Bifocal contacts are designed for people with a condition known as presbyopia. The condition causes a person to hold reading materials away from her eyes to see clearly. The lenses have two prescriptions; one for distance and one for reading and seeing close up. However, first-time wearers must undergo a period of adjustment. Depending on your level of eye sensitivity, you can get used to your lenses in a matter of weeks.
Contact lenses allow you to enjoy clear vision without having to wear unsightly or restrictive eyeglasses. But for many people, vision worsens with age, making reading glasses a necessity. After recent advancements in eye care technology, bifocal contacts are an option for those who need help seeing both far away and nearby. There are some disadvantages to these lenses, though.
In the past, if you had astigmatism and needed bifocals you could only wear glasses. Advances in contact lenses mean that even with both conditions, there are choices beyond glasses.
Acuvue bifocal contact lenses are manufactured by Vistakon of Johnson & Johnson. The Acuvue bifocal contact lens, also known as a multifocal lens, allows you to shift your focus between far and near distances.
Bifocal contact lenses require the same kind of cleaning care that regular contact lenses do. Contact lenses are made in different types of materials, and the type of material that your lenses are made from will determine how you care for your bifocal contacts.
Bifocal contacts can be used to correct presbyopia, a vision problem that occurs when the eye loses its ability to focus and it becomes difficult for you to see things that are close. Different types of contacts can help correct presbyopia. Bifocal contacts are lenses with two powers in each lens, while regular contacts can be used to allow you to see in the distance with one eye and up close with the other. Understanding the differences between these two approaches can help you choose the right kind of contact lenses for you.
"Modern contact lenses fall into two categories: soft lenses that are made from water-containing plastics, and GP or 'oxygen permeable' rigid contact lenses," states AllAboutVision.com.
Bifocal contact lenses correct presbyopia, a vision condition that happens to most people between ages 40 and 45. Smaller details become more difficult to see. This happens because the eye's crystalline lens becomes less elastic and does not work as well. Bifocal contact lenses combine both far and near prescriptions to correct for presbyopia. These types of lenses work in several ways, one of which uses concentric rings.
In the past, reading glasses or bifocals were the only options available for those who developed problems focusing on close objects. When bifocal contact lenses were first developed, early versions were not very effective and often led to frustration for many wearers. In spite of improvements and increased options in bifocal contacts, one may still experience problems.
Bifocal contact lenses are lenses designed to correct vision for individuals who have a condition known as presbyopia. Presbyopia often develops with age and reduces one's ability to focus at different distances. Today's bifocal contacts are available in soft and rigid (gas permeable) materials. Bifocal lenses are also referred to as "multifocal" lenses.
For people with certain conditions such as presbyopia, or 'old eyes,' single vision contact lenses cannot correct both near and far vision. As an alternative to foregoing contact lenses in favor of bifocal eyeglasses, many patients have turned to bifocal contact lenses which can correct both near and far vision. These lenses work well in many wearers. However, as with all contact lenses, there are some dangers associated with bifocal contacts.
Bifocal contacts are contacts that have two prescriptions and are needed for people who have presbyopia. Presbyopia affects a person's ability to see clearly when looking at something up close. Bifocal lenses are available as both soft and hard contact lenses. Disposable bifocal lenses are also an option.
