Is it a good idea to buy glasses online?
If the product is purchased from a reputable and trusted retailer, buying glasses online is just as safe as buying any other product online. Buying custom-made products, such as 'prescription glasses' online, is a bit more complicated than buying regular 'ready-made' glasses. All uploaded prescription glasses orders are reviewed and notified when serious errors are found in the prescription. All prescription glasses to be shipped are also carefully checked by quality control personnel to ensure that the glasses match the required prescription to the highest standard.

How do rimless titanium glasses look?
Rimless titanium glasses are the lightest frame. Rimless frames feature a half-frame at the top of the lens and a bridging bridge at the bottom of the lens. Rimless titanium glasses weigh as little as a feather because there's less framing material on your face. Rimless glasses are usually more comfortable, less visible, and usually better to wear than heavy frames. Crystal clear lenses have no bulky frames and minimize the need to hide your face and your eyes, while other frame styles are designed to be seen and therefore mask parts of your face. Rimless glasses are the lightest and easiest to wear of all the styles.
This stylish style has been popular for years and is inspired by the days of the past to provide a stylish versatile look. Rimless glasses are simple and elegant, suitable for both men and women, and can be worn anytime and anywhere. It's light and easy to wear, with a keyhole nose bridge and an adjustable silicone nose pad to keep the glasses from slipping off. You can make it as elaborate as you want.
Glasses Size - Bridge Width
The bridge width is the distance between two lenses, measured from the innermost layer of each lens. Finding the right bridge width will allow your sunglasses or glasses to be put properly on the bridge of your nose. The bridge of the nose is an essential element because even though the frame looks pretty attractive, it helps people see more clearly. The precise distance between the two lenses helps reduce the pressure on the eye, helping the nose, without putting too much pressure on the inside of the eye. The size of the eye and the size of the bridge is usually adjacent, sometimes separated by a square icon.
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.
