What Are AR Glasses?

AR glasses are a new type of smart eyewear that can enhance your vision with digital data. They’re similar to VR headsets, but instead of putting you into a virtual world, they layer computer-generated images on top of your existing environment.

They can be used for a wide range of applications, including shopping and gaming. They can also enhance navigation and help improve productivity.

Anti-Reflective Coating

Anti-reflective coating, also referred to as AR, is a type of lens coating that reduces the amount of light that reflects from your lenses. This helps you to see better and more clearly by reducing the amount of glare that is visible through your lenses, especially when it comes to things like a digital screen or a camera flash.

This coating is usually applied to the front and back of the lens, although some glasses may come with a factory-applied AR coating on both surfaces. The coating is fused to the lens matrix, preventing it from peeling, scratching, or spotting over time.

The main advantage of the AR coating is that it allows more of your environment’s natural light to reach your eyes. This can help you to focus better and see more clearly, even when wearing sunglasses. It can also prevent you from seeing a “halo” of light around lamps or other lighting sources, so it’s a great option for those who wear glasses when they’re out and about at night.

Another advantage is that this coating can help you to avoid eye strain, as it reduces the amount of reflections in your ar glasses lenses. This can help to optimize your vision and make it easier for your eyes to focus on small patterns and letters, which can be beneficial for those who wear glasses and have eye problems like cataracts or glaucoma.

There are a number of different types of AR coatings that you can choose from. Some are simple, while others are more complex.

One of the more common types of AR coatings is called a graded-index (GRIN) anti-reflective coating, which is designed to curtail reflection for a broad band of wavelengths and incidence angles. These coatings can be made of a single transparent material with a refractive index that varies with thickness, or they can be produced by incorporating microlayers in the design of the coating.

An additional type of AR coating is an absorbing ARC, which uses special optical properties to produce a thin film that has lower reflectivity than air at non-normal incidence angles. Absorbing ARCs are often more inexpensive or more easily produced than standard non-absorbing ARCs, and can be useful for situations where high transmission is not important, but low reflectivity is needed.

Optical Grade Lenses

To create comfortable, lightweight AR glasses that look natural and have a large field of view, smart technology must be embedded into the lenses. These can include displays, filters, active dimming, and other features. The lenses must also be thin and light enough to fold and carry with ease without sacrificing performance or comfort.

For example, researchers at the University of Utah developed glasses with flexible lenses and piezoelectric pistons that can be adjusted to focus on a user’s specific vision. The frames can be customized to a user’s prescription and distance to the desired focal point, using a microcontroller in one stem of the frame that receives the prescription information and uses an algorithm to change the voltage on the pistons.

Similarly, Columbia Engineering has invented a flat optical device that can focus only narrowband colors of light, while remaining transparent to nonselected light over most of the spectrum. This technology is being tested in a pair of AR glasses that will let users experience immersive virtual environments and augmented reality.

A key factor in making this technology work is the glasses’ ability to be worn for long periods of time. This is especially important for people who have trouble keeping their eyes open for extended periods of time, or those who suffer from vision issues such as myopia or hyperopia.

Another solution is to use reflective waveguides instead of traditional LCDs or OLEDs, which can be bonded directly to the lenses. These reflectors are highly efficient and can deliver 2K x 2K resolution, full color and over 4,000 nits per watt of illumination in a small form factor that is also outdoor-compatible.

These reflective waveguides can be fabricated at scale and can overcome the three biggest challenges that are holding back the adoption of AR glasses: design, cost, and optical performance. They can be used for a wide variety of use cases, including outdoor, military, medical, and consumer products.

Lumus’ Z-Lens waveguide architecture paves the way for smaller, feature-packed AR glasses with Rx compatibility. It maintains the high image quality and high luminance efficiency advantages of its Maximus 2D waveguide architecture while shrinking the projector module by more than 50%. It can deliver a 50deg field of view, with over 4,000 nits per watt illumination in a small form factor that is outdoor-compatible.

Optical Grade Frames

Optical grade frames hold prescription lenses in the proper position to provide optimal vision. They can also be a fun fashion statement and are an important part of any eyewear wearer’s outfit.

Choosing the right frames and lenses is an individual choice that should be guided by your personal preferences, medical needs and lifestyle activities. At Eyeland Family Optical in Creswell, our experienced team is here to help you make the best selections for your unique face shape and needs.

First and foremost, we recommend getting a thorough eye exam to ensure your eyes are healthy and functioning properly. We will check for any underlying medical conditions that may be causing blurred vision, irritated eyes, eye allergies or other problems with your eyesight.

Our team of certified opticians can test your eyes to determine your prescription and fit you with the most appropriate glasses for your specific visual requirements. We will also discuss the different types of lenses available and which one will be most effective for your eyesight type and activity level.

We also carry a wide selection of frame materials, shapes, colors and styles to meet your needs. These include plastic, acetate, titanium, TR90 and a combination of these materials.

The most impressive frames are usually made from a durable material such as cellulose ar glasses acetate, which retains its looks and is very lightweight. Some materials, such as acetate, are even more environmentally friendly than the typical petroleum-based plastics used in most mass-produced glasses.

As a result, we are pleased to offer a wide variety of optical grade frames in a range of styles, sizes, and colors at an affordable price. Contact us today to learn more about our products or schedule an appointment with our doctors.

Sensors

The sensors on ar glasses allow them to detect a variety of things around you, such as lighting, distance, and even your own movement. This is called Simultaneous Localization and Mapping (SLAM). These sensors are important for the accuracy of the display because they can adjust the screen based on how you move your head.

Some of the most commonly used AR glasses include Google Glass and Microsoft’s HoloLens. They both use stereoscopic 3D displays to overlay virtual objects onto the real world.

However, both devices have some drawbacks. The main problem is that they can strain your eyes if you wear them for long periods of time.

One solution is a new type of augmented reality technology called retinal projection. The technology is similar to the way that TVs project images onto your retinas, avoiding the need for glasses with displays that also double as prescription lenses.

This technology also avoids some of the pitfalls that VR and AR users have faced, such as headaches and eye strain. Apple recently filed a patent application for a pair of glasses that use a beam to project a display less than an inch in front of the user’s eyes.

It could be useful for AR-enabled games that are triggered by a user’s movements, such as racing or driving. The beam would also ensure that the image always stays in focus, avoiding the need for prescription lenses.

Another sensor on ar glasses is a gyroscope, which measures your movement and helps to keep them stable. This is especially important for VR and AR, as a comfortable experience is essential.

In addition, AR glasses often have a camera and other hardware that can help with the computer vision process. The device can also track the position of your face, and its gyroscope and motion sensors can recognize the movements of your eyes and facial muscles.

Some ar glasses are designed specifically for enterprise use, like the Xvisio SeerLens(tm) One from Xvisio Technology and STMicroelectronics. These glasses feature Xvisio’s industry-leading vSLAM engine and ST’s state-of-the-art image sensors and IMU technologies. This model has a USB-tethered connection and can be used with off-the-shelf mobile phones and PCs.
