They remain cool and require less battery power to generate light, allowing batteries to last longer, so less time is spent changing batteries, which also cost less to maintain. Lastly, also based on the quality of the LED, some quality LED’s cast a broad, even light over your reading material versus a single “laser beam.” The broad bright white light is very helpful for helping people with low vision remain functional with many reading tasks.

Aspheric meaning

Video magnifiers should only be considered IF your professional grade optical magnifying glass with an LED light, backed up by a lifetime warranty, from a reputable low vision organization is NOT providing sufficient magnification OR width (or Field of View). Suppose your professional-grade optical magnifying glass with an LED light, backed up by a lifetime warranty, from a reputable low vision organization IS providing sufficient magnification AND width (or Field of View).

In addition to reducing spherical aberration, aspheric lenses also correct other image distortions, such as astigmatism. Aspheric lenses have been used for many years to reduce spherical aberration and improve the performance of optical systems, but past high cost made them impossible to be used in real-life applications. Recent manufacturing advances in aspheric grinding and polishing have enabled subaperture polishing and produce high-precision aspheres at affordable costs. A single, more affordable, high-performance aspheric lens can replace multiple spherical lenses resulting in the same or sometimes better performance, leading to lighter weight, more compact, and less complex systems at a cost-effective solution that was not possible years before.

Aspheric lenses are optical components with non-spherical surfaces, unlike traditional spherical lenses. They are crucial in correcting aberrations and enhancing image quality across various optical systems. Here, we delve into the significance of aspheric lenses, their manufacturing processes, and their diverse applications.

The voltage is usually a battery. Of the many benefits of a LED magnifying glass, the top 4 benefits are that LED’s can emit, based on the quality of the LED, a very bright white light vs. a yellow-ish light often found on a traditional incandescent bulb. This white light is very beneficial for illuminating your reading material. Next is that LEDs last approximately 100,000 hours, which is roughly 30-40 years of regular use, a very long time. The third is that LEDs produce or give off very little heat.

As the name suggests, an aspherical lens is a lens with a shape other than that of a regular sphere or cylinder. These lenses, which come in a variety of shapes, are used to correct spherical aberration and enhance image quality. Spherical aberration is a type of defect that occurs when light passes through a spherical surface. Depending on how close to the edge it enters the lens, light focuses at different distances, creating a blurry image. In comparison, aspheric lenses focus light to a single point, regardless of where the light ray enters, to reduce or entirely eliminate blurriness from the image.

Easy to use, intuitive use, and one-touch buttons to activate features. Light, portable, customizable. This is the perfect electronic video magnifier for anyone with low vision and age-related macular degeneration.

Why is a handheld magnifying glass with a light important? Have you ever been in a dark room without any light, and it was so dark that you could not see your hand in front of your face?

Have you ever taken a piece of reading material and walked over to the window where bright sunlight makes it easier to read? Most of us do that instinctively. If you have this instinct, you also intuitively get that light is an essential ingredient to see.

An aspheric lens can correct aberrations that would take multiple spherical lenses to correct. This capability means that a single aspheric lens can replace a complicated multi-lens system, leading to smaller, lighter, more efficient and less expensive assemblies.

Even if your vision is 20/20, your eyes need light to see. The same dynamic is playing out with people with low vision when they use a handheld magnifying glass. Light is critical for your eyes to work and see, and light is one of the things most people with low vision take for granted and overlook. Believe it or not, some people simply eliminate the need to use a magnifying glass by adding strong task light.

Aspheric lenses allow optical engineers to increase the numeric aperture size of a lens without reducing image quality, which is perfect for applications that require high light throughput.

The first thing to keep in mind is to ensure that you incorporate a very bright white light. Many people overlook lighting, and when good lighting is used, many have eliminated the need for a magnifier for reading. Believe it or not. “Make it Bigger!” This should be proclaimed from the mountain tops.

If you need to make your print bigger for reading, Step #1 is to use a professional-grade optical magnifying glass with an LED light, backed up by a lifetime warranty, from a reputable low vision organization.

For people with macular degeneration or any type of vision loss, why is it essential to make sure that you are buying a professional-grade magnifying glass?

The main reason is that in the end, as with most things in life, you get what you pay for. There are many different types of magnifying glasses made for a wide variety of audiences and by an unlimited amount of suppliers. The unlimited magnifying glass options are so confusing that often many simply blindly purchase the least expensive magnifier on Amazon, not knowing why other than the luring price.

Video magnification provides the benefit of much more magnification and much more width (or Field of View). There are both small portable video magnifiers and larger non-portable video magnifiers.

At some point, making the image bigger is too big for the lens or monitor. If that is the case, then video magnification is the solution for maintaining functional independence. So, do you need a magnifying glass for reading? Only you can ultimately answer that question. Most people with low vision need Step #1. Consider starting with Step #1; if needed, you now know Steps #2 and #3. We are here to assist along the way.

All in all, you want to ensure both the magnification AND width (or Field of View) of your magnifying glass are sufficient for you so you are not frustrated. Often people get frustrated using a magnifying glass for hobbies because the magnifying glass Does NOT provide either magnification OR width (or Field of View).

Data is important for you to make a decision right now. The larger non-portable video magnifiers are used for productivity tasks, like voluminous reading and writing sessions, hair and make-up, distance viewing, substantial crafts, hobbies, etc. The bottom line is that we all need some type of magnification at some point in time, even when we were a child magnifying insects.

Like other kinds of optical lenses, aspheres can be produced in a number of ways. At Shanghai Optics, we use two main methods to produce custom aspheric lenses: molding and traditional polishing with the state-of-the-art manufacturing and metrology equipment. To mass produce aspheric lenses that require a lower level of precision, we use lens molding. In this method, we pour the heated lens material into custom molds, where they firm up and take their final shape. To ensure success, we make moldable aspheric lenses out of materials with low transformation temperatures, such as acrylic, plastic, BK-7, B270 and Pyrex. Molded aspheric lenses are the most cost-effective type of asphere. For large silicon aspheric lenses that require a higher level of precision, we turn to a traditional polishing method. With high-speed polishing equipment, we shape and refine precision aspheric lenses quickly while adhering to exact specifications. S.O. can manufacture lenses with best-fit-sphere deviation between a few millimeters and a few waves. Though the manufacturing process you choose will depend on your project requirements and the volume of lenses you require, you’ll find that our molded and polished lenses meet the highest expectations. Our production staff follows ISO 9001 standards and uses cutting-edge metrology equipment to take accurate and repeatable testing measurements.
