Are blue light glasses good for driving at night?
Are blue light glasses helpful when driving at night? The answer is not necessarily. Anti-reflective coating on glasses is beneficial. But blue light blocking won't have any effect on your driving at night. If your glasses have an anti-reflective coating, then they might be helpful for night driving. Otherwise, they won't have any impact.
Which Glasses for Computer Are the Best?
There is no such a thing that one type of computer glasses can fit all or is the best for everybody. When selecting glasses for screen protection, the visual ability, personal preferences, the type of work, the distance between the computer user’s eye and the monitor, and other factors should also be considered.
Evolution of hard coating technology
The first generation of the use of hard coating technology began in the early 1970s, the quartz material is deposited on the surface of a resin lens under vacuum conditions, form a very hard anti-wear film. However, due to the mismatch between the thermal expansion coefficient and the film base material, it is easy to delaminate and crack the film. Instead, it forms the mottle on the surface of the lens, and the effect is not optimal.
The second generation of hard coating technology is the use of the 1980s. The surface of the resin sheet is coated with a material with high hardness and not easy to be brittle and cracked by an immersion process. At this time, anti-reflection coating lenses had appeared and gained the recognition of consumers, but the mismatch between adding hard coating and anti-reflection coating still caused serious lens wear.
The third generation of hard coating technology was developed in the 1990s, mainly in order to solve the problem of wear resistance after coating resin lenses with an anti-reflection film. The hardened material evolved into a polymer organic matrix material.
Fourth-generation coating technology is dominated by silicon atoms, in which the hardened solution contains both organic substrates. It contains inorganic ultrafine particles, including silicon elements, which make the hard coating not only tough but also hard.
The Pros of Titanium Glasses
First, titanium is used in its pure form and as an alloy to provide a highly flexible eyeglasses frame. In fact, titanium eyeglasses are flexible. So, they are able to bend without breaking and can return to their original shape.
Second, titanium glasses come with good durability. Titanium alloy metals produce the world’s most durable eyeglasses frames. Choose a titanium frame and it will be nearly impossible to break.
Third, the titanium glasses are extremely lightweight. They are about 40% lighter than the standard steel glasses frames. In addition, due to the superior strength of the titanium frame, the frames can be made thinner making for even lighter frames.
Fourth, titanium glasses have hypoallergenic properties. It is rare anyone experiences adverse skin reactions to titanium frames. There are many other options on titanium frames such as color, texture, and patterns. What’s more, titanium glasses are corrosion-resistant.
So, are titanium glasses worth it? You may have the answers.
The TR90 Spectacle Frame
TR90 frame is a kind of polymer material spectacle frame with memory, no chemical residue is released, and it meets European requirements for food-grade materials. It is currently an internationally popular ultra-light spectacle frame. TR90 frames have the characteristics of super toughness, impact resistance and abrasion resistance, and low friction coefficient, which can effectively prevent damage to the eyes and face caused by the breakage and friction of the frame during sports. Because of its specific molecular structure, it has good chemical resistance, is not easy to deform in high temperature environment, can withstand high temperature of 350 degrees in a short time, and is not easy to melt and burn. Moreover, the TR90 spectacle frame has a lubricating surface with a density of 1.14-1.15. It will float when placed in salt water. It is lighter than other plastic spectacle frames. It is about half the weight of the sheet frame and 85% of the nylon material. It can reduce the burden on the bridge of the nose and ears.
Best Ray-ban Wayfarer Alternatives - Vans Spicoli
As for the Ray-ban Wayfarer alternative, the Vans Spicoli would be recommended. If you are looking for a brand to rival Ray-ban for rock and roll col, you do not need to look much further than Vans. While better known for skate apparel, the brand also sells shades including the Spicoli frame that has a lot in common with Wayfarer. In addition, these Wayfarer glasses come at a cheap price and they are under $15.
Of course, besides these Wayfarer glasses alternatives, there are also some other choices available. You can search for them online.
What are prescription computer glasses?
Prescription computer glasses are prescription glasses designed to do computer work. They allow your eyes to focus on the computer screen, which is farther away than reading material would normally hold. These special glasses are designed to meet the visual needs of the movement.
