The magnification indicates how many times the object is magnified. With a 3x magnification, the object that is 9 meters away appears as if there were only 3 meters away.
Binoculars for opera usually have a 3x to 8x magnification. The typical magnification for opera glasses is 3 times. But there are some binoculars that magnify 8 to 10 times.
The objective lens is the largest lens and is closest to the object. Light rays are collected through the objective lens. The larger the objective lens, the more light can enter, thus providing a higher quality image instead of a dark image. However, as the size of the lens increases, the binocular becomes bulkier. The most common theater glasses have a lens diameter of 25mm.
You can easily find the objective lens diameter by the name of opera glasses. Each theater glass contains a number combination, such as 3x25. The first number always describes the magnification factor and the second value refers to the diameter of the objective lens.
Since you have to carry your opera glasses and hold them steadily to enjoy the show, size and weight are important factors to consider.
Heavy and bulky binoculars can be exhausting and uncomfortable because your arm will get tired soon. The best opera glasses weigh between 140 and 190g and can be held for a few minutes without any problems. Folding opera glasses allow you to insert them into the handbag, which is handy and easy to carry.
There are various accessories for opera glasses. A cleaning cloth for the lenses and a soft case for transporting the theater glass. The soft case can prevent scratching and excessive soiling of the lenses. If you put the opera glasses in bags that contain other items, there are risks of scratches from hard and sharp objects such as keys. So a soft case is recommended for storage and transportation.
To make it easier for you to hold, opera glasses with handles are ideal. You can mount the handle on the edge of a tube of binoculars. And then use one hand to hold it.
Lightweight binoculars come with a neck string so you can simply let them hang down around your neck when not in use. This is very convenient when you don't have a table to put it on. The neck string is either attached in the middle or on the two outer sides of the objective lenses.
Opera glasses are small binoculars. They are intended for slight enlargements at indoor events, like opera and theater. This is why opera glasses are often referred to as theater glasses.
In addition to opera glasses, some binoculars can be used for opera and theater. These binoculars are compact and lightweight but offer a higher magnification of 8x.
Make sure the magnification does not exceed 10x so you can get an ideal view of the stage.
Although common opera glasses only have a 3x magnification, you can identify the facial expressions of the singers in the theater and opera halls, even from the top tier. A higher magnification is not necessary as the stage is not that far away.
However, if you would like to use opera glasses to watch concerts and sporting events, 8x binoculars are more suitable. Since the stadium is much larger than an opera hall, a 3x magnification is not enough.
In conclusion, if you want to use the binocular for opera, concerts, sporting events, and other activities, an 8x binocular would be a great versatile choice. If you only use the binocular for opera and theater, low-power opera glasses should be enough.
Based on their appearance, opera glasses can be divided into two categories: vintage and modern opera glasses.
Since the opera is very classic and elegant, most of the opera glasses are designed with a noble, antique look. The golden paint color is used in all models. The shape of the vintage opera glasses is often ornate and has many curves.
With their elegant appearance, vintage opera glasses fit perfectly into the ambiance of these events.
In contrast, modern opera glasses have very clear and straight lines. Their paint color is usually silver and black. With the minimal design, modern opera glasses are also suited for concerts, sporting events, and other casual events.
Opera glasses are a type of binoculars. So you should be careful to keep the lenses clean. If lenses are dirty, your view is restricted.
To remove small amounts of dirt or oil, you can use a clean microfiber cloth or a cleaning cloth for glasses and wipe the lenses clean.
If your binoculars have stubborn stains, dry cloth is not enough. Moisten this cloth and put a small amount of detergent on it. Gently rub the lenses clean and then wipe with another dry cloth.
When cleaning your opera glasses, do NOT hold them under running water. These models are usually not waterproof. Otherwise, water stains on the inside of the lenses cannot be wiped away.
Opera glasses are usually Galilean in regards to the construction. This means that you have one objective and one eyepiece lens per telescope, which creates an upright and enlarged image.
In prism binoculars, there is an erecting prism between the eyepiece and objective lens, which rotates the objects by 180°. As a result, these binoculars achieve higher magnification than theater glasses.
Yes, you can use opera glasses while wearing glasses. However, the glasses are already 13mm away from your eye. Therefore, the eyepiece lenses must have an eye relief of at least 15mm so that you can look through the binocular with glasses.
There are also opera glasses with diopter adjustment that allows you to look through without glasses and still get a sharp clear image. However, this feature is not so common in opera glasses. You can buy an 8x binocular that comes with a diopter adjustment.
It's often difficult to find opera glasses in local stores near you. However, Opera glasses can be purchased cheaply in online shops. Select the best theater glass you want from the large selection of models from well-known platforms, such as Amazon, eBay, Target, or Walmart.
If you need international shipping, SkyGenius does offer worldwide shipping on all the binoculars. For U.S. customers, there is a 5-7 day free delivery so you can get your binocular in time before the trip to the opera.
