How to irrigate the eye using seawater?
The most comfortable and simple way of maintaining proper eye hygiene is by using Quinton Medical Eye Health’s ocular spray. Follow these instructions for proper application:
- Remove the transparent cover from the nozzle.
- Hold the bottle in the palm of your hand, placing your index finger on the nozzle.
- Tilt your head and bring the bottle close to your eye, at least a 5 cm distance.
- With your eye closed, press the nozzle for 1 to 2 seconds until the eye and its surrounded parts are completely moistened.
- With your head still tilted, open your eye and blink several times.
How do we neutralize pollutants?
The presence, to a greater or lesser extent, of these latter pollutants is the reason why it is essential that seawater undergo a process of neatralization in total aseptic conditions, regulated by the health authorities such as the European Food Safety Authority (EFSA).
In the case of Quinton Medical products, all our raw material is subjected to double cold microfiltration, following the AQP protocol. This allows us to remove the microbiological load naturally present in seawater, preserving its physicochemical qualities.
Other sterilization systems, such as heat or ultraviolet rays, produce the micro-precipitation of calcium and magnesium salts that are no longer bioavailable and cause the appearance of hydroxyl (OH-) or free radicals, destroying organic matter such as vitamins, amino acids and enzymes. In addition, with microfiltration, we ensure the absence of microplastics (something that heat doesn't eliminate).
Irrigating the eye with seawater: research and studies

According to this study, the application of the Quinton Medical Eye Health isotonic seawater eye spray is significantly more effective in reducing symptoms (such as irritation and inflammation) than treatments using artificial tears in patients with dry eye syndrome.
Quinton Medical Eye Health reduced symptomatology by 68% in patients that were treated, in addition to achieving a feeling of freshness and immediate relief of symptoms and a reduction in mucous secretions after application.
Eye irrigation in the treatment and prevention of dry eye
Dry eye is a condition in which a person's tears aren't of good enough quality to lubricate and nourish the eye. Tears are necessary for maintaining the health of the eye's surface and to provide clear vision. Dry eye is common and often a chronic problem, particularly in elders.
People with dry eye do not produce enough tears or their tears are not of a good enough quality. Symptoms of dry eye include irritated, gritty and/or itchy eyes. Advanced dry eye syndrome can damage the eye's surface and affect vision.
Dry eye treatments aim to restore or maintain the normal quantity of tears in the eye to minimize dryness and related discomfort, as well as to maintain eye health.
For this purpose, eye irrigations using isotonic seawater solution are particularly suitable to relieve the symptoms and prevent possible infections from arising. The key is that it maintains isotonicity with the liquids of the human organism and with the pH of the tears that our glands produce naturally, as it has a slightly lower concentration of salts than tears (14 grams per litre), which produces a sensation of immediate relief.
