While Cineraria eye drops are sometimes used in alternative medicine, there is limited clinical evidence that they can strengthen eye nerves or relieve severe environmental sensitivities. Since previous lubricating drops like Refresh Tears haven't provided lasting relief, your symptoms of dryness and light sensitivity may require a more targeted approach. I highly recommend consulting an ophthalmologist. They can properly evaluate your eyes, check for underlying dry eye syndrome or nerve sensitivity, and guide you toward safe, effective treatments to help you find comfort.
