Polyvinyl alcohol eye drops can be used as a lubricant to prevent or improve irritation symptoms such as eye dryness, foreign body sensation, and eye fatigue. The ingredients of this eye drop are natural and safe, so let's follow Ruizhu today to understand what polyvinyl alcohol eye drops are.
First, let's take a look at the mechanism of action of polyvinyl alcohol eye drops. Its main component is polyvinyl alcohol, which is a polymer with good viscoelasticity. By forming a protective film around the eye area, polyvinyl alcohol eye drops can help keep the eye area moisturized, reducing eye fatigue and discomfort. For example, Ruizhu polyvinyl alcohol eye drops are one of the most commonly used artificial tear eye drops, which can be used as a lubricant to prevent or improve irritation symptoms such as eye dryness, foreign body sensation, and eye fatigue. Moreover, Ruizu polyvinyl alcohol eye drops do not contain any preservatives and can be used for a long time. They are all individually packaged, which is easy to carry and use at any time, but if it is opened, it should also be used up on the same day to avoid the deterioration of the liquid medicine after a long time.
In addition, Revizo has also summarized a detailed guide on the correct use of polyvinyl alcohol eye drops
Clean your hands: Before applying eye drops, it is essential to make sure that hands are thoroughly cleaned. This is to prevent bacteria from getting into the eyes and causing infection.
Check the solution: Before use, check whether the liquid medicine is clear and free of impurities or discoloration. If in doubt or if you notice any abnormalities in the solution, you should stop using it immediately and consult a doctor.
Correct eye drops: Gently separate the lower eyelid and drop the eye drops into the lower conjunctival sac (i.e., the conjunctiva between the lower eyelid and the lower eyeball). Use 1-2 drops per eye at a time. Avoid dropping eye drops directly onto the eyeball to avoid causing discomfort.
Press the lacrimal sac: To prevent the liquid from flowing into the nasopharyngeal cavity, gently press the lacrimal sac (located at the inner corner of the eye) for 1-2 minutes after the eye drop. This ensures that the liquid is fully applied to the eye area and not absorbed by the nasal cavity.
Avoid direct contact with the bottle finish: When removing eye drops, do not allow the mouth of the bottle to come into contact with eyes or other surfaces to avoid contamination. In case of accidental contact with other surfaces, the neck should be replaced immediately.
Maintain a certain interval time: In general, if you need to apply more than one different type of eye drop, you should wait at least 5 minutes after each application before using another type of eye drop. This is because the simultaneous use of multiple drugs may cause chemical reactions that can reduce their effectiveness or cause discomfort.
Follow your doctor's instructions: Although polyvinyl alcohol eye drops are a relatively safe product, everyone's situation is unique. Therefore, be sure to follow your doctor's instructions to determine the best regimen and dosage for you.
Pay attention to the reaction: During use, eye reactions should be closely observed. If any discomfort, redness, swelling, itching, or other unusual symptoms occur, discontinue use immediately and consult a physician.
Pay attention to the expiration date and storage method: Make sure that the medicine has not expired and is stored as stated on the instructions. In general, eye drops should be stored in a cool, dry place away from direct sunlight and excessive temperatures.
Have a thorough discussion with your doctor: If you have any questions or concerns about the use of polyvinyl alcohol eye drops, you should discuss them with your doctor thoroughly. They can provide you with the most accurate and personalized advice and guidance.
