More Info


Acute conjunctival edema, often resulting from irritation or trauma, such as rubbing the eyes, can lead to swelling of the conjunctiva, which is the clear tissue covering the white part of the eye. Recovery time can vary depending on the severity of the irritation and individual healing responses. Typically, mild cases may resolve within a few hours to a couple of days, while more severe cases could take longer, potentially up to a week or more.
1. Recovery Time: The recovery time for acute conjunctival edema can vary significantly. If the edema is mild and caused by minor irritation, you might notice improvement within 24 to 48 hours. However, if the swelling is more pronounced or if there is an underlying condition, such as an allergic reaction or infection, it may take several days to a week for the swelling to fully subside. It's essential to monitor your symptoms; if the swelling persists beyond a few days or worsens, you should consult an eye care professional for further evaluation.

2. Contact Lens Use: Regarding the use of contact lenses during this period, it is generally advisable to avoid wearing them until the swelling has completely resolved. Wearing contact lenses can exacerbate irritation and may lead to further complications, such as increased risk of infection or discomfort. The lenses can trap allergens or irritants against the eye, prolonging the healing process. If you must wear lenses, consult with your eye care provider for personalized advice based on the severity of your condition.

In addition to these considerations, it's important to practice good eye hygiene. Avoid rubbing your eyes, as this can worsen the swelling and introduce bacteria. If you suspect that allergies are contributing to your symptoms, consider using antihistamine eye drops or oral antihistamines, but consult with a healthcare professional before starting any new medication.

If you experience additional symptoms such as pain, discharge, or changes in vision, seek medical attention promptly. These could indicate a more serious condition that requires treatment. Always prioritize your eye health and consult with an eye care professional for tailored advice and treatment options.
