The HRR Color Test is ideal for pediatric testing of congenital color deficiencies. HRR uses simple symbols (O, X, Triangle ) easily matched by children. Now we are offering a new laminated version to help avoid fingerprints and damage to the plates. This new laminated version uses a special matte finish laminate which reduces glare. The colors after lamination were tested using a spectrometer and showed almost no change compared to the original. The laminated version also includes our Reversible Occluding Glasses to make monocular testing for acquired color deficiencies easier.
