What Do Blue-Blocking Glasses Do?

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.


Aluminum Night Driving Glasses

These night vision glasses feature advanced HD technology. The aluminum frame is lightweight, allowing you to comfortably wear your driving glasses and reduce glare for safe driving. Because the lenses are yellow, these glasses act as night vision goggles to reduce glare, reflections, and their negative effects, while improving and brightening the visual area. Polarized lenses have a special anti-reflective coating that eliminates intense reflected light and reduces glare and scattered reflections. They can double as day and night glasses, improving clarity around the clock.



Eyeglass pinches your nose.

Not only can a pair of glasses that pinch your nose be uncomfortable, but chronic stress can also lead to headaches or migraines. How you solve this problem depends on your frame material. If you're wearing a metal frame, just use your thumb to widen the plastic nose pad until the frame fits comfortably. If wearing plastic frames, after soaking the glasses arm in warm water for 30 to 60 seconds, gently press the glasses arm outward to make the glasses more comfortable. If your glasses continue to clamp your nose after adjustment, seek help from a professional optician.


The advantages of contact lenses

Contact lenses are worn directly over the eye. Contact lenses are tightly attached to the surface of the eye and can always follow the eye, so you can maintain the same open field of vision like a normal person. You can participate in sports and outdoor activities without worrying about your glasses falling off or breaking. You can even use colored contact lenses to change the color of your eyes. Some girls, in particular, can make their eyes look bigger and more beautiful with the help of various color contacts.



What Should You Do If Your Glasses Are Broken?

A professional eyewear repair shop ensures accurate repair. Fixing metal frames requires special welding equipment and expertise, and you could injure yourself or your frame if you try to weld them by yourself. A professional can make sure your glasses are accurately repaired. If you're not precise enough in repairing a damaged frame, you may be able to see through a crooked pair of glasses, which can damage your vision. Plastic frames are easier to fix than metal frames. Fixing the frames by yourself poses a greater risk than having them repaired by a professional.


You can choose driving goggles.

The goggles partly filter the far-light from the car. Products sold online include glasses with yellow lenses and yellow translucent shades that clip onto car shades. Shades block out oncoming far-light, while glasses prevent rearview mirror glare from vehicles behind. Most of the light emitted by car headlights is short-wavelength ultraviolet and blue light. The yellow polyester blocks them while allowing the longer wavelengths of red and green light to pass through, making the headlights softer when seen through the goggles without reducing the brightness of the road and the surrounding environment.

Metal frames have many benefits.

It has a certain hardness, good softness, good elasticity, wear resistance, corrosion resistance, gloss, and good color and luster.?For example, for the high nickel alloy frame, nickel content reaches more than 80%. It mainly has nickel-chromium alloy, manganese nickel alloy. High nickel alloy’s corrosion resistance is better. In addition, the material elasticity is good.?Titanium frame has a high melting point, light material, strong corrosion resistance, and solid electroplating. The eyeglass frame that uses pure titanium is deft and comfortable, more in accord with human body engineering. And flexibility is good, long-term use is not out of shape. And they do not fade, do not cause skin allergy, relatively durable.? Memory titanium alloy frame refers to a new alloy made up of nickel and titanium according to the atomic ratio of 1:1.?Memory titanium is more resistant to corrosion than high nickel alloys but less resistant than pure titanium and β-titanium.
