Excessive blinking while watching TV is often due to eye strain, dry eyes, or allergies. Mizol is an antihistamine/decongestant drop used for allergies. If his blinking is caused by dry eyes from screen time, preservative-free lubricating eye drops (like carboxymethylcellulose) are excellent, safe alternatives. For allergic symptoms, gentler prescription drops like Olopatadine are often preferred for children over decongestants. Since he was also prescribed glasses, correcting his vision will significantly reduce eye strain. Please consult his ophthalmologist before switching medications to ensure the alternative is appropriate for his specific diagnosis.

Long-term use of drops containing naphazoline, such as Mezol eye drops, can cause rebound redness and may worsen your symptoms over time. It is advisable to stop frequent use of such drops and consult an eye doctor for proper evaluation and safer long-term treatment.
