It is widely known that reading glasses are designed for people with
presbyopia. This group of people has difficulty in seeing close up objects
clearly. They usually have to hold reading materials farther than normal if no
vision aid is available. The term 鈥渢oo short arm鈥?is often used to describe this
problem. The symptom of presbyopia is quite similar to that of farsightedness.
Presbyopia is closely associated with the eyes鈥?natural aging Cheap
Brahim Diaz Jersey , which explains why this condition occurs
mostly in elderly people. Traditional, people use regular prescription
eyeglasses to correct myopia and hyperopia. When it comes to presbyopia which is
actually not a form of refractive error, various forms of reading glasses are
now available. The simplest form is reading glasses. And later
bifocals Cheap
Bernardo Silva Jersey , trifocals and progressive glasses were
invented. Among them, a special kind is called no prescription bifocal reading
glasses.
Reading glasses provide only near vision aid. This is a form of single vision
prescription glasses. Regular bifocal reading glasses offer two types of vision
aids, while trifocal glasses add another one. Progressive reading glasses are
even more advanced than the former two types. Yet there is still a special form
of bifocal reading glasses. No prescription bifocal reading glasses can be
considered as a variation of regular bifocal glasses. A regular bifocal lens has
two separate lens powers which are responsible for correcting nearsightedness or
farsightedness and presbyopia respectively. This design brings the huge
functional benefits of bifocal glasses. It also reflects the name of this
eyeglass category.
Some people may wonder that what are no prescription reading glasses and who
need them. It is important to be clear that a lens of this kind has only a
reading power in its lower part Cheap
Benjamin Mendy Jersey , while the upper part is left to be Plano.
In other words, only the lower section provides visual aid and the vision
through the upper section is uncorrected. The answer to the second question is
that some people without nearsightedness do not want their distance vision to be
corrected unnecessarily. They can use normal distance vision while seeing far
things.
C: No prescription bifocal reading glasses are made of lenses that are Plano
in the upper section. People without nearsightedness can use their normal
distance vision while seeing distant objects.
