We didn’t create form-based coding, but we’ve been trailblazers in the field for more than 20 years. We are experts in understanding how the form of buildings will shape community spaces, and we can simplify the process of introducing form-based codes with a predictable build-out. We know quality should be something you can see (with or without your readers on).
Who Are Designer Optics Eyeglasses Right For?
Spherical aberration (SA) is perhaps the simplest to understand, since it depends only on distance from the optical axis. Most optical surfaces are sections of spheres, since these are the easiest surface shapes to make . For a simple spherical-surface lens or mirror, rays at different heights on the surface are not bent to the same degree, so they focus at slightly different distances along the axis; this is SA. With simple lenses, you can reduce SA by choosing the right lens form ("lens bending", as we say in the trade).
What do Optical Engineers do?
Although we usually think of visible light when we say "optics," visible light is simply a narrow band of the electromagnetic spectrum, which ranges in wavelength from very short (e.g., X-rays) to medium (e.g., green light) to very long. Optics can help us with these other wavelength regions, but most of our discussion here will focus on the important and familiar visible spectrum (i.e., the colors of the rainbow, from violet light with wavelengths near 400 nm [nanometer, one-billionth of a meter] to red light near 700 nm). For comparison, X-ray wavelengths are in the nanometer range, while radio waves range from centimeters to meters in wavelength.

One interesting fact about light is that it acts sometimes like a wave, other times more like a stream of very fast particles or quanta called photons. This wave/particle duality remains one of the mysteries of nature, but in practice we emphasize and use whichever aspect makes our calculations easier! In lasers and detectors, quantum effects are especially important, but in optical design, wave or "physical" optics tends to dominate. The Knoxville City Council recently adopted Middle Housing Zoning standards informed by Opticos’ Missing Middle Housing Scan. The Council’s aim is to expand housing options while preserving neighborhood character.
Groundwork Housing Summit Keynote, Daniel Parolek
Collaboration between Opticos and the City of Sacramento is underway to enable Missing Middle Housing citywide as part of a broader effort to increase the supply of lower-cost, attainable housing. The City of Sacramento took a monumental step forward when the City Council adopted the 2040 General Plan on February 27, 2024. It’s in every decision we make – from our colorful frames to all the ways we give back. We’re committed to glasses that are more than half full, they’re fully amazing. Because we truly believe the future can be bigger, bolder and better than ever.
In particular, if you know of educational optics resources on the internet, please let us know (send e-mail to ). That, of course, is small potatoes compared with what Kushner did next. Kushner cozied up to Prince Mohammed during the Trump presidency and it seems the relationship paid off.
Need Help With Your Optical Engineering Challenges?
Opticos principal Daniel Parolek inspired a new movement for housing choice in 2010 when he introduced the concept of the “missing middle” in American housing. Today, Opticos creates innovative architectural designs to help build walkable communities with unique, diverse housing choices that are attainable for all. Over my 10+ years testing optics, some things consistently rise to the top in terms of quality construction and durability. And given the manufacturing standards of premier fashion houses, I was expecting good things from Designer Optics‘ wares. Since smaller is better, your goal is to find the lowest possible point on this map -- the Death Valley of Error Function Land (EFL).
In the last decade testing optics for over 3000 customers, I‘ve seen interest in premium labels continue to grow. But are Designer Optics products worth their usually high costs, even at sale prices? This extensive review will share my first-hand experiences and recommendations after evaluating multiple pairs. There are some excellent sources of information about optics, most of them on paper in books and periodicals. This list is just a starting point -- we will add to it over time and we welcome suggestions.
Urban Design and Planning
On the whole, buyers feel delighted at the unexpected intersection between fashion indulgence and practicality they discovered through Designer Optics. While less cost-effective than Target or Zenni Optical, you certainly score major price cuts on coveted brands through Designer Optics no other optical company offers. Well, right -- this is one type of lens, and the most common type at that (most eyeglass and contact lenses are this type).
Certainly Saudi Arabia must have had some reason to trust Kushner, who doesn’t have much of a track record in private equity. The only Trump who seems to be taking it uncharacteristically easy right now is Ivanka. The former first daughter has kept a low profile since leaving the White House and seems to permanently be on vacation. Ivanka and her husband, Jared Kushner, worked very hard as unelected advisers to the president during Trump’s term – evidenced by the fact that they reported up to $640m in outside income while serving in the White House. Over the years the Trump family has made it very clear that, as long as a payday is involved, optics aren’t important. Every single one of them seems to have some sort of grift going at all times.
Maybe not, but the point is, with local optimization, your choice of starting point is very important. (In our picture, local optimization will NOT get you to the lowest point -- it will roll you into one of the valleys to the right or left of the "You are here" starting point). We believe age is nothing but a magnification number and just because your eyesight is changing, doesn’t mean you have to. You should never have to surrender your style for a moment of clarity - no matter how small the font or the size of your screen. So we aim to reframe the whole conversation about readers and make glasses that you can wear proudly. No need to keep pushing back up nose.😎 Lenses distributed weight evenly without uncomfortable pressure points behind ears.😎 Sophisticated styling elevated casual and business wear outfits effortlessly.
Remember that the goal of optimization is to take a starting lens of some sort and change it to improve its performance (the starting lens should have a suitable number of optical surfaces of suitable types, since optimization can change only the values of the parameters, not the number or types of surfaces). Since optics is very precise (distances of micrometers can make a big difference), we need to closely determine the values of all our variables at each step of the optimization. If you have a lens model, an error function is something that correlates with its image performance, like spot size or RMS wavefront error -- smaller is better. As variables are changed, the lens changes, ray trace values change, and the error function takes on new values.
For help choosing which optical design software is best for your application, visit our Choosing An Optical Design Software Solution page. These are the subjects of this "gentle introduction." Our hope is to give you a flavor of what is involved, and to point you to other sources in case you want to learn more. Our business is based largely on what is commonly called "lens design" or (more correctly) optical design.
If you could plot these out, you would create a map of the hills and valleys of error function space (in anywhere from one to 99 dimensions or more, depending on your variables). In the admittedly silly sketch above, vertical distance represents the error function value (lower is better), and horizontal position represents ONE of the variables in the lens (for example, it could be the curvature of the front surface). Under the right circumstances, we can further simplify our calculations with the additional concept of light rays. Rather than thinking about waves propagating through space, we think about lines that are normal to the waves (i.e., traveling in the direction of the advancing wave front), and we call these lines light rays or simply rays.
This article is for the general reader who may be curious about this area of applied optics. Aberration can be expressed in various ways, most of which start out by tracing a number of rays through the lens to see where they go. The ray distribution can be plotted as a scatter plot (we call this a spot diagram), or cross-sections of ray position data can be plotted (ray trace or "rim ray" curves). To those trained in the art, the shapes and sizes of the resulting patterns can tell things about the amount and forms of aberrations that are present, and with this information, you can plan to correct or reduce the aberrations in various ways.
