The Color Filter Bar Set is the most efficient way for patients to determine their ideal tint. This is very important for patients who are light sensitive, especially those who have been diagnosed with Traumatic Brain Injury (TBI).
Each of the four color bars in the kit consists of four shade densities. Your patient can try 16 different tints very quickly without the need to put on and take off glasses. The absorption number for each tint concentration is engraved on the product.
This product was designed by Gulden in partnership with Dr. Ruth Shoge of the Eye Institute of Philadelphia.
