Glasses Size - Frame Width
To really know how big a frame is, and how it will look on your face, you have to determine the width of the entire frame. The outer width of the frame is the distance between the visible areas on the left and right sides of the frame, namely, the distance between the frame and the junction of the two temples. The inner width of the frame is the distance between the inner sides of the two temples at 60mm behind the plane of the lens. This is just the contact point between the temple and the human temple. If it is too tight or too loose, it will affect the wearing comfort. The weight of the frame is evenly distributed across the bridge of the nose (or evenly distributed between the two nose pads on the bridge of the nose).
Look at the quality of the frame.
Put the glasses flat in front of your eyes, and see if the color of the temples is different in-depth or light under the same light intensity. Sometimes, due to the mistakes in processing, the color asymmetry of the left and right temples will appear.Technology is the quality assurance of the frame, and a frame of fine technology is often reflected in the details.Pay more attention to the welding point near the metal frame to see if there are cracks.
The thermal effect during welding changes the stress structure of the material, or the weld defect, material fatigue, and so on will make it easy to fracture.Attention should be paid to see if the two sides of the stipules of the lens frame are symmetrical and if the fixation is safe.
Buy Glasses For Kids - Appropriate Frame
To choose a frame for the child, we must first consider the measurement of the bridge of the nose of the child, and the pupil distance. Furthermore, if the eye is farsighted and the pupil distance is too large, it will produce the prism effect from the bottom out. If it is myopia and the pupil distance is too large, it will produce the prism effect bottom-inward. If the pupil distance is too small, it will have the opposite effect. The frame should be light, light glasses will not affect the development and shape of the child's nose bone.
Why is a prescription for glasses different from a prescription for contact lenses?
The frame glasses degrees are the optometric degrees of the eye, and the difference between the frame glasses degrees and the contact lens degrees is mainly due to the different contact distances between the two lenses and the eye. Usually, degrees of contact lenses and glasses need to be converted by a professional through vertex diopter. The conversion formula is Fc=Fs/(1-d×Fs). In the formula, Fc is the diopter of contact lens, Fs is the diopter of glasses frame lens, and D is the distance between frame glasses lens and cornea. Assuming that the prescription of frame glasses is -4.00d and the distance between lens apex is 12mm, the prescription of contact lenses is -4.00/ [1-0.012×(-4.00)] = -3.82d.
How To Choose Better Night Driving Glasses?
Choose and buy glasses to use a special night with anti - strong night driving lens. The demand is to block 80-90% of the strong lights and harmful lights, and at the same time to make the road more clearly. Choose glasses with thicker lenses, they are more durable and protect the eyes of drivers against irritation and accidental breakage. As common sunglasses and color-changing glasses are only suitable for daytime wear, wearing them at night will seriously affect the driver's vision.
Common light yellow night driving glasses can only block a small amount of light, and is not very suitable for night driving glasses standards. Therefore, in the choice of lenses of night driving glasses, we must do the selection and demonstration of the national authority of the formal institutions to test products, to achieve the desired effect in actual use. Don't buy products that are not up to standards from vendors. Such products not only do not block the lights but may affect the driver to see the road ahead, affecting the safety of the train operation.
