Here are some of the key features of an eye drop bottle:

1. Precision dropper tip: The dropper tip of an eye drop bottle is usually made of a soft, pliable material that allows for easy, precise delivery of the medication. It is designed to fit comfortably over the eye without causing any discomfort or irritation.

2. Leak-proof design: Eye drop bottles are designed to prevent leaks and spills, which can waste medication and potentially cause infection. The bottles are typically made of a sturdy material that can withstand accidental drops and knocks.

3. Air-tight seal: To ensure the medication remains effective, eye drop bottles are designed with an air-tight seal that prevents moisture and air from getting in. This helps to maintain the integrity of the medication and prevent the growth of bacteria.

4. Clear markings: Eye drop bottles are typically marked with clear measurement indicators that allow for accurate dosing of the medication. This helps to prevent over/under-dosing and ensures that the patient receives the full benefits of the medication.

5. Sterile packaging: Eye drops are generally packaged in sterile containers to prevent contamination and ensure the safety of the patient. This means that the bottles are typically sealed and sterilized prior to use.

Overall, eye drop bottles are an essential component of the ophthalmic industry. They are designed with the patient's needs in mind, ensuring that the medication is delivered accurately and safely, while also allowing for easy storage and transport of the medication.
