Are there any non-prescription spectacles to see an object in long distance?

Possibly. If you are farsighted, sometimes the drugstore glasses that people use for reading can help your distance vision. If you are nearsighted they will just make it worse.
Yes. A few places on the internet sell minus power lenses to help with long distance. It is difficult to select the correct power therefore a refraction with your eye doctor may be the best bet. Over powered lenses can contribute to eyestrain and headache.
