Big Grin Ready to wear bifocal contact lenses
Long years ago, you've 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 may 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 doesn't develop after the age 40.They are nearsightedness and farsightedness and suffer from the eye-glasses that are generally 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 ugly, Third: It is difficult to conform to them when you have to look up or look down.All these issues cause vertigo 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 provide bifocal contact lenses which are smooth,rigid and with gas permeable materials.It is combined lens,as in case you are carrying two sets of glasses in the same time.

Using a set of bifocal lenses,your eye begins slowly to adjust to the difference of parts as the muscles of the eye coordinate and be trained automatically from and to the correct lens that's needed at this time.Example: If someone 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 aid in close reading.But if you begin to look off at things which are far away-as looking 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 connections that have the power to refract the light at different angles and correct the vision due to different viewing.

Which is better? A bifocal lens inside the conventional eye-glasses OR a bifocal contact lens?

You have to choose which form you prefer.As some people have great problems and difficulties in wearing the contact lenses as they considered this difficult regime to place in and take-out them,even by using special kind that stay for the morning,whole the week or maybe more than the usual week- they have to change them eventually,so they consider wearing contact lens a big issue.These people could possibly get some hope by the creativity of the manufacture and the models of contact lenses as these contacts became easier to maintain and quite simple to manage. This thought-provoking needs portfolio has a few wonderful lessons for the purpose of this activity.

Contact lenses can be quite useful and fit greater than a couple of conventional eye-glasses for anyone who work in a hazardous environment or who wear any type of equipment like glasses.Conversely,for people that work in a few dangerous gaseous chemicals environment,contact lenses will not matches them.So you've to take the guide from your eye-care professional to help you to take the correct choice and to pick the best alternative both to wear eye-glasses or contact lenses.

There are always a lot of varieties of lenses,like:

1-Alternative-Design:

They are exactly the same to bifocal eye-glasses,half the lens for near objects and half for distant objects.

2-Translating-Design:

They're also the same as bifocal eye-glasses,the near correction is under the distance correction and there is a line splitting up them.It is flat on the bottom for that cause of keeping without motion in your eye while flashing.

3-Concentric-Design:

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

4-Mono-vision-Design:

You wear one lens in one eye and the other in the other eye.You wear to see the remote objects inside the dominant eye.

5-Asferic-Design:

The near and the distant vision are observed 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 can be changed in some situations based on the advise of the eye-care specialist.

6-Simultaneous-Design:

This type has the ability to blend both the near sight and the distant sight,they fill the area of the pupil (a part of the eye) and the eyes can change to that and can interpret the range choice according to how far or close you're viewing.This is because the light all the time from near and far objects can be centered on at the same time.These sorts of contacts might be problematic as by looking through the lens,the eye requires both : in focus and out of focus at the same time.This arrives 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 determine to wear bifocal lenses,you have to:

1-Ask your doctor to learn if contact lenses can suits you or not and also which kind of them you can buy.

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

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

4-Some organizations can allow you to use their lenses firstly,so by this offering you can have a free trial use period to-see if these lenses can change together with your eyes or not.

5-You can check always the reduced stores for lenses,they are on the web stores.

6-You need to know the bifocal lenses is determined by your budget..
