The presence of UV absorbers in some GP materials may cause fluorescein pattern detail to be less visible, when viewed with the white light and cobalt blue filter most common in slit lamps.
To aid in evaluating fluorescein pattern, these Wratten #12 filters attach unobtrusively to the front of the slit lamp using a small Velcro strip (included).
With the filter in place, the green glow of the illuminated fluorescein is enhanced for easier viewing.
For laboratory and professional use only (not approved for patient use).
