Feature:

These binoculars are equipped with a unique light sensitive optics system that allows you to get a clear picture and radiant, natural colors without the use of batteries and in low-lit areas.

The binoculars operate best when they are used in an area that has a light source, not it complete darkness. This light source may be the moonlight, camping lights, streetlights, or another distant light.

The rubber covered eyepiece can be twisted up and down for different people adjusting a proper eye relief. The eyeglass wearers can adjust the eye relief through rising eye cups and feel more comfortable.

Attention:

After purchasing the telescope, be sure to pay attention when using it: the storage place must be dry, because the film is easy to fall off, and the prism may become foggy or moldy if it is wet for a long time. 

When using, if you find dirt or marks on the lens, do not wipe it with water! 

The best way to do this is to dab a cotton swab in alcohol or gasoline at home and wipe it gently.
