Hello,
Swelling and pain in the the eyelid happens when fluid collects in the tissues around your eye. It can be due to infection or 
injury. Do continue to apply Visine eye drops, it will help to clear away the 
redness. 
Polysporin eye drops will help to reduce any infection in the eye. You may have itching or pain also but avoid touching or scratching your eyes.
In case of dry eyes, use of 
artificial tears will help to keep your eyes moist. You can take 
acetaminophen, one stat after food to help reduce swelling, soreness, inflammation and pain in the eyes. He should give the eyes rest. Cold compress may be helpful. If your brothers vision is affected and the symptoms are persistent, he is advised to get clinically examined by an eye specialist, he will be treated accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
