The refractive error and vision impairment estimation with spectacle data study

Purpose: To investigate whether spectacle lens sales data can be used to estimate the population distribution of refractive error among patients with ametropia and hence to estimate the current and future risk of vision impairment. Design: …

Big Data Analysis of Vision Screening Standards Used to Evaluate Fitness to Drive

Purpose Visual acuity (VA) assessment is the most commonly performed vision screening method for drivers. The standards and repeat assessment intervals used, however, are arbitrary, lack an evidence base and are highly variable across different …

Macular Pigment Response to Lutein, Zeaxanthin, and Meso-zeaxanthin Supplementation in Open-Angle Glaucoma: A Randomized Controlled Trial

Purpose To evaluate macular pigment response to carotenoid supplementation in glaucomatous eyes. Design Double-masked, randomized, placebo-controlled clinical trial, the European Nutrition in Glaucoma Management Study (ClinicalTrials.gov identifier, …

Application of big-data for epidemiological studies of refractive error

Purpose: To examine whether data sourced from electronic medical records (EMR) and a large industrial spectacle lens manufacturing database can estimate refractive error distribution within large populations as an alternative to typical population …

Macular Pigment Optical Density Fluctuation as a Function of Pupillary Mydriasis: Methodological Considerations for Dual-Wavelength Autofluorescence

Purpose of the study: Macular pigment (MP), comprising the dietary carotenoids lutein, zeaxanthin and meso-zeaxanthin, is believed to benefit eye health and vision. Numerous clinical and research devices and techniques are currently available to …

Smartphone use as a possible risk factor for myopia

Clinical relevance This study demonstrates an association between myopia and smartphone data usage. Youths now spend more time participating in near tasks as a result of smartphone usage. This poses an additional risk factor for myopia …

Do Smartphones Hurt Our Eyes by Causing Shortsightedness?

Shortsightedness is caused by the eye growing too long, which results in faraway objects, such as the board in school, appearing blurry. People who are shortsighted wear glasses or contact lenses to see better. But would not it be incredible to …

Investigation of Surrogate Biomarkers Associated with Macular Pigment Status in a Group of Older Irish Adults

SIGNIFICANCE Macular pigment (MP) confers potent antioxidant and anti-inflammatory effects at the macula; however, its optical density in the eye is not routinely measured in clinical practice. PURPOSE This study explored a range of surrogate …

Association of total zinc intake with myopia in US children and adolescents

SIGNIFICANCE: This present study advances our knowledge on the role of lifestyle factors in myopia (short-sightedness), specifically dietary factors. It has been suggested in previous studies that lower zinc status is associated with myopia; however, …

Lutein and zeaxanthin: The possible contribution, mechanisms of action and implications of modern dietary intake for cognitive development in children.

Background: Studies suggest that lutein and zeaxanthin may be important for cognitive development in children, but a comprehensive evidence synthesis is lacking. The purpose of this evidence synthesis was to analyse the available data regarding the …
