How Can You Tell If Sunglasses Are Polarized?

Optix 55 day/night driving glasses

These glasses are designed to provide anti-glare and UV protection. They have a flexible plastic lens and frame that can be used over prescription glasses. They use polarized lenses to make the image look sharper. They help reduce glare, reflection, and its negative effects while improving and brightening the visual area.


Types of aspheric lenses

There are two types of aspheric lenses: single aspheric surface (single aspheric surface for short, different from the outer aspheric surface and inner aspheric surface) and double aspheric surface (double aspheric surface for short). For the outer aspheric surface, convex is an aspheric surface and concave is a spherical surface. For the inner aspheric surface, a convex surface is a sphere, and a concave surface is an aspheric surface. In addition to correcting aberrations, the double aspheric lens also improves the effective field of vision compared to the single aspheric surface. When people's eyes look through the edge of the lens to see things, like driving when looking at the reflective mirror, it often affects vision because of the large aberration at the edge of the lens. Previous designs of aspheric plates have analyzed a single ray of light passing through the center of the pupil. Wavefront technology controls the entire beam of light passing through the pupil, eliminating high-order aberrations.

Do you need to wear glasses to drive?

In the evening, lights from street lamps, buildings, and other vehicles create a lot of reflection on the windshield, making it hard to see. It's even worse when it rains. But if your glasses have an anti-reflective coating, they can reduce the glare and reflections, allowing you to see more clearly while driving at night.



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.

What Is an Aspherical Lens?

An aspheric lens is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.

The aspheric lens’s more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter and sometimes cheaper than the multi-lens design.

Aspheric lenses are flatter than traditional lenses, but they still offer the same vision-enhancing benefits. They have a more attractive profile because there is less curvature. In addition, aspherical lenses have a more complex front surface with a gradual curve so that they can perform better by improving the way light refracts onto the retina.

Besides, most aspherical lenses are high-index, which, when combined with the aspheric design, offers a slimmer and lighter option for people who wear glasses so as to improve the look and feel.
