Visual acuity and contrast sensitivity changes in patients with maculopathy with yellow amber filter glasses

Purpose Macular disorders affect central vision, color perception, and contrast sensitivity (CS), with age-related macular degeneration being a typical example. This study assessed the effectiveness of yellow amber filter glasses in improving visual acuity (VA) and CS in patients with macular diseases. Patients and methods This descriptive cross-sectional study included 128 eyes from 105 Egyptian patients with various macular conditions. VA (using the Snellen chart) and CS (Pelli-Robson test and Vector 1000E) were measured with and without yellow amber filter glasses. Results Significant improvements were observed across tests. Best-corrected visual acuity improved from a mean of 0.779 to 0.699 ( P <0.001). The Pelli-Robson test showed enhancement from a mean of 0.613 to 0.695 ( P <0.001). For the Vector 1000E test, CS improved across spatial frequencies: at 3 cycles per degree (CPD) from 1.544 to 1.618, at 6 CPD from 1.619 to 1.773, at 12 CPD from 1.285 to 1.410, and at 18 CPD from 0.732 to 0.819 (all P <0.001). Conclusion Yellow amber filter glasses significantly improved VA and CS in patients with macular diseases, regardless of age, sex, or comorbid conditions.
