Is the vision affected?
How long back did he have trauma?
It is always recommended to see an ophthalmologist after trauma to the eyes. Watering and pain in the eyes after trauma with a rubber band could be due to corneal epithelial defect, raised eye pressure, traumatic uveitis etc. Some complications may not develop suddenly but appear later. If corneal epithelial defect is present your husband may require topical anti-biotics, dilator drops or lubricants. Uveitis will require steroid drops. If eye pressure is high pressure reducing medications may have to be given since raised eye pressure can harm the optic nerve of the eye. I would recommend you to see an ophthalmologist. Thanks and best wishes.
