What are prism glasses?
What is a prism? A prism is a solid object with a cross-section along its entire length. If you cut across something, you'll come across a section that's been cut, and that's a cross-section. The upward section is a prism. If you have double vision, you can add a prism prescription to the lens to form prism glasses. It can help keep your eyes focused and greatly improve your vision. In most glasses, prisms are used primarily to change double vision and are useful for image correction. They can aid in position correction.
How to buy contact lenses online?
Choose the right contact lens for your situation. Base arc and degree need to be added in the hospital or optician shop to determine. Try not to buy according to the framed degree. Some businesses claim to have the lenses having South Korea's silicone hydrogel, with annual throwing. They are not to be believed, because the material characteristics of the silicon hydrogel are not capable of making long-time discarded type lenses. There are a lot of things to pay attention to in order to properly wear contact lenses. For example, a medical optometry sheet is the premise of attention. Each pair of contact lenses is marked on the package of the basic arc, diameter, water content, diopter, and other parameters.

The hinge is not easy to break, rust and impact resistant
Ordinary glasses frames are easy to break and rust, so we always have to replace glasses frequently. Pure titanium spectacle frames are made of 'space metal' aviation materials, and strive to accompany your growth with each pair of pure titanium spectacle frames, witness every moment of your happiness, anger, sorrow, and joy. Let pure titanium spectacles become your personal little guard and the doorman for the window of the soul.
The frame size has increased.
The larger the frame is, the more obvious it is now, so the edge glare will be more obvious when the lens is polished. It interferes with the visual effect. The frame height of the new glasses must be much larger than the height of the old glasses. Because when you buy big frame glasses, they must find out the pupil height when matching outfits. When you get glasses fitted at the opticians, the opticians don't measure the pupil height. That is, the balance line of the lens should be properly moved up when the lens is processed. If it is not moved up, it cannot be seen clearly.
