Dry eyes occur when the eyes do not produce enough tears or when the tears evaporate too quickly. This condition can lead to discomfort, a gritty sensation, and redness. Factors contributing to dry eyes include prolonged screen time, environmental conditions, and certain medications. Treatment for dry eyes often involves using artificial tears or lubricating eye drops to provide relief. In some cases, lifestyle changes, such as taking breaks during screen time or using a humidifier, can help. If symptoms persist, consulting an eye care professional is recommended for further evaluation and management.
