Use in the affected eye(s) as directed.

Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over the eye and place 1 drop into the pouch. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of the eye near the nose and apply gentle pressure.

Repeat these steps if your dose is for more than 1 drop and for the other eye if so directed.


Eye redness or hyperemia is a common complaint in ophthalmic clinics. It is often associated with other symptoms such as:

  • Eye pain, burning or itching,
  • Eyelid edema, blurred vision,
  • Watery eyes or stringy secretions
  • The gritty feeling inside the eyes.

The causes of eye redness are multiple. Your doctor needs to thoroughly exam the signs and symptoms to decide the causative agent. If an infection is suspected, samples may be taken for laboratory analysis. The common causes behind red eyes are:

  • Allergic conjunctivitis
  • Dry eyes
  • Bacterial or viral infections
  • Irritants such as chemicals, shampoos, dust, or pollutants
  • Fungi infection

Red-eye is a symptom of conjunctival inflammation. The conjunctiva is the most superficial layer of the front eyeball. It is thin and covers the white of the eyeball and the insides of the eyelids.

The conjunctiva provides protection and support to the eye structures. It prevents foreign objects and microbes from entering the deep eyeball layers. It also keeps the eye hydrated.

The conjunctiva has a rich blood supply, and it is ordinarily transparent. When inflamed, the blood vessels enlarge, causing hyperemia and redness.

Naphazoline binds to the alpha receptors on the blood vessel’s surface to cause contraction and narrowing of the lumen. Naphazoline binds to both alpha one and alpha two receptors. Unlike agents that only bind to alpha one receptor, Naphazoline does not lose its effectiveness over long-term use.

Boric acid is toxic when ingested, but it has been used for generations as an eyewash. It eases irritated and dry eyes. Additionally, it clears the eyes of foreign objects or dust.

Boric acid has three medicinal properties that make it the perfect treatment for red, irritated eyes:

  • Boric acid solution is isotonic to the body fluids. When applied as an eyedrop, it neither absorbs water from the tissues nor diffuses into the tissues. A physical quality that makes it ideal for irrigation Because it will not disturb the chemical composition of the eye.
  • Boric acid works as a buffer, protecting the eyes from environmental acids or alkali. It balances the normal ph inside the eye even if exposure to acidic or alkaline chemicals occurs.
  • Boric acid has mild antiseptic properties. Sustained application of boric acid inhibits bacterial or viral contamination and growth.
