Lea Test
The Lea Test (pronounced: lee-uh test) is a commonly used visual acuity test in pediatric ophthalmology. It is named after its developer, Finnish ophthalmologist Lea Hyvärinen.
Etymology
The test is named after Lea Hyvärinen, a Finnish ophthalmologist and researcher who has made significant contributions to the field of visual impairment and rehabilitation. The term "Lea" is derived from her first name, and "test" refers to the examination procedure.
Description
The Lea Test uses a series of symbols or pictures, such as a house, a circle, a square, and an apple, which are easier for children to identify than traditional Snellen letters. The symbols are presented in decreasing sizes to assess the child's visual acuity. The test can be administered in various formats, including a wall chart, a flip chart, or a set of individual cards.
