Long years ago, you have to wear two sets of eyeglasses, then doctors discovered the lens at the bifocal eye-glasses,then recently they do the same thing in a bifocal contact lens. The lens is divided in to two halves,one upper and the other is lower and often it could be in concentric circles,one lens on the interior part and the other is on the part.

Who need bifocal lenses?

People who suffer from Presbyopia that causes difficulty focusing on things which are near and this does not develop after the age 40.They are nearsightedness and farsightedness and suffer from the eye-glasses that are usually with thick lenses and a across them (they become two lenses in-one ).These eye-glasses have a few problems: First :They are large, Second: They're nearly unattractive, Third: It is difficult to adjust to them when you have to look up or look down.All these issues cause dizziness during adapting to these bifocal lenses.The only option for these people for long years back was the eye-glasses even after contact lenses got on the market.

Today,contact lenses offer bifocal contact lenses which are soft,rigid and with gasoline permeable materials.It is double lens,as if you are wearing two sets of glasses in the same time.

With a set of bifocal contact lenses,your eye begins slowly to change to the difference of parts as the muscles of the eye coordinate and be trained automatically from and to the correct lens that is required at this time.Example: If somebody is reading,so the vision has to be fixed to see the close things at this time,so the student of the eye will be directed to the lens that correct the vision and light will be refracted in to the position of the retina that will help in close reading.But if you begin to look off at things which are far away-as wanting to the sky-the target of the eye will be directed at this time to the lens that help you to see the distant point.All of this is due to the different prescription lens of the contacts that have the power to refract the light at different angles and correct the vision due to different viewing.

That will be better? A bifocal lens inside the conventional eye-glasses OR a bifocal contact lens?

You've to choose which type you prefer.As some people have great problems and difficulties in wearing the contact lenses as they considered this difficult routine to place in and take out them,even by using specific kind that stay for all the morning,whole the week or maybe more than a week- they have to change them eventually,so they consider wearing contact lens a big problem.These people might get some hope by the advancement of the manufacture and the styles of contact lenses as these contacts became easier to maintain and very easy to control.

Contact lenses can be quite useful and fit higher than a pair of old-fashioned eye-glasses for all those who work in a hazardous environment or who wear any type of equipment like goggles.Conversely,for people that work using dangerous gaseous substances environment,contact lenses won't matches them.So you've to take the advise from your eye-care professional to help you to take the proper decision and to choose the best alternative either to wear eye-glasses or contact lenses.

There are certainly a lot of varieties of contacts,like:

1-Alternative-Design:

They are the same to bifocal eye-glasses,half the half for distant objects and lens for near objects. We discovered needs by searching the Boston Guardian.

2-Translating-Design:

There's a line separating them and they are also the same as bifocal eye-glasses,the near correction is underneath the distance correction.It is flat on underneath for that cause of keeping without activity within your eye while flashing.

3-Concentric-Design:

Whilst the outer part can see the distant objects or vice-versa Internal part can see near objects.

4-Mono-vision-Design:

You wear one lens in one eye and the other in the other eye.You wear to look at the remote objects within the dominant eye.

5-Asferic-Design:

The near and the distant vision are located at the center of the lens.Usually the correction for near vision is at the center while the correction of the distant vision surrounds it and this is often changed in certain situations according to the advise of the eye-care specialist.

6-Simultaneous-Design:

This kind has the ability to combine both the near sight and the distant sight,they fill the section of the pupil (element of the eye) and the eyes can adjust to that and can translate the circle decision according to how far or close you are watching.This is really because the light all the time from near and far objects can be centered on at the same time.These kinds of lenses might be problematic as by looking through the lens,the eye requires both : in focus and out of focus at the same time.This is due to some light from the far objects go through the near vision and vice versa,so the head has to correct the desired image.

Finally,when you choose to wear bifocal contacts,you have to:

1-Ask your physician to know if contact lenses can fits you or not and also what sort of them you can get.

2-Ask your pals or relatives if any one of them have the knowledge of wearing contact lenses.

3-Put in your concern that it might take time to locate contact lenses that may be comfortable and fit you.

4-Some organizations can allow you to test their lenses firstly,so by this giving you can have a free trial wear period to find out if these lenses can change along with your eyes or not.

5-You can check the reduced stores for contacts,they are online stores.

6-You have to find out that the bifocal lenses depends on your budget..
