Refresh Ophthalmic treats symptoms associated with dry eyes, typically tired eyes, soreness, burning or itching. What is dry eye? Normally your eyes are kept moist by the tears that bathe the surface. The action of blinking spreads the tears across the surface of your eyes. Tears contain important substances that lubricate the eyes, prevent infection and slow down evaporation of the tears. Dry eye can occur for several reasons - either because you do not make enough tears or because your tears evaporate too quickly. Symptoms can include irritation, gritty burning, inflamed eyes, resulting in ocular surface damage. Dry eye is one of the most common of all eye conditions. Although it particularly affects older people, it can occur at any age. It is also more common in women How can my eyes be treated? The standard treatment for dry eye is the regular use of artificial tear drops. These drops can be used as often as needed to keep your eyes comfortable. This may vary from a few times a day to every hour. If you need to use drops very frequently, then try to avoid those containing preservatives, which can irritate your eyes.
