I slept with my contact lenses in... I have a swollen and red inner corner of my eye...

Based on the symptoms described, it is important to avoid wearing contact lenses until the swelling and redness in the inner corner of the eye improves. Applying lubricating drops from the same brand as your contact lens solution can help. Additionally, applying cold compresses to the affected eye three times a day for 10 minutes each time may help reduce swelling. If there is no improvement in a few days or if the condition worsens, it is advisable to see an optometrist for a thorough examination of the eye.
