Aston Vision Science's clip-on filter

Aston Vision Sciences (AVS), a spin-out from Aston University’s school of optometry, has launched its first product to market; a clip-on fluorescein filter for optometrists to use when examining eye injury, dry eye conditions and contact lens fit.

The AVS fluorescein filter is said to be robust and long lasting, costing a sixth of the price of conventional fluorescein filters. It has a unique colour formula to ensure maximum contrast and definition for optometrists when examining an eye.

The filter attaches to a slit lamp for hands-free use and AVS said it offered a low-cost solution to practices and hospitals to upgrade existing equipment to gold standard recommendations.
