Vision Tests, Visual Acuity Calculators & Research Tools
Precision Vision. Proven Results.
Modern eye care relies on accurate measurement, careful analysis and a clear understanding of visual performance. From simple vision screening tools to advanced clinical calculations, these resources help interpret how well the eyes see and how visual outcomes are measured.
This collection of tools has been created to make vision science easier to explore. Here you will find visual acuity calculators, LogMAR conversion tools, online eye charts and simple screening tests that demonstrate how ophthalmologists measure and analyse vision.
LogMAR ↔ Snellen Vision Converter
LogMAR is a visual acuity measurement used in ophthalmology to analyse vision outcomes and convert clinical data into familiar formats.
20/20 Vision Probability Calculator
Estimate the probability of achieving 20/20 vision using mean LogMAR, standard deviation and sample size from clinical outcome data.
Refractive Surgery Outcomes Simulator
Condition-led vision treatment targets myopia, hyperopia, astigmatism and presbyopia using modern solutions.
