Optrex Rehydrate Dry Eyes Eye Drops

Optrex Rehydrate Dry Eyes Eye Drops is an over-the-counter lubricant eye drop. Its active ingredient is hypromellose, a well-established demulcent that is widely used in artificial tear products. The 10ml bottle is preservative-free and halal-certified, making it suitable for people who prefer to avoid preservative-related irritation with regular use.

This product belongs to the ocular lubricant (artificial tears) class. It can be purchased without a prescription and is generally considered suitable for adults and children who can safely self-administer eye drops, although parents should supervise use in younger children.

Hypromellose is a cellulose-derived polymer that increases the viscosity of the tear film once instilled onto the eye. By thickening the tear layer, it slows drainage of the drop from the ocular surface, extends the time the eye stays lubricated, and helps create a smoother, more stable film over the cornea and conjunctiva. This cushions the eye against friction from blinking and helps protect the surface from further moisture loss, particularly in dry or air-conditioned environments.

Wash your hands thoroughly before use. Tilt your head back or lie down, gently pull down the lower eyelid to form a small pocket, and instil 1 to 2 drops without letting the dropper tip touch the eye, eyelid, or any other surface, to avoid contaminating the bottle. Blink gently to spread the drop across the eye. If you wear contact lenses, remove them before applying the drops and wait at least 15 minutes before reinserting them, unless your eye care professional has advised otherwise. If you are using more than one type of eye drop, space each product at least 5 minutes apart.

The typical adult dose is 1 to 2 drops instilled into each affected eye, 3 to 4 times a day or as needed. There is no fixed maximum number of applications stated by the manufacturer, but if you find you need to use it much more frequently than this, or if there is no improvement after 3 days of regular use, stop self-treating and see a doctor, optometrist, or pharmacist for a proper assessment.

Use Optrex Rehydrate before the expiry date printed on the bottle and outer carton. Because this is a preservative-free formulation, always check the carton for the specific in-use discard period stated by the manufacturer after first opening, and stop using the bottle once that period has passed even if the printed expiry date has not yet been reached.

Store below 25°C in a cool, dry place, away from direct sunlight and out of the reach of children. Keep the bottle tightly closed and upright between uses, and do not use the product if the tamper-evident seal is broken, if the solution looks cloudy or discoloured, or if the bottle has been dropped or damaged.

• Common: mild, brief stinging or a burning sensation immediately after instillation.
• Common: temporary blurred vision for a few seconds after applying the drops.
• Uncommon: eye redness or mild irritation, especially with very frequent use.
• Serious: persistent eye pain, worsening redness, discharge, or a change in vision, which needs prompt medical assessment rather than continued self-treatment.

• Known hypersensitivity to hypromellose or any other ingredient in the formulation.
• Do not use if the tamper-evident seal on the bottle is broken or missing.
• Do not instil while wearing soft contact lenses; remove lenses first and wait at least 15 minutes before reinserting.

• No clinically significant drug or food interactions are known for hypromellose eye drops, as the product acts locally on the surface of the eye and is not absorbed systemically in meaningful amounts.
• If you are using another eye drop or eye ointment at the same time, space the two products at least 5 minutes apart so one does not wash out the other.
• There are no known food or drink restrictions associated with using this product.

• Keep the bottle upright and avoid touching the dropper tip to any surface, including your eye, to prevent contamination.
• Blink a few times after instilling the drop to help spread it evenly across the eye.
• Take short breaks from screens and blink more often during long periods of reading or computer use to reduce how often you need the drops.
• If you wear contact lenses, always remove them before use and wait at least 15 minutes before putting them back in.
• Do not share your eye drop bottle with other people, even family members, to avoid cross-contamination.
• See a doctor or optometrist if dryness persists beyond a few days, or if you notice pain, discharge, or vision changes.

Precautions: This is a lubricant eye drop, not a medicated treatment, and is not a substitute for assessment by an eye care professional if you have an underlying eye condition. Contact lens wearers should remove lenses before use and wait at least 15 minutes before reinserting them. Pregnant and breastfeeding women can generally use this product as it acts locally with minimal systemic absorption, but should check with a pharmacist if unsure. Use in young children should be supervised by an adult.

When to See a Doctor or Pharmacist: Speak to a doctor, optometrist, or pharmacist if symptoms do not improve after 3 days of regular use, if they worsen, or if you experience eye pain, sensitivity to light, discharge, redness that does not settle, or any change in vision, as these need professional assessment.
