Ultraviolet rays (UV) are radiation emitted by the sun. The two main types of UV radiation are UVA and UVB rays. UVA rays are more prevalent and can penetrate deeper into the skin, while UVB rays are more intense but don’t penetrate as deep.

UV sunglasses are sunglasses that block UV rays from reaching your eye. There are different percentages of UV protection. Ideally, it would be best to aim for UV400 sunglasses, which block 100% UV rays. With UV400 protection, you can eliminate UV exposure to your eyes, making sure your eyes are well-protected and not at risk.

Fortunately, UV protection glasses come in a wide range of prices. A good pair of sunglasses can cost from 10$ to 500$. The price range is so wide because many features add to the price. From polarising lenses to the brand name and prescription lenses, many factors play into the final cost of the product.

If you’re wondering whether or not you will regret buying a good pair of sunglasses, the answer is no. You won’t regret protecting your vision and avoiding damage to the eyes.

If you’re worried that buying a good pair of sunnies with excellent protection will cost you a fortune, remember there are many affordable options on the market. Protecting your eyes does not have to be expensive.

UV400 is the most effective blocker of harmful ultraviolet light, as it provides sunglasses with 100% UV protection. However, different percentages of UV protection can be found when buying sunglasses.

For a regular quadrilateral table, you need to know X (the distance from the camera to the table) and Y (half of length of the side facing the camera). Then calculate θ=arctan(y/x), and 2θ < camera HFOV.

Although you should aim to get 100% UV protection, it is with knowing what the other percentages are and what kind of protection they provide.

It is essential for people to protect themselves from the harmful effects of UV rays by wearing protective sunscreen and the correct type of sunglasses.

For an irregular oval table, you need to know X (the distance from the camera to the center point of the table) and Y (semi-major axis). Then calculate θ=arctan(y/x), and 2θ < camera HFOV.

Now we can move on to choosing a suitable FOV for different use cases. Usually, it is related to how big your conference room is and the interior layout.

If your conference room can hold 6-12 people, and most seats are facing the camera, a conference camera with a wider FOV angle such as 120° and even bigger would be better.

On the one hand, exposure to small amounts of UV light is necessary for our bodies to produce vitamin D, which helps strengthen our bones. On the other hand, too much sun exposure can lead to various types of damage to the skin and eyes.

As you can see, at one foot away from the camera, 72.5° FOV gives a vision of 1.4 feet across. It means that at 10 feet you get a vision of 14 feet across. A 72.5° FOV conference camera is a good choice for small conference rooms, with the conference room table at least 3 feet to 4 feet away from the camera.

At 90° FOV, you will get 2 feet of width for every 1 foot of distance from the camera. In this case, 10 feet will provide a vision of 20 feet across. This wider vision is suitable for a majority of conference rooms.

While it is common to grab a pair of sunnies on our way out to the beach, quite often, people don’t know that UV rays can reflect off surfaces such as water, snow and buildings on cloudy days.

The primary function of polarised sunglasses is to reduce light and glare. These lenses are ideal near water and are even considered the best fishing sunglasses.

Field of view (FOV) is the open, observable area a person can see with their naked eyes or via an optical device, such as a camera. In other words, FOV is what you can see without turning your head. It includes what you see ahead of you and your peripheral vision.

Polarised sunglasses reduce glare but do not protect your eyes from UV light. As previously mentioned, polarised lenses have a different purpose than UV400 protection lenses. This means that just getting a pair of polarised sunglasses won’t provide adequate UV protection for your eyes from the sun’s harmful ultraviolet rays.

The short answer is yes; wearing sunglasses with UV400 protection is very much advised by all eyecare specialists. It is the best protection from the sun’s harmful UV rays and provides excellent protection while in the sun.

It is very common for young kids and teenagers to be less aware of the dangers of not protecting the skin and eyes from the sun. While adults, over time, start being more conscious about it. It is crucial to know that UV damage is cumulative; the danger grows the more you spend time in the sunlight during your lifetime.

Children are at a higher risk of UV damage because they tend to spend more time outdoors; not only that, but their eyes are also more susceptible to eye damage. Purchasing a good pair of sunglasses with UV400 protection for your children will help protect their eyes and get them into the habit of protecting their eyes when going out in the sun.

Big conference rooms that can accommodate 12-16 people usually have a setup like this (pictured below). In this case, a 120° FOV may not be necessary. A FOV range of 60° to 90° is enough to get everyone in the camera frame.

It is essential to wear sunglasses as often as possible and not only in the summer, as UV rays are not seasonal but cause harm all year long. Not every pair of sunglasses has UV protection, which means just wearing a generic pair won’t protect your eyes from UV radiation.

Have you ever been puzzled by different FOV angles when choosing the right conference camera for your conference room? Knowing more about FOV is necessary so you don't waste money on the wrong camera. This article will give you a comprehensive introduction to FOV and help you choose the best conference camera.

Now let's look directly at some popular FOV angles for conference cameras. To make it more clear how wide the view will be, we take one foot away from the camera as an example. This way, it's also easier to compare different FOV angles.

Polarised lenses alone, however, do not protect from UV rays. In order to be considered UV protective sunglasses, the polarised lenses must have a UV filter. While not all polarised sunglasses offer UV protection, some can have both.

If you have UV sunglasses and are still determining what kind of protection they offer, you can find that out quickly. The product label should say “100% protection against UV400.” If you’re unsure, you can take your sunglasses to an eyecare professional who can test for UV protection with a photometer.

At 108° FOV, we start to get into cameras which are considered "wide angle". Most huddle room cameras fall into this wide angle category. 108° FOV conference cameras provide 2.8 feet of view at 1 foot distance. This allows you to set up the camera on the long wall.

Prolonged exposure to UV rays could cause short and long-term damage to your eyes. Long-term effects of not wearing UV400 protection could include damage to the retina, cataracts, macular degeneration, or even cancer of the eyes or eyelids.

120° FOV, another common wide angle, is also a fit for huddle spaces. At one foot away, you get a vision of 3.4 feet across. At ten feet from the camera, that means 34 feet. This wide angle can almost get everyone within the camera frame.

If you’re shopping for sunglasses and find yourself confused by complicated words such as UV protection and UV400, all the different percentages of UV protection, don’t panic. We’ll give you all the information required to buy the perfect pair of sunglasses to protect your eyes from the sun’s harmful UV rays.

If your conference room is relatively small, accommodating about 4 to 6 people, and the layout is as the following picture shows, a conference camera with an FOV range of 90° to 120° should be a nice choice. As people are quite close to each other, 90° to 120° FOV conference cameras assure that every one is in the camera frame.

FOV angles can range from 54 degrees to 360 degrees. Bigger angles generally equates to a wider and better vision. But bigger is not always better and necessary. Different conference rooms and scenarios require different cameras, which is why there is so much variance when it comes to FOV.

For conference cameras, it refers to "what you see" through the camera lens. FOV is usually measured in Degrees. The camera is the single starting point, and the view radiates out and gets wider, forming a triangle.

If your conference layout is none of the above types and you want to get down to a specific FOV angle that suits your needs the best, you will have to do some math.

FOV is just one feature you must consider when choosing video conference cameras, but it plays a big role. To determine what FOV angle is the best option, you will have to consider a number of factors, such as the conference table size, room layout, and how far away the table is to the camera. Check out all our conference cameras, and find the perfect one based on FOV.

Because UV rays can damage the eyes, sunglasses are not just an excellent accessory to complete our look; they are crucial for our eye health and can provide UV protection.

At 180° FOV, the camera provides wall to wall coverage. Basically, if you need total video coverage for your conference room, this is the solution you're looking for in cameras.
