My OH stupidly went to bed with his contacts still in one night last weekend. The next morning one contact was still in his eye but the other was missing - he assumed it fell out during the night. The missing contact has now just appeared in his eye again this morning - it must have got stuck up under his eye lid - and has now been removed.
What should he do now? Obviously he's at a risk for getting an infection from the contact being in so long. He said his eye feels fine but the inner corner of it was a bit red yesterday evening. He said he had been rubbing his eyes a lot at work yesterday (he is also prone to bad hayfever/allergies) so thought it was just from that, and the redness did calm down a bit when he stopped rubbing.
Should I insist he goes to the optician to check for any issues or wait and see how his eye is over the weekend?
