Measure your eyesight accurately and easily at home, in school, hospital, or anywhere with the iSight Test. Designed by eye doctors, it contains letter and picture charts to test children as young as 18 months through to adult. Full instructions and explanations are included and test scores are displayed and interpreted

The iSight Test is designed with mums, dads and carers in mind to allow testing of vision in familiar surroundings where children are most likely to perform at their best, so parents can check and monitor their child’s eyesight at home with confidence.

The iSight Test can also be used to help monitor changes in people with Age-Related Macular Degeneration (ARMD), which is the most common cause of vision loss in those aged over 50 in the western world. ARMD causes a gradual loss of central vision, which can often interfere with near vision tasks such as reading, recognising faces, and driving. However, the loss of acuity can be difficult to appreciate, especially if there is established scarring, or when it develops in the non-dominant eye. By using iSight Tests built-in log, subtle changes over time can more easily be detected, allowing timely review and treatment.

Professionals will find the iSight Test invaluable as a portable visual acuity test in clinic, at the bedside or on home visits. The test was designed by two ophthalmologists and a paediatric orthoptist. It uses US and UK approved letters for testing older children and adults, and the Kay Picture Test to test children as young as eighteen months. Both tests are fully researched and validated with many years of clinical use.

The iSight Test comprises distance letter and picture tests and near vision testing. Near vision is presented in print sizes N48 to N5 as short story paragraphs that have been carefully worded to be easy for children to read. For younger children the near vision version of the Kay Picture Test is available on some platforms.

Testing visual acuity with the iSight Test is simple and quick. For parents and non eye-care professionals there is general information on what to consider and expect when vision testing, as well as specific step-by-step instructions for letter and picture testing.

The test process itself is easy. Follow the on-screen instructions and indicate whether a picture or letter can be seen and identified. The test ends automatically and the visual acuity score is shown on screen, with interpretation of the results immediately available. For more information go to www.isighttest.com
