Standard household dishwashing liquid is generally considered a mild to moderate ocular irritant, not a corrosive agent. While the immediate reaction is intensely uncomfortable, the eye is remarkably resilient, and this type of exposure rarely causes long-term vision loss. Understanding the immediate physical reaction and knowing the correct steps ensures a quick and full recovery.
Immediate Symptoms and Sensations
The moment dish soap contacts the eye, the most pronounced symptom is a sharp, intense burning or stinging sensation. This discomfort is caused by the chemical interaction with the sensitive surface of the eye. It is typically followed by profuse, involuntary tearing as the eye attempts to flush out the irritant naturally. The surface of the eye, particularly the conjunctiva, will become visibly red, signaling irritation and increased blood flow. Many people also experience a temporary blurring of vision due to the disruption of the tear film and the presence of the foreign substance.
Essential First Aid Steps
Ocular Irrigation
Immediate and thorough ocular irrigation is necessary. Rinse the eye continuously and gently with clean, lukewarm tap water to dilute and wash away the chemical irritant. This process must be sustained for a minimum of 15 to 20 minutes, even if the stinging sensation subsides quickly. To effectively flush the entire surface, hold the affected eye open as wide as possible. Tilt your head so the affected eye is lower than the unaffected eye, preventing rinse water from flowing into the clean eye. Direct the stream of water from the inner corner of the eye toward the outer corner.
Contact Lenses and Aftercare
If you are wearing contact lenses, remove them immediately during the rinsing process. It is important to resist the urge to rub the eye, as mechanical friction can worsen irritation and potentially cause tiny abrasions on the corneal surface. After the full 15 to 20 minutes of rinsing, use sterile saline solution or artificial tears to help soothe residual dryness and discomfort.
When to Seek Professional Medical Care
While diligent rinsing resolves most dish soap exposures, certain signs indicate the need for professional medical evaluation. If irritation or foreign body sensation persists despite 20 minutes of continuous water flushing, seek care from an ophthalmologist or an emergency room. Prompt medical attention is required for any noticeable change in vision that does not clear up after rinsing.
Warning signs that require immediate medical attention include:
- Persistent blurriness, double vision, or a decrease in visual acuity.
- Severe sensitivity to light (photophobia).
- Increasing pain over time.
- Visible changes to the structure of the eye, such as swelling, discharge, or cloudiness of the cornea.
If the product involved was an industrial-strength cleaner or a highly concentrated detergent tablet or pod, call a local Poison Control Center or emergency medical services. These highly alkaline or concentrated formulas pose a greater risk of chemical burn, which can penetrate eye tissue more deeply.
Why Dish Soap Irritates the Eye
The intense irritation caused by dish soap is primarily due to surfactants, the active cleaning ingredients. These surface-active agents disrupt the eye’s delicate tear film, which has a crucial outer lipid layer protecting the corneal surface. When surfactants contact the eye, they strip away this protective layer, leaving superficial corneal cells exposed and irritated, which triggers the burning sensation.
Another element is that most common dish soaps are slightly alkaline, often having a pH between 9 and 10. This pH difference is significant because alkaline substances are more damaging to eye tissue than acidic substances. Alkaline chemicals can penetrate the cornea more rapidly, causing stinging and temporary cellular disruption. The combination of surfactant action and pH imbalance explains the immediate discomfort, though standard dish soap is not typically corrosive enough to cause permanent damage.
