Final answer:
Snails have limited visual capabilities with eyes on the ends of their eyestalks, allowing them to detect light and movement but not detailed forms. They rely more on their sense of touch and smell and can see objects clearly only when close to them.
Step-by-step explanation:
The visual capabilities of a snail are quite limited when compared to those of humans and many other animals. Snails have rudimentary eyes at the ends of their eyestalks which are capable of detecting light and shadow but not forms and details. The snail's eyes can detect movement and some variations in light intensity, which helps them navigate their environment and find food or shelter.
While it is difficult to precisely quantify how far a snail can see in human measurements, their vision is best suited for sensing changes in light within a few inches to a foot. Most snails rely more on their sense of touch and smell to understand their surroundings rather than their sight. Given that they have the normal 8.00% ability to accommodate, a snail's closest clear vision range is limited and generally they can see objects clearly only when they are very close to them.
Thus, a snail does not have the capacity for long-range vision, and its world is largely perceived through immediate sensory interactions with the objects it encounters, like leaves, stones, and other elements in its path.
