Choose the right color for your glasses.

Black, of course, is the classic color. For boys, wearing black frame glasses can promote the stereo sense of their facial features. Black is the most recognizable color. Black-rimmed glasses will make the outline of a boy's face clearer and make his appearance more handsome. Silver-framed glasses have all the features of metal-framed glasses. But compared to rose gold, silver is a bit more understatement, and it's very versatile and can be worn by guys with different skin tones. Those with darker skin tones can try deep burgundy shades, like popular brown and amber glass frames. Such a frame won't show too dull and won't show too abrupt. At the same time, it will be more harmonious to use a dark skin tone to foil.


Driving Glasses - Conant

What Are High Index Lenses?

High index lenses are eyeglasses lenses that are designed to be thinner and lighter than regular lenses. High-index lenses have a high refractive index than their conventional counterparts. High index lenses are recommended for people who have significantly high refractive errors and strong prescriptions for nearsightedness, farsightedness or astigmatism.

High index lenses are thinner, lighter and more appealing than standard lenses, but they come in several different indexes such as 1.67 high index lenses and 1.74 high index lenses. In this post, we will focus on the 1.67 high index lenses and 1.74 high index lenses.


Are rimless glasses in style 2022?

Now the glasses design concept changes with each passing day. The glasses are more and more in line with the aesthetic requirements of modern people, adding style and elegant demeanor to your clothing collocation. Rimless frames are not obvious either in appearance or weight, relieving some of the distress caused by myopia. Rimless glasses not only give you a wider view, but reduce overall weight, and have become a favorite of many fashion trendsetters. Are these rimless glasses your style?



The lenses of prescription glasses

Common materials for lenses include glass, resin, and PC. The glass is fragile and heavy, and few people wear it anymore. PC film is tough and not fragile, but it is not resistant to high temperature and the surface is easily scratched. The most common type of lens on the market today is the resin lens, which is light in weight, hard to break, and reasonable in price. At present, it is generally recommended that you choose resin sheets, and it is recommended that people with ultra-high myopia choose glass sheets.

Generally, lenses can be divided into spherical and aspherical surfaces according to different curvature designs. When choosing, refer to the degree of the eye. For people with lower degrees, There are fewer differences between the two shapes. For people with moderate to high myopia, aspherical lenses will have better imaging effects and clearer vision.

When choosing a lens, a parameter that is often mentioned is the refractive index. Common refractive indexes are 1.56, 1.60, 1.67, and 1.74. With the same degree, the higher the refractive index, the thinner the lens.


The Benefits of Anti-Glare Glasses

As is well known, glare is the excessive brightness caused by direct light or reflected light. It often occurs when sunlight bounces off a reflective surface like water or snow. Of course, anti-glare glasses can also be caused by other factors.

Standard plastic lenses are able to reflect approximately 8% of the light that reaches your glasses and high-index lenses often reflect up to 12% of available light. Hence, anti-glare glasses come in a lot of advantages.

The anti-reflective glasses can reduce eye strain and make your eyeglasses look more attractive because the anti-reflective coating can eliminate reflections from the front and back surfaces of your eyeglass lenses. With this feature, more light can pass through your lenses to improve your vision with fewer distractions and the lenses look nearly invisible.

In addition, anti-glare glasses are helpful to high-index lenses, which reflect more light than regular plastic lenses. In general, the higher the index of refraction of the lens material, the more light will be reflected from the surface of the lenses.

Anti-glare glasses can protect your eyes from UV rays (sunlight that doesn’t appear on our visual spectrum). This feature can be enhanced by some photochromatic or polarized lenses.



When do you need prism glasses?

If you experience symptoms of headache, dizziness, and nausea, then these symptoms may be caused by a subtle disorder between the eyes. This situation is called Binocular Vision Dysfunction(BVD). Double vision occurs in the situation that light enters the eye at the wrong angle and sends two different images to the brain. Some people have diplopia, where they can see only one image, and flat images are often blurry. Prism glasses can help to change visual deformities. Prism lenses can be helpful to prevent myopia and farsightedness in both eyes. If vision deteriorates in one eye, the eye muscle can use an external corrective prism to prevent blindness. Standard glasses are made of a combination of prisms that can correct the focal length errors and corneal curvature. The prism moves the image up and down or left and right to form an overall view.
