The increase mucus production in the eyes could be a reflection of being systemically ill. Or, he could have another problems in the eyes like Dry Eye

1- Pick up in your local pharmacy eye wash and irrigate eyes; clean with a moist gauze.
2- After flushing and cleaning apply over the counter tear supplements.
3- Do the above 3-6 times a day.
4- As long as you keep the eye lubricated as above you will not see mucus.
5- The day he is to see your family veterinarian do Not flush or clean the eyes.
