Bifocal Contact Lenses ExplainedIt's time to know more about bifocal contact lenses especially if you've noticed that your currecnt eyewear does not answer your needs any more. Do you find that you are holding close objects further and further away from your eyes in order to bring them into focus? If unwelcome changes in how you view the world are resulting from presbyopia or myopia perhaps you should consider the advantages of wearing bifocal contact lenses. When Bifocals Become A NecessityBifocals are a common suggestion by optometrists who are trying to solve vision problems for patients who are aged 40+. One of the common complaints of people in this age group is difficulty switching their visual focus comfortable from far objects to those near at hand. The vision problems are different depending on the distance that is involved so it's quite apparent that an ordinary pair of contacts or eyeglasses will not produce an adequate solution. Bifocal BasicsWhen people need different prescription lenses for near vision and far vision then bifocal lenses are the obvious remedy. With them you do not have to deal with unwieldy and cumbersome pairs of eyeglasses. These lenses provide you with two different types of visual assistance, that is two prescription strengths in one contact lens. This means you can once again focus clearly on objects at any distance, and no one but you will even have to know you are wearing them. Soft Or Rigid (RGP)You can find soft bifocal contacts now available or you can choose the hard lenses that are constructed from rigid, gas permeable materials (RGP). Bifocal lenses that are categorized as soft contacts are made from pliable materials. Nowadays you can even buy your bifocals made from silicone hydrogel - a new-generation material that allows extra oxygen to the cornea.
Other bifocals are known as RGP (rigid gas permeable) which are smaller in size and provide a more exacting fit to the curvature of the eye. RGP, or GP, lenses are not as readily available in disposable styles. Types Of Bifocal Contact LensesThere is a type of bifocal contact lens that produces simultaneous vision but it requires you to use both power magnifications at the same time. Your eyes will learn to select the appropriate magnification strength that is needed. There are two types of bifocal lenses that incorporates this design:
Concentric ring bifocals have the near distance prescription in the center and the far distance prescription on the outside. Examples of concentric ring bifocal contacts are: Aspheric designed bifocal lenses are created with blended magnification strengths in each lens which is quite similar in construction to contacts with progressive lenses. Examples of aspheric bifocal contacts are:
Each person will be able to adjust and adapt more quickly to one specific type of lens. You may even have to commit to some trial and error under your doctor's supervision in order to adequately determine which type of bifocal contact lenses are best suited for your eyes. You might even consider being fitted with a pair of alternating vision bifocal lenses, or translating lenses, as they are also called. This design has a distinct line of demarcation much like the regular pair of bifocal eyeglasses. Alternating vision lenses allows your pupil to alternate between the two magnification strengths according to the distances and objects that are involved. Your eyes become accustomed to the up and down shift that these contacts require and soon you don't even notice that you are alternating your eyes, it is just a part of normal life. These lenses do have a diameter that is a great deal smaller which means that for proper vision the bifocals must stay perfectly positioned at all times. This is why most are GP (gas permeable) lenses which means they are smaller and better fitting than normal soft contacts. Your eye doctor can perform an eye exam and he will be able to suggest the best type of bifocal contact lenses for your needs. The decision is based on the "add" (near) prescription strength of the lenses, your visual problems, and the size of the pupils in your eyes. What kind of contact lenses are you wearing now?
