What is the cheapest way to buy prescription glasses?
The choice of frames is not only good-looking but also has a lot to do with whether the polished glasses can be worn correctly. Therefore, special attention should be paid to the selection of spectacle frames, and the pupil distance and the optical center of the spectacle lens should be placed in a suitable position. It should also match the shape of the face so that the paired glasses are not only beautiful but also comfortable to wear. If you don’t choose a frame according to this, but choose anyone according to the general rules, the pupils will not match the optical center of the glasses, and the deflection center of the glasses will appear, causing the prism effect, which is very harmful to the eyes. How do choose a frame? Glasses are worn on the face after all, and they have a decorative effect, so you still have to see if they fit your face shape. In addition, the weight should be light and the frame size should be appropriate. It is best to measure the interpupillary distance, otherwise, it is easy to cause squint and cross-sight. It is safer for children to choose a plate frame with resin lenses. There is a wide range of options for adults. Glass lenses have higher hardness and are not easy to wear, while resin lenses have lower hardness but lightweight, good clarity, and higher protection against ultraviolet rays. Although crystals are expensive, they have high ultraviolet and infrared transmittance.
The frames should be firm.
What kind of glasses are not easy to damage? It should be said that there are only two types of such frames: full metal frames full non-metal frames. However, be careful when choosing these two frames. Younger children prefer to move, and self-control is poor, so choosing a full non-metal glasses frame is appropriate. Although the middle school children are active, the self-control will be relatively strong, so you can consider the choice of a full metal glasses frame.

Eyeglass pinches your nose.
Not only can a pair of glasses that pinch your nose be uncomfortable, but chronic stress can also lead to headaches or migraines. How you solve this problem depends on your frame material. If you're wearing a metal frame, just use your thumb to widen the plastic nose pad until the frame fits comfortably. If wearing plastic frames, after soaking the glasses arm in warm water for 30 to 60 seconds, gently press the glasses arm outward to make the glasses more comfortable. If your glasses continue to clamp your nose after adjustment, seek help from a professional optician.
Plano Lenses vs Demo Lenses
When talking about the plano lenses, demo lenses will be talked about, too. Plano lenses are different from demo lenses. Demo lenses are nothing but lenses that are fitted into the demo frames at the optical showroom and workshops. The only purpose of demo lenses is to give a realistic aesthetic of the frame to the users so that they can get an idea of how it would look with corrective lenses. However, there is also no corrective power on demo lenses.
Compared with demo lenses, plano lenses provide good quality lenses that give your protection against harmful UV rays and blue light emitted from digital screens like laptops and desktops. In addition, you can also add an anti-glare coating to the plano glasses.
Figure out the categories of driving glasses
Driving glasses are usually divided into daily and night glasses. Daily use refers to the glasses with anti-glare function and darker colors like gray, brown and gray-green, and other colors. Daily lens transmittance is over 8%. Night type usually refers to the glasses that can prevent glare from headlights of opposite vehicles and increase brightness at the same time. That is, it can prevent lights and not block the road, and can brighten and increase the visual scope. Night lenses have a transmittance of more than 75%.
