How far out to sea can you see a lighthouse?

Assuming a light at a height of 100 feet (30.5 metres), the range to an observer at 15 feet above the horizon will be about 16 nautical miles (29.6 km). This is known as the geographic range of the light.

How Far Can dogs see?

20 feet
Dogs typically have 20/75 vision. What this means is that they must be 20 feet from an object to see it as well as a human standing 75 feet away. Certain breeds have better visual acuity. Labradors, commonly used as seeing-eye dogs, are bred for better eyesight and may have vision that is closer to 20/20.

How far away can you see an airplane?

On a perfectly clear day, you can spot a plane as far as 374km or 232 miles away. But, this figure is entirely theoretical; it assumes that there is no air pollution, no effect of refraction or any other atmospheric effects that can impact visibility.
