How Do Blue Light Glasses Work?
Blue light has a short wavelength which makes it easy to penetrate the eyes. This means that almost all visible blue light rays can pass through the cornea and lens to the retina. Wearing blue light blocking glasses can help you to filter the harmful blue light.
Why Do My Glasses Give Me a Headache?
Why do my glasses give me a headache? There are a lot of reasons for new glasses headaches. So, in this section, we will list some of them.
Muscle strain: each eye contains six muscles. Since your eyes learn how to view the world through a new prescription, these muscles have to work harder do differently than they did before. So, this action may cause muscle strain within the eye and a headache. If you are wearing glasses for the first time or if your prescription has changed significantly, you may be prone to this effect.
Multiple lens power: if you have changed to a multiple lens power of glasses like bifocal glasses, varifocal glasses, it may be difficult to adapt in a short time. So, this change will lead to some problems such as headaches.
Poorly fitted frames: as for the issue of new glasses headaches, if you glasses fit too snugly across your nose or cause pressure behind your ears, you may get a headache. So, when purchasing a new pair of glasses, selecting a fitted one is important.
Wrong prescription: why do my glasses give me a headache? It can be caused by the wrong prescription. If your eyeglasses prescription is too weak or too strong, your eyes will become strained causing headaches. So, if you still suffer from headaches after wearing the new glasses for a few days, contact your eye doctor and check the prescription again.
Features of Beta titanium glasses frame
Beta titanium has better strength, fatigue resistance, and environmental corrosion resistance than pure titanium and other titanium alloys. The shape plasticity is very good, which can be made into wire and sheet, more lightweight. They are used to make glasses and can get more shapes and styles. It's the material for a new generation of glasses. Customers with higher requirements for style and weight can completely choose beta-titanium glasses. Because β titanium processing technology is higher than pure titanium, usually only large factories and brands will produce, and the price is higher than pure titanium glasses.
Glasses Size - Temple Length
The length of the temple is the length of the arm of your glasses. It's how far the arm is bent, all the way to where it intersects the frame. Although lengths may range from 120 to 150 mm, there are some common industry standards:135, 140, 145, and 150 mm. The temples are long enough to extend beyond your ears, so the ends can be changed to match the contours of your head behind your ears.
Why do glasses with the same prescription feel different?
The old glasses 'remodeled' your eyes. Sometimes, all data on optometry and processing are accurate, and the spectacles equipped are in full compliance with the prescription for optometry, or the power of new spectacles is exactly the same as that of the old spectacles, but you will still be dizzy when wearing the new spectacles. This is because the old glasses 'remodeled' their eyes during long-term wear. For example, the old glasses used by some people have been severely deformed. The temples are no longer in the same plane, and the optical center area of the lens will deviate from the interpupillary distance measured by the glasses at that time. However, the wearer does not mention this situation, and the eyes gradually adapt to this kind of deviation. After putting on a new pair of glasses, you will not adapt to them.
Do Blue Light Glasses Work?
When wearing blue light glasses, you may ask whether the blue light glasses really work. In fact, many users have the same troubles. To answer this question, some researchers have made research and have found that blue light glasses make it possible to remain fully engaged in our technologically advanced world, without taking on the negative effects of blue light.
With the blue light blocking glasses, you can focus on the task at hand without negative effects. Besides, with the blue light blocking glasses, you can even sleep well and reduce eye strain. You can also test your blue light glasses are real.
Do night driving glasses really work?
Yellow lenses reduce the amount of light entering your eye, reducing visibility. These darker colors block more blue light than yellow lenses. But they block more light from entering the eye, reducing visibility even more in low-light conditions. In fact, even yellow lenses reduce overall visible light to some extent because they block some blue light. This can be a good thing during the day, but not at night, when maximum visibility is key. Night driving glasses come in a variety of yellow and amber colors. The darkest lenses filter out the harshest light, but they filter out the largest amount of light, making it difficult to see in dim or dark conditions. Some people who wear night driving glasses say they can see better with them on. However, vision tests have shown that night driving glasses do not improve night vision, nor do they help drivers see pedestrians any faster than they would without glasses.
