  • Eyes are the critical sensory organ of the human being. Eyes provide organisms with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Most people have eye problems at one time or another. Some are minor and will go away on their own, or are easy to treat at home. Others need a specialist's care. The ophthalmic disorder or abnormalities of the eyes are associated with allergies, inflammation, infection; to counteract the same role of antihistamine, NSAID (Non-steroidal antiinflammatory drug), antibacterial, antifungal and antiviral drugs is very vital.
