Common Causes of Dry Eye Syndrome
Tears inside the eyes serve as a protective coating and keep the eyes moist and wash away any dirt or other particles. Moisture inside the eyes is essential for eye health and not having enough tears will result in dry eyes that causes itchiness and irritation in the eyes.
While most people have had experienced dry eyes without any possible side-effects even in the long-term, dry eye syndrome can further lead to sever eye damage and may even cause blindness. However, early diagnosis and treatment can ease the problems. Here is what you need to know about the common causes of dry eye syndrome.
Dry eye disease is a common factor among many who do not have a physically active lifestyle. While smokers are prone to two-fold increase of dry eyes, those who intake more caffeine throughout the day are also likely to have the condition. Working too long in front of computers can also make the eyes dry and itchy. Other factors that contribute to dry eye disease include working in too hot, too dry and windy environment.
Visual discomfort is common in aged people as there is damage to the ocular sensory apparatus. Most of the people aged over 60 years experience this condition as part of the natural aging process because the glands that produce tears and lipid components are drained as they age and might need medications or artificial tears to cope up with the condition.
Environmental factors including cigarette smoke and other smoke, dust, hair dryers and even air conditioning can affect the eyes. Dust, excess heat and wind are some of the other factors that contribute to dry eye syndrome. So, avoiding dusty and smoky areas can benefit some people as is wearing sunglasses and using humidifiers inside home or office where air cons are used continuously.
Other than the environmental and lifestyle factors, dry eye diseases may also be caused due to hormonal changes in the body. This condition is more common in pregnant women and also during menstruation and menopause as a lot of hormonal changes occur during these times.
Other Causes of Dry Eye Syndrome
Other factors like wearing contact lenses, not blinking enough throughout the day and undergoing certain procedures like laser vision correction can also lead to dry eye disease. While it is normal to blink every twelve seconds, most of the people blink just twice or thrice a minute and it is more common with people spending time on computers. Contact lenses are also a cause as they float on the eye membrane and absorb the tears from the eyes.
