It is great to see a robust, regulatory approved yellow filter based on our research, become available for all those slit lamp biomicroscopes that don’t have one built in. A yellow filter is vital for optimised viewing of fluorescein on the ocular surface and its spectral transmission needs to be carefully selected. In addition, the AVS filter clips in place, making examination of the eye easier”

"The yellow filter is an amazing asset to improve the fluorescein visualisation of the cornea epithelial surface for subtle changes that may be easily missed otherwise. It is also a great teaching tool for junior ophthalmology trainees, optometrists and nurse practitioners who are starting to learn how to look for these changes as it clearly highlight them even with minimal fluorescein staining"

Tear film break up in action

Fast changes in tear film composition give rise to darker regions indicating the possibility of dry eye disease which become apparent with the fluorescein filter.
