Are Polarized Sunglasses Best For Driving?

BLUPOND night driving glasses

TAC Semi-polarized Blue light goggles are designed to change your perspective to yellow with computer blue light polarization. Anti-glare high-definition vision blue-blocking glasses protect eyes from blue light and reduce the contrast of bright blue/white glare and flash. The anti-glare night glasses limit distortion. In addition to polarized driving glasses, you can receive a night vision glasses accessory set, with the EVA glasses hard case, screwdriver, sunglasses bag, microfiber cleaning cloth, glasses clip, and night driving glasses gift box.

What Do the Numbers on Glasses Mean?

In this section, we will show you the glasses numbers meaning. These numbers on glasses frames are the measurements that indicate and describe the size of your eyeglasses frames, specifically:

1. The eye size number (it is the size of the lenses on your frame).
2. The bridge size number (the distance between the lenses).
3. The temple length number (it is the size of that part of your eyeglasses frame, which rests upon your ears).

The three numbers mentioned above are the key measurements that describe the glasses measurements of the frames in eyeglasses. For example, you will see three numbers like 51-17-145 at the temple of your glasses. These numbers help the optician to choose the best-fitted frame for your head size and facial features.

All of these three numbers are measured in millimeters. These variations in frame numbers are fitted by a skilled optician so that it should be best fitted, be comfortable and look good on the appearance.

How Do Progressive Lenses Work?

So, how do progressive glasses work? Progressive lenses allow you to see at all distances with one pair of glasses. They start with your distance prescriptions at the top of the lens and increase as you move toward the bottom of the lens. You can move your head position to allow you to focus through different areas of the lens.

Move your head upwards to see something in the distance, and hold it straight for intermediate or arm’s length vision and down for near vision for objects that are close up. Apart from the aesthetic improvement of the lens without the line segments, progressive lenses avoid the visual discontinuity or image-jump when your eyes shift from one zone to the other in non-progressive multifocals.

Which is better, MR7 lens or MR8 lens?

The refractive index of MR7 is 1.67, and its Abbe number is 32, so it has a good dyeing property. MR8 has a refractive index of 1.60 and an Abbe number of 40 or more. MR8 has stronger toughness, so it is more tensile and is not easy to break when confronted with strong impact. The lenses of MR7 and MR8 are different in the degree of heat resistance, and the heat resistance of MR7 is slightly weaker. MR7 is recommended if you want thinner and lighter lenses, but MR8 is recommended if you want higher light transmittance.

What Are Progressive Lenses?

Traditional eyeglasses are usually single vision lenses with one prescription. Progressive lenses are multiple with three prescriptions in a pair of eyeglasses. Progressive lenses let you see comfortably at different distances, allowing you to see close, near, and far without changing your glasses. There are other kinds of multifocal lenses like bifocals and trifocals, but progressive lenses differ because of their smooth transition between prescriptions.

Bifocals and trifocals work similarly to progressive lenses and feature either two or three prescriptions in a pair of glasses. These lenses have definitive lines separating the prescriptions. However, progressive lenses don’t use these lines and allow you to easily transition between prescriptions.

Hence, in the following section, we will show you 6 different types of progressive lenses.

Anti-fog lens cloth

Anti-fogging glasses cloth is composed of multiple layers of material pressed together, and the material absorbed a sufficient amount of antifogging agent. It can be directly wiped on any lens. Like spray anti-fogging agents, anti-fogging time is relatively short, and can not be wiped or washed. Long time use will affect the life of the lens. The range of lenses available is limited.
