Advantages and disadvantages of using transparent polymeric materials for eyeglass lenses?
Wiki User
∙ 12y ago
Polymers are lightweight, easily manufactured and shatter resistant. They also absorb UV radiation which acts to filter UV rays from the wearer's eyes. However, polymers are easily scratched and are not as precise optically. There may also be some discoloration of the lens with time.

Why boric acid is polymeric?
Boric acid has layer like lattice. In this structure planar bo3 units arejoined by hydrogen bonds and forms a polymeric structure.
What is the mass of kevlar?
Kevalar is polymeric unit of this monomer, u can have the mass of monomer and use it for calaculating the polymeric mass.
Are nucleic acids polymers of nucleotides?
Yes, they are. Nucleic acid polymeric subunits of ribonucleotides condense to form Rna, while polymeric subunits of 2' [two prime] -deoxy-Rna condense to form Dna. So tough to explain such a small difference between Rna and Dna!
Which is the worst electrical conductor tin copper rubber air or water?
Rubber, due to polymeric nature.
Why beryllium and magnesium form polymeric hydride?
Because the electronegativities values of Be and Mg are high in comparission of other elements of the group. These two metals form poler covalent bond with hydrogen and due to polarity the units of these hydrides are linked to gather in the form of chain by hydrogen bond. so thier hydrides are called polymeric hydrides.
Examples of the difference between plastic and polymers?
The so called "plastic materials" are polymeric materials.
What is ploymeric material?
Polymeric materials are those materials that have large molecules. These materials are usually carbon-based and the result of monomers bonding chemically.

Is plastic an example of synthetic polymer?
Yes, it is correct; organic plastic materials are polymeric compounds.

What is fado meter?
It is an instrument used to determine the resistance to fading of a pigment or dye on natural or synthetic polymeric materials

What is as strong as metal?
Not all metals are so strong. Many polymeric materials, carbon fibers, etc. have very good mechanical properties.

Is jute an element or a homogeneous mixture?
Neither; it is a plant fiber composed mostly of cellulose (a sugar polymer) but with many other plant polymeric materials, too.
Is ozonation sanitizing safe?
It is unsafe for bacteria and virii. It is unsafe to be in the room when it is being done. It can be hard on most polymeric materials left in the area to be sanitized. But it is very efficacious.
