Protect your Tono-Pen and your patients with genuine Ocu-Film.

Disposable and affordable, single-use, sanitized Reichert Ocu-Film + Tip Covers protect your Tono-Pen, and are easy to apply. Using genuine brand Reichert Ocu-Film + Tip Covers guarantees you are using tip covers that are specifically engineered for proper performance of your Tono-Pen.

Using non-Reichert tip covers may cause Tono-Pen readings to be erratic or inaccurate, and may result in difficulty obtaining measurements. Non-Reichert tip covers may also contaminate the Tono-Pen transducer, potentially voiding the warranty, and resulting in the need for costly service to the instrument.

Reichert Ocu-Film + Tip Covers are FDA cleared and are blue in color to assure the user that the tip cover is the genuine brand approved for use with Tono-Pen AVIA and Tono-Pen XL Applanation Tonometers.
