A major loss of air conditioning can indeed increase the risk of certain eye conditions such as dry eye syndrome, fungal infections, and corneal ulcers. Here's how:

  1. Dry Eye Syndrome: When the air conditioning is too strong, it can cause the air to become dry, leading to a decrease in humidity levels. This can cause tears to evaporate too quickly, leading to dry eye syndrome. The symptoms of dry eye syndrome include dryness, burning, itching, and redness of the eyes.

  2. Fungal Infections: A poorly maintained air conditioning unit can be a breeding ground for fungal spores, which can enter the eyes and cause an infection. Fungal eye infections can cause symptoms such as redness, pain, discharge, and blurred vision.

  3. Corneal Ulcers: Corneal ulcers are open sores that develop on the cornea of the eye. They can be caused by bacteria, viruses, or fungi, and can lead to vision loss if left untreated. Air conditioning can contribute to the development of corneal ulcers by causing dryness and irritation of the eyes.

To prevent these eye conditions, it's important to maintain a comfortable temperature and humidity level in your living or workspace. Additionally, it's important to maintain proper hygiene and cleanliness of the air conditioning unit to prevent the growth of harmful microorganisms. If you experience any symptoms of eye discomfort, see an eye doctor for an evaluation and appropriate treatment.
