Before purchasing a telescope it is very important to know what you want and what. Careful consideration needs to be made whether a new birder or one who has spent some time in the field and acquired some expertise.
Modern binoculars come with a variety of coatings to protect the lenses and improve the brightness of the observed image. So having a small and handy binocular that you can always carry with you is ideal. If you are going to use the binoculars yourself go for a higher quality optics which naturally would cost more.
The coating reduces glare and protects your eyes from UV rays, and increases the definition and clarity of an object. In addition to this, the surface of the prism has a special mirror coating to prevent light loss. How well your binoculars will serve you in low light conditions is described as twilight performance.
A field-of-view of 390' indicates that the width of the sight picture is 390 feet at a distance of 1000 yards. Under the right conditions, water drops could form inside the chamber, which could form permanent streaks on the lens when they evaporate. Coated lens will improve the binoculars contrast and image quality.
Treat your kids to a pair of inexpensive binoculars to explore the natural world around them. Binoculars allow you to take in all of the details from a distance.
