For over 90 years, the Good-Lite Company has led the industry with its illuminated cabinets, evidence-based eye charts like the LEA SYMBOLS®, and a comprehensive range of vision screening and testing products.

Founded in 1930 by Robert Good, MD, and his son, Palmer Good, MD, the company initially pioneered the Good-Lite medical headlight. Palmer expanded the product line to include vision testing equipment, establishing Good-Lite as a prominent name in the field.
