$49.00
The Ohlson Vital Stain Enhancement Filters is a yellow and red filter side-by-side, that easily fits in your pocket. Use the yellow filter for fluorescein examination of rigid gas permeable contact lens fit and high molecular weight fluorescein examination of silicone hydrogel contact lens fit. The red filter is used for red lens test and lissamine green examination for dry eye patients.
The benefits of using the yellow filter increases the visibility of the fluorescein pattern; the red lens increases the visibility of lissamine green staining on the bulbar conjunctiva.
The filter comes in a "flip-out" designed case to prevent scratching of the filter and measure 3" in diameter.
