The main side effects of water absorbent resin on the eyes are as follows:

Direct stimulation and injury
Chemical irritation: Some water absorbing resins may contain non polymerized monomers or other chemical additives, such as plasticizers, stabilizers, etc., which may cause chemical irritation to the eyes, leading to discomfort symptoms such as redness, pain, tearing, and photophobia.
Physical damage: If water absorbent resin particles enter the eyes, they may rub against the cornea and conjunctiva, causing physical damage such as corneal epithelial abrasions and conjunctival congestion, resulting in symptoms such as foreign body sensation, stabbing pain, and blurred vision in the eyes.
allergic reaction
Allergic conjunctivitis: Some people may be allergic to absorbent polymers, which can cause allergic conjunctivitis upon contact, resulting in symptoms such as itching, redness, and increased discharge of the eyes. In severe cases, it may affect vision.
Allergic eyelid dermatitis: Allergic reactions may also involve the eyelid skin, leading to symptoms such as redness, swelling, rash, itching, etc.
Other potential risks
Infection risk: If the absorbent resin stays in the eyes for too long or is not handled properly, it may breed bacteria and cause eye infections such as keratitis and conjunctivitis.
Visual impact: In severe cases, such as corneal injury or infection that is not treated in a timely manner, it may cause permanent damage to vision.
If the absorbent resin accidentally enters the eyes, rinse immediately with plenty of water and seek medical attention as soon as possible.
 When using products containing water absorbing resin, such as steam eye masks, attention should also be paid to choosing legitimate products and using them according to the correct usage methods and precautions to reduce potential harm to the eyes.
