Basic principles of progressive lenses

The surface of the progressive slice is divided into five regions. There are far, middle, and near optical areas. They are respectively corresponding to see distant objects, middle distance objects in the near distance objects. One pair of glasses is multi-purpose. In appearance, it is not very different from regular lenses. There is no clear dividing line. Distal use area: The area above the progressive slice is the distal use area, which is used to correct the distal refractive error. Proximity area: from the matching lens cross down, the refractive power of the lens continuously increases the positive degree, which is used to see close objects. Gradient area: The channel connecting the far and near areas. It is an area of regular change from top to bottom, used for transitioning and seeing objects at intermediate distances. The length of the gradient is very important for the wearer's adaptation. The rate at which the degree of gradient changes is called gradient. The gradient can be uniform or variable. Peripheral area: Changes in the surface curvature of the lens will lead to aberrations in the peripheral areas on both sides of the lens, mainly astigmatism and prism effect, which will interfere with a vision to a certain extent, resulting in blurred vision or distortion. And it will affect the wearer's adaptation to the progressive lens.


What to consider when buying eyeglasses?

The size of the frame should match the pupil distance so that the edge thickness of the lens is thinner and more comfortable to wear. The size should be proportional to the size of the face. The upper edge should not be higher than the eyebrow and the eyebrow should not be visible in the lenses. The shape of the frame should match the shape of the face and skin tone to meet aesthetic requirements. The rectangular face should choose a circular arc or arc transition frame. An inverted triangle face shape should choose one with a lower wide edge.



How polarized glasses can help you drive

The most important thing about polarized sunglasses is that they can be a good helper when you drive. When sunlight hits your eyes at an awkward angle, these sunglasses will save your life and save you from potential accidents. Polarized glasses can filter out the sunlight reflected from objects such as roads, snow, water, and other objects. It helps to neutralize the effects of reflected sunlight. Polarized sunglasses bring you an incredibly safe driving experience, with almost no interference and no harm to your eyes.

At night, glare and embarrassing lights are everywhere on the road, especially because random drivers come from the opposite side. Some of these driving high beams may disrupt your vision and cause potential accidents. Polarized sunglasses help reduce glare and save your life. Polarized lenses hardly reflect.


Eyewear stores are close to consumers.

Location is a very critical factor. A reason why customers can walk into your store is that if it is convenient to go to your store. If there are two stores of the same size, your store is in front of the school gate and the other one is 500 meters away from the school, then your store will definitely attract more customers than the one 500 meters away.

How do bifocal reading glasses work?

Bifocal reading glasses have two different lenses on the same lens. The top of the lens is your normal distance prescription, while the bottom is for close-up viewings, like reading. The two lenses allow you to alternate between them by moving your eyes up and down as needed. A bifocal lens is a type of lens that has two different areas of vision: one for close range and one for long-range. Typically, the upper section covers remote vision and the lower section covers reading. With a traditional bifocal lens, you can see the difference between the two lenses because the lower curve is a little different.
