More than 12 million bottles of Rohto eye drops are being recalled across the United States over concerns that the products may be contaminated. The recall affects six over-the-counter eye drop products and has raised concern because the drops are used directly in the eyes.

According to the FDA, the action has been categorized as a Class II recall. That classification means use of the affected eye drops could lead to temporary harm, including possible temporary injury to the eyes or short-term vision problems.

Rohto issued the recall notice after identifying a problem connected to the affected products. While the available recall summary does not detail every product listing, the scale of the action makes it one of the larger eye drop recalls in the country.

Contamination concerns involving eye care products are treated seriously because even temporary exposure can affect comfort, sight, and overall eye health. Consumers looking for details on the recalled items are likely to focus on the specific Rohto products included in the nationwide FDA recall.
