 6 mg astaxanthin, 10 mg lutein, and 2 mg zeaxanthin (66 mg/capsule: pigment derived from Haematococcus pluvialis and 55 mg/capsule: marigold, manufactured by BGG Japan Co., Ltd., provided) or placebo with rice oil once a day for eight weeks.
The researchers assessed eye-hand coordination, smoothness of eye movements, and macular pigment optical density (MPOD) at 0, 2, 4, and 8 weeks after taking the softgels. The primary outcome was visual function (time and accuracy of eye-hand coordination, and visuomotor reaction time during smooth pursuit eye movements).
“Eight weeks after VDT surgery, eye-hand coordination was significantly improved in the active group,” the study concluded. “However, the effect of the supplement on the smoothness of pursuit eye movements was not significantly improved. MPOD levels were also significantly improved in the active group.” . Increase.”
Limitations reported include lack of control over the levels of astaxanthin, lutein, and zeaxanthin in the daily diet, and uncertainty about whether these benefits can be attributed to additive or synergistic effects.
“Although we believe that the combination of these nutrients is critical for effects on eye-hand coordination due to the different mechanisms of action of astaxanthin and lutein/zeaxanthin, further research is needed to elucidate the mechanism for the beneficial effects of these nutrients,” the researchers said. marked.
BGG World contributed additional ingredients to the study and conducted its own research to confirm the ingredients’ benefits for various aspects of eye health.
“While the two previous studies (one on Astazine alone and the other on AstaZine + MyrtiPro + Lutein) focused on visual functions (visual acuity, pupillary accommodation, OI, etc.) before and after VDT work, this The study’s effects were studied by BGG Americas. and Algae Health Sciences CEO Shaheen Majid told NutraIngredients-USA.
He added that in the future there may be interest in conducting combination studies in eye care beyond lutein/zeaxanthin, with the goal of introducing new synergistic combinations with clinically proven ingredients.
