Do you have contact lens solution?
so-lu-TSYO-ne — four syllables. 'Lenti a contatto' — LEN-ti a kon-TAT-to.
Ask at a pharmacy when you have run out of contact lens solution while travelling.
'Soluzione per le lenti a contatto' is the full phrase. You can shorten it: 'soluzione per lenti'. Types: 'soluzione multifunzione' (multipurpose solution, most common), 'soluzione salina' (saline only), 'liquido per lenti rigide' (rigid lens solution). Italian pharmacies and parapharmacies stock these without prescription.
Avete anche i contenitori per le lenti?
Do you also have lens cases?
Lens cases ('contenitori') are often sold separately or bundled with solution
Avete collirio per gli occhi stanchi?
Do you have eye drops for tired eyes?
'Collirio' = eye drops. 'Occhi stanchi' = tired eyes — very common product in Italy
Ho gli occhi rossi. Cosa mi consiglia?
I have red eyes. What do you recommend?
Red eyes may need antibiotic eye drops (prescription) or simple lubricants (OTC)
Italian pharmacies ('farmacie') carry a full range of optical accessories and eye health products, especially since opticians ('ottici') are separate shops and are not open 24 hours. The pharmacist can advise on eye drop types: lubricants ('lacrime artificiali'), vasoconstrictors (for redness), and antihistamines (for allergic eyes). Prescription antibiotic eye drops for conjunctivitis require a doctor's note.
