We are a small family business that was founded by orthoptist, Hazel Kay when she researched and developed the Kay Picture Test vision testing system to enable earlier visual acuity measurements of very young children and those with learning disabilities.Over the years we have designed other complementary paediatric orthoptic tests, providing a range of fixation, occlusion, reward stickers, and therapy products. We also supply paediatric colour vision and stereo acuity tests.Our visual acuity tests are used by the eye-care professions (optometrists, ophthalmologists and orthoptists) plus school nurses, health visitors, teachers of the visually-impaired, paediatricians and others.Hazel Kay continues to work as an orthoptist and personally researches and trials all new products for their suitability with young children.
