How to Choose Glasses for Big Heads?
In this section, we will show you how to choose an eyeglasses frame for large heads. If you do not know how to choose, keep on your reading to find some solutions.
Rectangular frames: Rectangular frames add angle and can slim down the appearance of a larger head. So, if you have a big head, try the rectangular frames glasses.
Oversized frames: if you have a big head, the oversized frames would be a good choice. Oversized glasses will balance out your larger features.
Wayfarer frames: whether your style is retro or geek chic, you will find a perfect fit in trapezoidal wayfarer. The thick angular frames offset rounder cheeks and draw attention down from the forehead. So, if you have a large head, try this style.
When choosing glasses for large heads, you should also find the right shape and color for your signature look and style. While there are a lot of glasses styles for big heads, you should consider glasses with long enough temple length, the length between the hinge of your frames and where they bend around the ear. This measurement is critical for overall comfort, especially on your temples and near your ears.
So, from the above information, you have learned how to choose glasses for big heads.
The purpose of glasses donation activities.
Regular social donation activities should be carried out in a planned way. For the poor in the rural areas of the disaster area and the poor in the urban districts, donations of materials or funds can not only feel the warmth and humanistic care of society in life and material, quickly resuming production and rebuilding homes. It gives them a sense of psychological security and stability, which is more practical than physical help.
What Are the Advantages of Progressive Lenses?
We have shown what the progressive lenses are in the above part. Do you know what the advantages of progressive lenses are？.
1. Only need a pair of eyeglasses. As mentioned in the above section, with progressive lenses, you just need a pair of eyeglasses and there is no need for you to change different glasses constantly.
2. No unsightly bifocal line. Progressive lenses come with the multifocal lens without a multifocal line. And there is a smooth shift in lens strength, you don’t have to deal with any sudden changes in clarity.
3. More comfortable. Due to no visible line, you might feel more comfortable with a progressive lens.
Can you wear blue light glasses while driving?
The damage of blue light has a cumulative effect. The longer the exposure time is, the more serious the damage of retinal cells will be, which will eventually lead to irreversible damage of the structure and function of the retina. Once the retina has permanent damage, degeneration will directly affect the metabolism and function of photoreceptor cells, resulting in vision loss. It depends on the glasses you're wearing. The function of anti-blue light glasses depends on the material of the glasses. Some blue light glasses have a special anti-reflective coating, which can reduce glare. These glasses are definitely helpful when driving at night.
What are NXT Lenses?
NXT lenses are made of Trivex materials. Trivex (Chinese name: Ethyl Carbamate Polymer) was invented by PPG in 2001.
Impact resistance:
Impact resistance is the main feature of the NXT lens. As a visual armor material originally used in the military field, Trivex has effective impact protection to the eye when it is most demanded. It is 10 times stronger than PC lenses in impact resistance and will last for life under normal use. It is the only explosion-proof safety lens on the market that can withstand external forces and turns.
Patented color injection technology :
Color representation is another important feature of NXT lenses. The biggest defect of the regular lens in dyeing is color aberration. The same color of the lens with different luminosity will produce different effects. The higher the refractive index, the serious the error. NXT lenses are a breakthrough in this respect. The patented color injection technology that infuses the color into the raw material gives the lens a natural color, ensuring that color aberrations are minimized and that they do not fade or change color over time or over long periods of use like other materials.
Abbe number and internal stress:
The Abbe number of NXT lenses made of Trivex is 43~45, which is close to CR39(58) and higher than PC lenses (29~32) and high folding lenses (32~41). At the same time, because the NXT lens is produced by the casting process, there is no stress in the finished lens, which further reduces the rainbow phenomenon, providing a guarantee for the clear visual effect and reducing eye fatigue.
Weight:
The specific gravity of NXT lens is 1.11g/cm3, 16% lighter than CR39 (1.32g/cm3) and 10% lighter than PC tablet (1.22g/cm3). The Trivex 1.53NXT medium-fold lens is so light that it can float.
What Are Progressive Lenses?
Progressive lenses have grown in popularity and are one of the most common solutions to treat vision loss that occurs with age or presbyopia. This eye condition occurs when the eye loses some of its flexibility and ability to adjust to clear seeing objects at different distances. Presbyopia often occurs among adults who are over age 40 and is very easy to correct with a proper and prompt diagnosis.
Progressive lenses are often used to correct this eye condition. Progressive lenses are a modern alternative to bifocal glasses, which provides two prescriptions in a single set of glasses. Bifocal glasses are a better solution than carrying around multiple pairs of glasses. Progressive lenses were developed to resolve some of those common issues and to provide better aesthetics. Progressive lenses provide a smooth transition and can accommodate up to three prescriptions and are a replacement for both bifocals and trifocals.
What glasses are suitable for a person with a round face?
Pay attention to choosing the right shape. The too-small glasses for a round face will make it look bigger. You should choose some large-frame glasses or the irregular glasses that have become so popular in recent years. You can choose long or square frames, and angular long and square frames will increase the line of your face, making your face look more three-dimensional. You had better match the thin glasses that takes curve slightly to reconcile the whole feeling. Just make sure that the size of the glasses is proportional to the size of the face.
