Long-term, continual use of contact lenses can cause dry eye.
LASIK and eye surgeries
Many patients experience dry eye after having LASIK or other eye surgeries, such as cataract surgery and lens replacement. Dry eye often goes away within 3 – 6 months after surgery. Sometimes, it lasts longer.
As we grow older, our eyes make fewer tears, which can lead to dry eye. Many women entering menopause experience dry eye due to hormonal changes.
When you are inside a home or an office, too much heat, air conditioning, or other forms of forced air can cause dry eye. Long-term viewing of a computer screen, television, or other digital monitor can also cause your eyes to become dry and tired. When you are outside, increased levels of wind, dust, heat, or smog can irritate your eyes and lead to significant dryness.
Consuming too much alcohol causes the body to become dehydrated. Dehydration from alcohol consumption can cause dry eyes.
Computer Vision Syndrome
American Optometric Association defines this as a group of eye and vision-related problems that result from prolonged computer use. Many individuals experience eye discomfort and vision problems when viewing a computer screen for extended periods. The level of discomfort appears to increase with the amount of computer use. Related symptoms are eyestrain, headaches, blurred vision, dry eyes, and neck and shoulder pain.
