Written by Joyce Smith, BS. This study finds that cyclic illumination of low light intensity (200 lux) for 14 days produced retinal degeneration; however, shielding 60% of damaging blue light may protect retinas from light damage thus providing a method for protecting eyes from the damaging effects of blue light.

Written by Angeline A. De Leon, Staff Writer. Researchers demonstrated that emission of blue light energy from LCD screens was associated with damage to retinal photoreceptor cells of the eye; therefore, LCD screens that emit lower levels of blue light may be more appropriate for protecting consumers’ eye health by reducing light-induced retinal damage.

Written by Joyce Smith, BS. This study suggests that smartphone use could not only aggravate subjective symptom indices such as the OSDI, VAS, and CVS but also induce tear film instability and oxidative stress indices in the tears and at the ocular surface. (more…)

Apricot kernel extract improved urban particulate matter-induced keratoconjunctivitis sicca in rats by significantly increasing tear volume, inhibiting damage to the corneal epithelium, decreasing corneal surface irregularity, and attenuating disruption of the mucin-4 layer by inhibiting MMP-9, IL-6, and TNF- α.

Written by Jessica Patella, ND. Eye strain significantly increased and eye lubrication significantly decreased in the participating healthy subjects who watched a tablet computer screen for one hour. (more…)
Written by Halima Phelps, Staff Writer. A daily three-month supplementation with 1000mg of EPA, 500 mg of DHA and 900 mg of α-linolenic acid significantly improved intraocular pressure in the 33 participating normotensive subjects compared to the controls. (more…)
Written by Angeline A. De Leon, Staff Writer. Of the 115 participating young healthy subjects, those who supplemented daily with 10 mg lutein and 2 mg zeaxanthin had significantly increased serum levels of macular pigment optical density and improvements in chromatic contrast and recovery from photostress.

Written by Angeline A. De Leon, Staff Writer. This study demonstrates how the antioxidant carotenoids lutein and zeaxanthin may support retinal microcirculation to maintain efficient blood flow and to prevent the onset of subclinical vascular diseases. (more…)
Written by Angeline A. De Leon, Staff Writer. Blue light-induced phototoxicity, a consequence of smartphone dependency, caused retinal damage in a rat model. (more…)
Written by Joyce Smith, BS. A six-month supplementation with omega-3 and -6 or omega-3 alone significantly contributed to retinal regeneration in a mouse model of dry AMD. (more…)
Written by Greg Arnold, DC, CSCS. Supplementation with three carotinoids, lutein, zeaxanthin, and mesozeaxanthin, for 12 months significantly improve macular pigment ocular density, decrease glare severity, and improved photostress recovery time in study participants. (more…)
Written by Joyce Smith, BS. A 6-month supplementation with lutein, zeaxanthin, and mesozeaxanthin significantly improved macular pigment optical density, temporal vision as well as sleep quality, contrast sensitivity, disability glare, photo stress recovery, headache frequency, and eye strain and fatigue. (more…)
Written by Greg Arnold, DC, CSCS. Participating subjects who ate one avocado a day for six months had significant increases in lutein levels, improved Short-Term Visual Memory and Sustained Attention scores as well as improved MPD, an indicator of improved cognitive function. (more…)
Written by Angeline A. De Leon, Staff Writer. Of the 38 patients with open angle glaucoma, those who supplemented with 50 mg of black current anthocyanins for 24 months had significantly less MD deterioration at the end of 24 months as well as a significant increase in blood circulation to the retina at the end of 18 months compared to placebo.

Written by Angeline A. De Leon, Staff Writer. In all four senile groups, the serum AGEs were significantly (Pb.001) lower in young control subjects thus corroborating the hypothesis that the advanced glycation process might have a role in cataract formation, which in diabetic patients is far more prevalent compared to nondiabetic cataract patients.

Written by Greg Arnold, DC, CSCS. Participating subjects who supplemented with lutein and zeaxanthin had significantly increased Macular Pigment Optical Density and Temporal Contrast Sensitivity Function which translated into increased temporal processing speed.
