Yes, because they have eyes.

Snakes have poor eyesight, but they make up for it other ways. The Jacobsens gland is one way. This gland is situated in the snakes mouth/theoat and smells for the snake. The snake tongue is generally forked and as the snake flicks the tongue out, the snake tastes the air by the gland. The fork in the tongue gives the thr snake the direction the food is located at. Sort of like the blinker of the car in front of you shows the way it is turning. One side picks up more scent than the other.
Other snakes like pythons, rattlesnakes and adders have heat receptive pits along the mouths and use those to sense the warmth of thier prey. The pythons use stangulation to subdue the prey, the others use fast working venom.
There are some snakes that have large eyeballs and would probably rely on eyesight. These snakes, such as the Green tree snake and Brown tree snake of Australia are usually nocturnal. The Green Tree snake is a frog eater and would have to rely on eye sight to catch a frog. The Brown Tree snake eats small mammals, including bats. The snake would need good night vision to each such food.
Hope this helps.

They have some vision but it's not particularly good. When snakes shed their skins they also lose a layer from the eyes. That makes them blind during part of the shedding process, and they don't have great vision at other times.
The snake's most developed senses are touch and smell. They can sense heat sources and can pick up vibrations from the ground and "hear" that way. They are essentially deaf.

Not the same way that you do. They have eyes, but their eyesight is very poor. Pit vipers sense heat with very sensitive organs in their pits and they "see" the shape of the source of heat. If they are near a small rodent, for example, they will "see" it as a small, reddish rodent shape. They will recognize this as prey. If they are near a large animal or a human being, they will "see" this as a reddish shape in the form of the animal or human being. Because of its size, they will know this is not prey. If they bite, it will be in defense, not because they expect anything to eat.
In addition, snake's tongues are extraordinarily sensitive to any sort of vibration or movement. This is another way that they "see". They sense movement with their tongues and they can glean a lot of information from this movement; distance, direction of movement, etc.

Most of them can, 'cause they have eyes and they require them to hunt and to defend themselves. But some cave snakes and deep-water snakes can't as they don't need to see to eat or do whatever.
