Be careful of buying bifocal glasses online
People
who have experience of ordering some goods on the Internet know probably
some of the benefits offered by this source. For example, it is
needless for the buyers to leave their homes or offices. Simple enough, a
few clicks of the mouse can make all things done. Eyeglass products are
also widely available online now. Most people tender to get similar
benefits and try to purchase spectacles from online retailers. Well, it
is ok to get ordinary eyeglasses like regular prescription eyeglasses,
sunglasses, goggles and so on. However, when it comes to bifocal
glasses online, additional care is absolutely necessary.
Online
retailers will certainly feel additional challenge when they try to
provide bifocal reading glasses for customers through the Internet. The
reason is that fitting these bifocal lenses is really an intricate
process which involves basically an additional prescription power. In
fact, this is the similar case in trifocal eyeglasses and progressive
eyeglasses. These three forms all belong to multifocal eyeglasses. This
term suggests an obvious point that more than one power should be fitted
into a single lens. This involves surely more skill requirements on an
optician or an optometrist. Since the purchaser is not present, it is
relatively harder for an optician or optometrist at the side of an
online retailer to get the target eyes perfectly fitted. This is why
most sites shy away from offering bifocal glasses online.
Another
challenge associated with purchasing online bifocal reading glasses is
that now there are lots of special-purpose designs. For instance, there
are reading segments in different shapes that can be added into a
primary lens. D segment, round segment and rectangle segment are
possible customized styles. These customized bifocal reading glasses
require certainly extra measurements of the customer’s eyes. Even for
those retailers courageous enough to provide bifocal
glasses online, an in-depth discussion with the customer is
indispensible.
