What is a good progressive lens?

No matter how close the objects you see, the lenses are guaranteed to give you a clear view. Whether it's working with a computer, using a smartphone or tablet screen, or simply reading the newspaper, it's all about bringing a comfortable feeling for you. At the same time, the lenses have greater contrast and clarity. The lenses have been tested and approved by the wearer to ensure customer satisfaction, including quick and easy adaptation.



What are browline frames?

The name browline comes from the design of the frame. The upper part of the frame is thicker than the lower part so that the wearer's natural eyebrow line can be noticed. The top is usually made of acetate or plastic, and the bottom of the lens is wrapped with a thinner wireframe. Later, the browline frames have also been modified to meet the needs of more customers. Some browline frames use nylon wire instead of metal wire in the lower part, while the browline frames with metal wire are more durable and stable. If people with high myopia want to have a pair of half-rim glasses, browline frames are a good choice.


The advantages of contact lenses

Contact lenses are worn directly over the eye. Contact lenses are tightly attached to the surface of the eye and can always follow the eye, so you can maintain the same open field of vision like a normal person. You can participate in sports and outdoor activities without worrying about your glasses falling off or breaking. You can even use colored contact lenses to change the color of your eyes. Some girls, in particular, can make their eyes look bigger and more beautiful with the help of various color contacts.



About Polarized Sunglasses

Polarized sunglasses only absorb the reflected light of the object itself, presenting what is being seen, making the field of view clearer and thus reducing eye strain. In addition, the light through a bumpy road, water, and other places also can produce irregular diffuse light. The polarized lens can be this kind of optical filter, only absorbing the reflection of the object itself. Because of its high-efficiency filter layer, the UV blocking rate of the polarized sunglasses is 99%, which can effectively reduce UV damage to the eyes. And if you are driving, fishing, traveling, skiing, it is recommended to choose more powerful polarized sunglasses.


The inadequacies of bifocals

The field of vision is smaller than that of the single vision lens, especially for the close view. For example, reading and reading newspapers need to make it coordinated with the head movement, there are optical defects of image jump and image displacement. There is a boundary, and it is easy to be seen that wearing a bifocal lens exposes age. Bifocals clearly demarcate the near and far regions, affecting appearance and vision. And when far view and close view change, the objects will jump. Because most myopic patients have a lag in the adjustment response, wearing bifocal lenses not only does not delay the development of myopia but has side effects. Therefore, bifocals are not suitable for teenagers to control myopia, and only a few special patients need to wear bifocals.

What is the bifocal lens?

Bifocal reading glasses are characterized by distance vision correction in the upper part of the lens and near vision correction at the bottom. If you need help with both, that's great. This lens is designed to facilitate the working of reading glasses and standard prescription glasses, all in one frame. Glasses are recommended when you are diagnosed with presbyopia, and bifocals are usually the first choice. But for intermediate vision, bifocals are difficult because they're not close enough for the reading part of the lens, and they're not far enough away for the distance part of the lens. Bifocal sunglasses have no magnification at the top, and the reading ability is at the bottom of the lens. Bifocal reading glasses can be found anywhere reading glasses are sold, but they can be harder to find than full magnifying lenses.
