I found your original post and considering he was under a ReptiGlo 10.0, Just by turning it off you should see a difference.
Is he hiding? and if you were to move him into his basking spot (Basking light should still be on, Just turn the ReptiGlo off) will he stay basking or run and hide?
If he is not basking then you need to get him onto soft foods such as baby food as be will have a hard time digesting anything solid and may further complicate the situation.
Keeping his eyes closed could either be do to some damage to the retina caused by the
UVB light, Which is temporary. your beardie would feel like we would with sand in our eyes. Or it could be due to a lack of strength... Should not be the case if he just ate though.
Taking him outside for a little while would also do him a world of good, not too long though as his skin has only every gotten artificial lighting and will take some time to get used to the sun... they can easily burn during this time.
Make sure you keep him
hydrated, oral fluids are best. You can either drip it onto his nose and allow him to lick it off, or use a medicine dropper right into his mouth. Use water, or if possible mix some pedialite or gatorade with the water to help get some electrolites back into him. If this is not possible you can also give him a warm
bath making sure his vent is submerged. once again you can use pedialite or gatorade to
bath him just make sure to use the clear stuff so you do not dye his skin. If he is weak, do not stray more than a few feet from him while he in
bathing, they can easily drown in very little water if he is not able to hold himself up.
