PRODUCT DETAILS

Composition

• Sodium hyaluronate (≈0.3%) – strong lubricant/hydrating agent
• Hypromellose (in some variants) – tear film stabilizer
• PHMB (preservative) or other mild preservative system
• Isotonic buffered solution (water, salts)

Key function: Artificial tears / eye lubrication

Indication / Use

Used for:

• Dry eyes (dry eye syndrome)
• Eye irritation due to:
• Screen use
• Air conditioning
• Wind, dust, smoke
• Pollution
• Reduced blinking
• Eye fatigue and discomfort

It does NOT treat infection or glaucoma—only lubrication.

Direction of Use

• Instill 1–2 drops in each eye
• Use as often as needed (multiple times daily is allowed)
• Wash hands before use
• Avoid touching dropper tip to eye or surfaces
• Blink after instilling drops to spread evenly
• Can usually be used with contact lenses (depending on variant—check label)

Side Effects

Common:

• Temporary blurred vision
• Mild stinging or irritation on instillation
• Watery eyes

Rare:

• Eye redness or worsening irritation
• Allergic reaction (itching, swelling, discomfort)

Warnings

• Do not use if solution becomes:
• Cloudy
• Discoloured
• Contaminated
• Stop use if irritation worsens
• Do not touch dropper tip to eye (infection risk)
• Do not share the bottle
• Seek advice if symptoms persist beyond a few days or worsen

Interactions

• Very few clinically significant interactions
• If using other eye drops:
• Wait 5–10 minutes between products
• Use medicated drops first, lubricants last (general rule)

Caution

• Overuse is generally safe, but:
• Preservatives (if present) may irritate very sensitive eyes with frequent use
• May temporarily blur vision → avoid driving immediately after instillation
• If dry eye is chronic, underlying causes (e.g., meibomian gland dysfunction) may need treatment, not just lubricants
• Contact lens users should confirm compatibility with their specific Optrex variant
