Why are eyeglass frames are so expensive?

The industrial chain has factories, brand owners, regional general agents, retailers. Each link needs to share the risk and profit. They have high operating costs. In addition to the well-known rent, they have the costs of labor, decoration, and so on. There is another important reason. It is the inventory loss because of the style problems. This aspect of the cost must be amortized. From the structure and appearance design of the glasses frame, the development and application of raw materials, processing technology, to manufacturing equipment and procedures, the actual cost may be much higher.


Replace the nose pad on your glasses

Remove the screws clockwise and use a toothpick to remove the things left of the broken pads so that the new one can be installed. The next step is to fix the nose pad that we just removed from it. Hold the glasses and then the hole for the nose pad is up, then place the nose pad in and press it with your finger. Then you can see that the round hole in the nose pad overlays with the round hole in that part, and at this time, you can turn the screws. When you finally turn it, you usually turn it three times to hold the nose rest in place. Often, the nose pad can be swung back and forth after installation. This is to match the different shapes of our noses.



ShadyVEU HD blue light blocking Glasses

The anti-reflective yellow and amber lenses are the best choices for outdoor vision protection, as they reduce high-intensity glare from bright lights (headlights, LED signs, etc.) at night. They are suitable for daytime driving with a clear vision, especially in low light conditions such as rain, haze, and winter. Yellow and amber-colored lenses help block out our computer screens, smartphones, games consoles, tablets, and TVs, helping to prevent melatonin suppression and thus helping wearers fall asleep faster.

They are suitable for sports, hunting, fishing, cycling, work, practical and construction work, day driving, night driving, bright days, snow days, and low light conditions.


Which kind of lens can correct myopia?

Myopia is corrected by glasses with concave lenses, which are the thinnest in the center and thicker at the edges. The strength of the lens used to improve myopia is measured in diopter (D). The prescription for myopic glasses always begins with a minus sign. The higher the magnification of the lens, the better the effect of correcting myopia. High refractive index lenses are usually recommended to correct myopia with a diopter greater than -3.00. The lenses are thinner and lighter than regular plastic lenses, making them more attractive and comfortable. At the same time, an anti-reflective coating is strongly recommended for the correction of myopia lenses. The augmented reality coating eliminates scattered reflections in the lenses, making them look thinner and more attractive.



An oval face fits all frames.

It is still expensive to get glasses, so it is best to know what shape you are suitable for before getting glasses. A suitable pair of glasses frame, not only can make the vision more clear but can increase the appearance. There are different tips and methods for choosing glasses for different face types. Glasses can not only assist myopia, but play the role of modifying the face, so how should different face types choose suitable glasses?

If you have an oval face, you should be lucky to have a uniform shape that allows you to pull off all frames. The widest part of this face is located in the front part and moves smoothly to the forehead and the sides of the chin. Due to uniform proportion, the face has no special defect to cover.


How to drive at night with glasses?

If you need to wear glasses while driving, you'll need special glasses when driving at night, because common lenses reflect oncoming lights, which produces a faint glare. This will reduce your visibility. It's OK to wear contact lenses while driving. As you get older, your eyes become more sensitive to glare. Ordinary sunglasses or goggles are only suitable for wearing during the day, driving at night will seriously affect the vision (national standards stipulate that light transmittance of night driving glasses must be greater than75%). Although the all-weather driving glasses can weaken the strong lights, the vision darkens and affects road safety which does not meet the national standards for driving glasses at night. You should choose functional driving glasses that can block strong light, glare and increase the field of vision. This can effectively reduce the glare of the car lights but can filter out the extra harmful light. When worn at night, it can soften the strong lights and make the vision clearer. In this way, the safety of drivers is ensured, the fatigue of eyes is alleviated, and the radiation damage of harmful lights to glasses is prevented.



Understand the impact of frame selection on the lens

Frame size is an important consideration when using progressive lenses because some progressive lenses work better in frames of different sizes. Since progressive lenses allow you to see at all distances, it's important that the whole range of vision fits within the frame. Therefore, very short lenses and larger lenses are not suitable for progressive lenses.
