Both eyes can see comfortably through both lenses with having to squint one eye to see. Bird watching binoculars are one of the critical pieces of equipment bird watchers carry.
The result is appreciable for many people considering the easier mobility and simpler operation of the binocular equipment. The power of the optics is expressed as two numbers, such as 7 x 35. A lot of binoculars are ruined when dropped accidentally.
It is a real treat for kids to go on nature walks or hikes with their parents, however we all remember how heavy the binoculars were for us as kids, right. A simple coating was devised to prevent this, by allowing more light to pass through the lens, and less to be reflected back.
How well your binoculars will serve you in low light conditions is described as twilight performance. If your application is bird watching, theater or sporting events, a low powered binocular will suffice in most cases. You want to have lightweight handling which is also available with this price.
Next time you travel, bring your binoculars, they will not add measurable weight to your luggage. Like wine, you can go overboard on them, but don t need to.
