As the coating applied to your lenses makes smudges more visible, caution is advised in cleaning your new glasses. Using a microfiber cloth is highly recommended, as any other fabric may damage or remove the coating. It’s also recommended to use a spray lens cleaner which will help to lift dust and dirt without scratching the lens. Your glasses should be stored in its protective casing when not in use, to minimise accidental damage to the frame, lenses or coating.

USB Webcams generally have inferior quality to the camera modules that connect to the CSI interface. They can also not be controlled using the raspistill and rasivid commands in the terminal neither by the picamera recording package in Python. Nevertheless, there may be reasons why you want to connect a USB camera to your Raspberry Pi, such as because of the benefit that it is much easier to set up multiple camera’s with a single Raspberry Pi (see below).

You can control a USB webcam both using bash in the terminal and with Python. First plugin the camera and see if the Raspberry Pi recognises it by entering lsusb in the terminal. It should show something like this:

Anti-glare glasses, also known as anti-reflective glasses, are glasses that have had a coating applied to the lens. This coating is composed of many thin layers of materials with an alternating refraction index. These materials even out the refraction of light, reducing reflection, allowing over 99% more light to pass through the lens. Oscar Wylee applies anti-reflective coating via vacuum. This means that there will be no spray marks or uneven surfaces along your glasses. We can add this coating to many different types of lens, such as bifocal or progressive lenses. The lens coating also has a ‘bloom’ colour. This is a faint, lingering colour from the coating itself. The colour itself is most commonly green, but blue or purple coating can be found as well.

In most cases it is best to use a Raspberry Pi camera module. However, to help you with those cases you still want to use a USB webcam, follow the below guide.

anti-reflective coating是什么

As anti-reflective coatings reduce glare and provide enhanced clarity, any fingerprints or dust on the lens surface will appear to be more visible. It is common for people to mention that it is harder to keep their anti-reflective lenses clean. Because of the enhanced clarity the frames provide, the lenses will always be more clear to see. As a result, they will stain with fingerprints and oil smudges more often and more visibly, as well as scratches and damage being more clear in the lenses. At Oscar Wylee, we offer a premium anti-reflective coating that has anti-smudge technology which will combat this disadvantage. Our premium anti-reflective coating also includes scratch and static resistance, a great addition to any pair of optical glasses.The coating is also applied to the outside of the lens. This means extreme temperatures may affect your glasses faster than an uncoated pair.

Blue light is believed to be a sleep disrupting light that emits from many everyday sources of artificial light, such as computer screens or cell phones. Blue light lenses and anti-reflective lenses both reduce the amount of glare that reaches your eyes from all sources of light. However, blue light glasses may be able to block high energy lights from artificial sources that may cause discomfort. Anti-glare (anti-reflective) glasses are more general in their purpose and are made to reduce disruptive reflections and allow more forms of light through your lenses. This includes the high-energy rays emitted by digital screens. Anti-reflective coating will not prevent the possible neurological effects in the way that adult or Kids blue light glasses may be able to. At Oscar Wylee, our blue light filter option includes anti-reflective technology.

Anti-glare (anti-reflective) glasses do not reduce the amount of light that reaches your eyes. In fact, anti-glare (anti-reflective) coating can improve your night vision when you wear it because more light can reach your eyes with no glare blocking your vision. This makes them a recommended choice for a night drive, for leisure or professional work.

Antireflective glasses vs blue light

Having an anti-reflective coating on your glasses will reduce the glare you receive from light and reflective light. This will reduce eye strain, increase vision, and prevent disruptful reflections. Because of the hardening material used in the coating, anti-reflective frames also have scratch-resistant features. The coating can also make you appear better. With the glare reduction, your facial features will be clearer for all to see. The glare blocking will also enhance your frames appearance as it will reduce distracting reflections and make you and your glasses look better in photographs due to reducing the effects of flash.

When any source of light reaches your spectacles, it strikes the back of your lenses and reflects. The reflection from the front of the lens will prevent others from seeing your eyes and the reflection from the back of the lens will be seen by you. This is the reason you may sometimes see your own eyes reflected in a pair of uncoated glasses, and it’s one of the best reasons to use an anti-reflective coating on your glasses.

By preventing the bright reflections and glares of both natural and artificial light, anti-glare (anti-reflective) glasses can provide a greater degree of comfort when you are working with computers. One of the greatest benefits of anti-reflection is when video conferencing. The person viewing your camera image will be able to see through to your eyes without the harsh reflection of your computer screen obstructing their view.
