Etiology - Dry eye syndrome is caused by a decrease in tear production amount and/or tear production quality. This hamper to tear production is typically due to factors such as aging, vast hormonal changes, medications, and increases in tear evaporation.
Symptoms - Stinging/burning sensation, dryness, redness, visual fatigue, excess tear production (overcompensation for dryness), light sensitvity, and difficulty wearing contacts.
Details - Dry eye syndrome is a pretty simple and self-explanatory disease. It's essentially just a nagging feeling of irritation or discomfort in the eye due to improper tear production.
Treatment - Dry eye syndrome treatment is not a one-size-fits-all approach since finding a solution largely relies on addressing the root cause (which can vary). Common treatment strategies include prescription eye drops, artificial tears, regular application of a warm compress, and lifestyle changes (decreased screen time).
