How to Get Used to Progressive Lenses?
In this section, we will show you how to get used to progressive lenses.
- Always wear them. If you try and ease your way in by changing them with your previous glasses, it will take a longer time to adjust.
- You need to find and use new areas in your lenses instead of using whatever space is most convenient.
- Make sure you have a comfortable frame that is adjusted for your face.
- Make sure that the optician fits the lens in the right way with the right equipment.
So, if you have difficulty getting used to the progressive lenses, try the above ways.
Virtual try-on service
Previously, the only way to buy glasses online was by looking at pictures or reviews. But no matter how real the picture is and how good the buyer's feedback is, more than 80% of them will feel inappropriate once they try it on their face. Either the glasses don't match the shape of the face, or the color doesn't match the skin tone, etc.AR glasses virtual try-on can realize glasses online try-on. Using the phone's camera, users can look at the glasses and try them on their faces. They can turn their head in real-time to see how the glasses look at different angles. Online shopping should be tried on before purchase.
Memory titanium series
It has the features of strong elasticity, lightweight, and strong corrosion resistance. Set the essence of memory alloy frame design in one, they can better reflect the wearer's not common demeanor. It is very stylish and avant-garde, and the high-quality color fully highlights the perfect curve of the face.
How Do Progressive Lenses Work?
How do progressive lenses work? You may have this problem. As is well known, when you are over 40, your vision begins to deteriorate and you may suffer the presbyopia condition. So, with the progressive lenses, you can see at all distances with one pair of glasses. They start with your distance prescription at the top of the lens and increase as you move toward the bottom of the lens.
Then you move your head position to allow you to focus through different areas of the lens. Move your head upwards to see something in the distance, hold it straight for intermediate or arm’s length vision and down for near vision for objects that are close up.
In addition, progressive lenses avoid the visual discontinuity or image-jump when your eyes shift from one zone to the other in non-progressive multifocals since there are no distinct lines in progressive lenses.
How to clean the lenses?
When wiping lenses (especially the rimless glasses of resin lens), you must use a special wipe lens or soft handkerchief or paper. When you wipe the lens, you can only wipe it in one direction, not in circles, and don't touch the lens with your fingers. When the lens is stained with dust and sand, it should be washed with water before wiping, otherwise, the lens is likely to be abraded, and the operation should be gentle. At ordinary times, when cleaning, do not exert too much force, pay attention to the grasp of strength. When wiping the lens, it is best to take the side frame with one hand, and the other hand takes the glasses cloth to wipe gently. In order to prevent the lens film layer falls off, do not use alkaline detergent to wipe the lens. Therefore, when bathing or playing at the seaside, glasses should be properly kept to avoid water vapor or seawater caused by corrosion of glasses.
The anti-reflection principle of the anti-reflection film
Anti-reflection Coating, known as anti-reflection membrane, is called anti-reflection coating in English, or AR membrane for short. The basis of anti-reflection is the wave and interference of light. The principle is: Two light waves with the same amplitude and the same wavelength are superimposed, then the light wave amplitude is enhanced. The two wavelengths and amplitudes are the same, but the superposition of wavelengths with different wave paths (similar to dislocation) cancels each other out. Therefore, the anti-reflection film plated on the surface of the lens uses this principle to make the reflected light generated by the front and rear surfaces of the film layer interfere with each other, thus canceling each other and achieving the effect of reducing reflection.
The Disadvantages of Trifocal Glasses
Here, we will show you the disadvantages of trifocal glasses. If you wear the trifocal glasses for the first time, you may spend some time getting used to them. Adjusting to wearing trifocal glasses can take some time. The different fields of vision can make them disorienting at first, but over time you will get used to wearing them and your eyes will naturally move to the prescription they need for the task at hand.
