Visual photosensitivity thresholds (VPTs) were measured at two visits (≥1 month apart) under four lens conditions: no lens (NL), plano lenses (PLs), FL-41 lenses (FLs), and gray-filtering lenses (GLs). Lower VPTs indicate greater visual photosensitivity.<h4>Results</h4>Participants with TBI had significantly lower VPTs compared with non-TBI controls across all lens conditions at theInvestigative ophthalmology & visual science46https://www.ebi.ac.uk/biostudies/studies/S-EPMC12934528biostudies-literatureLight Filtering Lenses and Visual Photosensitivity in Individuals With Traumatic Brain Injury.PMC12934528Felix ERValdes Arias DLai JAlvarez GHurwitz BELam BLEcheverri Tribin FParel JABhatt SAguilar MCChou BGalor ADurkee HGonzalez APatel SPRowaan CfalseLight Filtering Lenses and Visual Photosensitivity in Individuals With Traumatic Brain Injury.<h4>Purpose</h4>The purpose of this study was to assess visual photosensitivity using the Ocular Photosensitivity Analyzer (OPA) with and without light filtering lenses in individuals with traumatic brain injury (TBI) and non-TBI controls.<h4>Methods</h4>This cohort study included 46 individuals with TBI (n = 46) and without TBI (n = 46) assessed from May 2021 to August 2023 at a large academic tertiary center.
