Exposure to tarantula venom or their irritating hairs is a serious condition that requires immediate evaluation by an ophthalmologist. Please do not rub your eye. First, gently flush your eye with sterile saline or clean water. A doctor must examine your eye to check for embedded micro-hairs. Typically, treatment involves prescription corticosteroid eye drops (such as prednisolone) to control intense inflammation, alongside prophylactic antibiotic eye drops (such as tobramycin) to prevent secondary infection. Please seek urgent medical attention rather than self-medicating, as professional removal of any hairs and a tailored prescription are vital to safely protect your vision.
