Infections in the body cavities like the ear, nose, and throat are very common and can occur due to various reasons such as bacteria, fungus, etc.
Many medicines are available in the market for the treatment of these kinds of infections. The most common method used is the application of ear drops and eye drops.
Key Takeaways
- Ear drops treat ear infections and reduce inflammation in the ear canal.
- Eye drops treat many conditions, including dry eye, allergies, and glaucoma.
- Ear drops are designed to be thicker than eye drops so that they can stay in the ear canal for a longer period, while eye drops are designed to be thinner and more watery so that they can be absorbed by the eye more easily.
Ear Drops vs Eye Drops
The difference between ear drops and eye drops is that ear drops are used for ear infections, while eye drops are used to treat eye infections and diseases. Ear drops can be applied to the outer ear or can be instilled in the middle ear but not in the inner ear. The eye drop is instilled in the eye pocket, which is created just under the eyelid.
Ear drops are a solution that is used in the treatment of ear infections or hearing problems. It is also used in cases to remove ear wax or in the cleaning of the ear.
Eye drops are aqueous solutions containing saline (0.9% of Sodium Chloride solution). The hypertonic nature of saline helps to reduce the swelling of the eye, which can be caused due to infection, trauma, or surgery.
