Can I order progressive glasses online?
Glasses belong to the half medical and half business industry, in addition to the price of glasses, frame style, lens quality, there is more need in professional glasses services. The quality will be very different. The refractive index, film layer, light transmittance, and anti-oil resistance of the lenses almost invisible to the naked eye will be very different, so the prices of different brands of glasses are not comparable. There are many considerations when buying progressive glasses online. If the lens is too far away from the eye, people with myopia may not be able to see clearly, and people with hyperopia may have too much diopter. If the distance is too close, the opposite is true. In addition to the accuracy of optometric data, we need to pay attention to the importance of frame to maximize the benefits of the progressive lens.
How do I choose the right glasses frames?
Choosing a frame is largely a matter of personal preference. However, in addition to the style, you need to check the comfort level to see if there are problems like ear clips, nose compression, skin irritation, and so on. Please note that if you are highly short-sighted, try full-frame glasses, because full-frame glasses can hold heavier lenses more reliably. Below are a few easy ways to determine which frames would best flatter your face and show off your style and personality.
Step 1: Identify your face shape. Identifying your face shape is a good place to start when it comes to learning how to select frames which will suit your face shape.
Step 2: Choose colors that complement your skin tone. If you have a cool-colored skin tone, opt for shades of black, gray, and blue. If your skin tone is warm, you would benefit from warm colors, such as tan, pink, and red. As always, when you learn how to select frames, it is easy to know which colors suit your skin.
Step 3: Consider your way of living. When considering how to select frames for your lifestyle, one of the most important things is to make sure the frames fit at the bridge of your nose. This will allow your glasses to stay put better. If you exercise often, comfortable, sturdy frames are a must. If you want to look the part at an important business meeting, you can choose stylish frames with a variety of angles. If you need sunglasses for the beach, go for soft, colorful frames that will complement your relaxed vibe.
Step 4: Flaunt your personality.Frames are the perfect way to show off who you are and your personality. In the process of learning how to select your frames, you cannot forget to choose those that show off your personal style. You can find the perfect shapes, colors, or patterns, but those qualities mean very little if you aren’t comfortable.
How are we nearsighted?
The light from external objects to the eye needs to be refracted by the lens before it can be imaged on the retina. The refractive power of the lens depends on the contraction and relaxation of the ciliary muscle. When we look at close objects, the ciliary muscles contract and the lens becomes thicker. When we look at distant objects, the ciliary muscles relax and the lens becomes thinner. Adjust the focal length of near and far objects so that they will show a clear image on the retina. If you use your eyes too often and the longer the ciliary muscles work continuously, the ciliary muscles will spasm because of too much tension. At this time, the lens cannot be adjusted and thinned. After the light from a distant object is refracted by the lens, the imaging position will fall in front of the retina instead of on the retina. Only a blurred image can be seen, which becomes myopia.
There is another situation. For some people, due to genetic factors, in the process of growth and development, the front and rear wheelbase of the eyeball will gradually become longer. In this way, although the adjustment function of the ciliary muscle and the lens is normal, the image formed will also fall in front of the retina due to the longer the axis distance of the eyeball, which can also cause myopia.
The two causes of myopia are different. Myopia caused by ciliary muscle spasm is called 'pseudo-myopia'. As long as the ciliary muscles are relaxed, myopia can be reversed. Myopia caused by the extension of the wheelbase of the front and back of the eyeball is called 'true myopia', which cannot be reversed and can only be corrected by myopia glasses.
Banton Frameworks
The frames use the best acetate from the best suppliers in Europe. The factory that produces acetate is located in northern Italy. Although there are many other acetate manufacturers, they are arguably the best at what they do. In that industry, their acetate has been used in optical manufacturing since 1849.
What Is Anti-Reflective Coating?
Anti-reflective coating, also known as AR, anti-glare, no-glare, or glare-free coating, can provide benefits to your vision. Anti-reflective coating is added to lenses to reduce glare caused by light hitting the back of the lenses.
Anti-reflective coating is designed to eliminate all reflections from the front and back surfaces of your lenses. Without bothersome reflections, more light is able to pass through your lenses which optimizes your vision. So, anti-reflective lenses can improve vision and make your eyeglasses more visually attractive.
Choose polarizer for fishing
It is best to choose a polarized lens for fishing to filter out the reflections on the water surface. If it is myopia, it is best to choose polarized sunglasses with myopia function according to your own eye conditions. Generally, shops in the glasses city can customize such glasses. There are also special fishing glasses that can eliminate the scaly light on the water surface so that the angler can see the fish hooked.
Disadvantages of polarized sunglasses
Polarized sunglasses have many benefits. However, in some cases, non-polarized lenses are a safer choice. On cloudy days, drivers find that non-polarized sunglasses are better than polarized sunglasses due to the lack of glare and extreme sunlight.
Driving with polarized lenses after snowing can be dangerous for drivers. As the glare of polarized sunglasses is blocked, ice or snow on the road will not be visible. In this case, the advantages of polarized sunglasses will become the disadvantages that may cause accidents.
In addition, when driving along a dark road with few street lights at night, wearing polarized lenses will make it harder to see the road conditions because they dim the available light better than non-polarized glasses. Of course, in low-light conditions, it is best to avoid wearing sunglasses completely while driving.
The most significant disadvantage of polarized sunglasses is that they do not perform well on digital screens and displays. They can cause the images and information on the LCD screen to blur or disappear at certain angles. Don’t wear polarized sunglasses to use these devices while driving.
