Sleep and Dry Eye

Dry Eye Syndrome is caused by many different factors. Even how you sleep can worsen the symptoms of dry eye according to a recent clinical study. Aside from how you sleep, how well you sleep can also worsen dry eye symptoms. A clinical study involving 672 participants between the ages of 26-64 years found that poor sleep quality is associated with worse dry eye symptoms.

Many different factors can affect quality of sleep including too much light from LED bulbs, fluorescent bulbs and digital devices. Lighting from those types of “energy-efficient” bulbs affect sleep by disturbing your melatonin levels. If you live in an environment that uses energy-efficient lighting or you use a digital device for more than two hours per day, then wearing glasses that provide adequate protection is recommended. A recently conducted clinical study showed that wearing glasses that protect against that type of lighting REDUCES the symptoms of DRY EYE, STICKY EYES, GRITTINESS, and EYESTRAIN. Other studies also indicate that wearing glasses that protect against that type of light also REDUCES the DISTURBANCE OF THE WAKE-SLEEP CYCLE.

However, not all glasses that are labeled as protective will protect against all of those issues. Some glasses, even ones that are touted as protective against that type of light, do not protect against the entire spectrum of light that affects sleep and dry eye symptoms. If you have dry eye symptoms and you also experience poor sleep, then using the most complete light protection at night may be helpful.
