Ответ:

Во-первых, в этой влаге содержатся вещества(хлорид натрия и карбонат натрия и магния) а также полезные бактерии, защищающие глаз от вредных бактерий. Во-вторых, функция влаги - смывать попадающую на глаза пыль, разбавлять вредные газы и пары, соприкасающиеся с глазами.

Why do land-dwelling mammals always have moist eyes?

Land-dwelling mammals, including humans, have moist eyes due to the presence of tears. Tears serve several important functions in maintaining the health and functionality of the eyes. Here are a few reasons why land-dwelling mammals have moist eyes:

1. Lubrication: Tears help to lubricate the eyes, preventing friction between the eyelids and the surface of the eyes. This lubrication allows for smooth blinking and movement of the eyelids over the eyes, reducing discomfort and irritation.

2. Protection: Tears contain enzymes and proteins that help protect the eyes from harmful microorganisms, such as bacteria and viruses. These substances have antimicrobial properties and can help prevent infections.

3. Moisture: The moist environment created by tears helps to keep the surface of the eyes hydrated. This is important for maintaining the health and function of the cornea, which is the clear outer layer of the eye.

4. Clear vision: Tears help to maintain a clear optical surface on the cornea, allowing light to pass through without distortion. This is essential for clear vision.

It's important to note that while tears are present in land-dwelling mammals, the amount and composition of tears may vary between species. For example, some animals may produce more tears than others, depending on their specific needs and environmental conditions.
