Dry eyes is a very common eye condition in Singapore. It occurs when the glands around our eyes produce too little tears on its surface to maintain adequate lubrication and protection. As a result, our eyes are easily subjected to irritants, leading to discomfort.
- Environment.
Pollutants, haze, smoke and the low humidity in air-conditioned rooms often irritate our eyes and cause discomfort.
- Age.
As we grow older, the rate of tear flow and the "effectiveness" of tears decrease. Dry eyes is also more common among postmenopausal female.
- Contact Lens Wear.
Some contact lens material may absorb more moisture from the eyes.
- Visual Tasks.
Eye fatigue from prolonged computer use and staring at TV screens decrease the frequency of blinking which is essential to recoat the surface of the eye with tear film and may lead to dry eyes.
- Other Causes.
Certain medications can cause dry eyes as a side effect. Diseases such as rheumatoid arthritis and Sjogren's syndrome can also cause dry eyes
Common symptoms of dry eyes include one or more of the following:
- Burning and stinging sensation that may be worse in air-conditioned or windy surroundings
- Itching
- Mucous secretions in the eye
- Redness
- Sensitivity to bright light
- Scratchiness, grittiness, or a "foreign body" sensation
- Excessive tearing (this is due to decreased lipids and mucus in the tear film)
- Intermittent blurring of vision, restored by blinking
Artificial Tears and Ointments
In most patients, dry eyes can be relieved through the use of artificial tears. In severe dry eyes, a preservative free ocular lubricant is preferred.These can be used as often as needed.
 Punctal plugging
Our tears drain out of the eye into the nose through a small passage. The opening to this passage can be closed by special plugs so as to trap our tears.

If in doubt, please consult your doctor.
