What are polarized lenses for?
Polarized lenses contain a layer of polarizing plates in which molecular chains form a light-grating structure in which dichromatic pigments, which absorb polarized light, are evenly distributed. A beam of light is absorbed when it vibrates in the same direction as the bars of the molecular chain of the polarized lens. The grating direction formed by the molecular chain of the polarizer is the axial direction of the polarizer, which is generally horizontal. When polarized lenses are worn, they absorb all the light that vibrates horizontally, thus absorbing the glare and preventing it from reaching the eyes.

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.
Cyxus Blue-Light-Blocking Glasses for Kids
So the price you pay for a pair of blue light blocking lenses depends more on the quality and style of the frame than on the effectiveness of the lens. The glasses, which come in a black and pink frame, come with a waterproof case in the shape of a rabbit, a cleaning cloth, and a blue-light flashlight to test the lenses. The brand's boxes come in very cute kids' colors and shape to make it fun. (In addition to the all-black version, there are blue, green, and red versions.)
Beta titanium
β titanium refers to a particle titanium material that is completed by delayed cooling at the zero bound point state of titanium and does not belong to the alloy. Practical applications will often be processed into alloys to increase their applicability. Although the purity of β titanium is not comparable to pure titanium, its strength, fatigue resistance, and environmental corrosion resistance are better than pure titanium. It has higher strength than pure titanium and other titanium alloys, and the corrosion resistance is stronger and has better elasticity, It is not easy to deform, and is lighter.

Trifocal glasses can provide correction for some eye conditions including presbyopia and cataracts. Presbyopia often occurs in people who are between the age of 40 and 60. People’s eyesight starts to deteriorate and they are unable to focus at near. Wearing trifocal glasses can help correct blurred vision, eye strain, and headaches. The trifocal intraocular lens placed during cataract surgery can also resolve cataracts.
From above, you have learned some information about trifocal lenses. But what are the pros and cons of trifocal lenses? So, in the following section, we will focus on the advantages and disadvantages of trifocal glasses.
