One product from Acuvue for astigmatic patients is Acuvue Advance for Astigmatism. These lenses are disposable ones that can be discarded after a week or two. Johnson & Johnson uses special technologies which take use of the wearer’s blink with the shape of the lenses.

These lenses are not daily disposable that they can be reused after adequate cleaning.

 

People bothered by dry eye can choose Acuvue Oasys for Astigmatism. This special lens option suits astigmatic wearers who spend a lot of time outdoors in the wind or in a dry climate. Using Acuvue Oasys for Astigmatism lenses, wearers can nearly be free from dry eye because these lenses are made to be extra moist. In toric technology, this variety is similar to the Advance design.

Ready-to-Wear Bifocal Contact Lenses

Eyeglasses with thick lenses and a line across them were the only option for people with both nearsightedness and farsightedness. Eyeglass frames were heavy and not only that they were to say the least unattractive. Bifocal Contact lenses were difficult to get used to wearing. Going down stairs especially, you need to look either up or down. While getting adjusted to wearing bifocals some people get dizzy.

People had only one choice if they wore bifocals, eyeglasses. When contacts hit the market bifocals still had to be in eyeglasses. That was then and this is now. Contacts offer as many choices if not more than the choices available for eyeglass wearers. Many people are joyous because bifocals now come in contact lenses. Contact bifocals are available in rigid, soft, and gas permeable materials.

What people need to use bifocal lenses? Those who when focusing on near objects, have trouble. What they have is called Presbyopia. It is unusual for this to develop before the age of 40. Bifocals glasses are similar to Alternating Design because half the lens has distance power and the other half has powers for near objects.

Blended prescriptions for both near and distant vision are Simultaneous Design; they fill in the area of the pupil. Whether you are looking near or far your eye will adjust and learn to interpret the circle power choice. Concentric Design lenses are the radials of contact lenses. The inner lens works on the nearness vision while the outer part works on distant vision correction or vice versa.

Translating Design- these are also very similar to bifocal eyeglasses, the distance correction is above the near correction. The lenses are divided by a line. The lens has a flat bottom so that when you blink it won’t move around in your eye. The center of the Asferic Design lenses is where both the near and distant vision is located.

The center of the lens is where the near vision correction is and it’s surrounded by distant vision correction. In some situations they can be reversed. You can decide this with your doctor. You wear one power lens in one eye and the other in the other eye with Mono-vision Design lenses.

The distant vision is placed in the dominant eye usually. Here again your doctor’s exam will be able to determine this. Simultaneous vision contacts are also available. Focusing on both near and far objects at the same time is possible with these lenses.

Concentric rings form the near and distant correction. Light from both near and far objects can be focused on at the same time since the near and far parts of the lens are in sight all the time.

Simultaneous vision contact lenses have a problem. When the eye is looking through the lens some of the light from the distant objects will enter the distant part and vice versa. The eye, at the same time takes in out of focus and focus.

The brain has to figure out which image is correct. Your doctor must provide you with a subscription for contact lenses not matter if they are bifocal or not. Your eye doctor will do a very thorough exam to decide if you are a candidate for bifocal contacts and what type might be right for you.

Lenses that fit and are comfortable may take time to find, as with any contact lens there is an adjustment. Bifocal lenses may not be for you, at least not in the contact lenses currently available. Don’t give up the search for the right lenses.

Do your research and keep up to date on the types of lenses available to you if you want contacts and need bifocals. By offering a free trial wear period of up to a week, some companies allow you to try their lenses and see if you like them.

Check out discount contact lens stores online and some manufacturers will give you a coupon to put toward the purchase of their lens if you try them. Your decision about bifocal lenses will without a doubt be affected by your budget.

Ask about the experience friends or family have had with contact lenses. You and your doctor can, with this information make a decision but not everyone has the same experience. The option of bifocal contact lenses is now available for people with astigmatism.

Toric contact lenses come in both color and disposable lenses. Some professionals do not like fitting Toric lenses so it is best to check with your eye care professional.

Improving Vision with Bifocal Contact Lenses

Thick lenses with a line across them were the only option available to those who had nearsightedness and farsightedness. The frames for glasses in general were heavy and very unattractive. The problem with wearing bifocals was getting used to them. You need to look either up or look down especially going down stairs. Adjusting to wearing bifocals made some people feel dizzy.

People had only one choice if they wore bifocals, eyeglasses. When contacts hit the market bifocals still had to be in eyeglasses. That was then and this is now. Those who wear eyeglasses may have far fewer choices than those who wear contact lenses may. Many people are happy because now contact lenses come in contact lenses. Contact bifocals are available in rigid, soft, and gas permeable materials.

Who needs to wear bifocal contact lenses? People focusing on near objects who have trouble. The name of what they suffer with is Presbyopia. Over the age of 40 is when this usually happens.

Alternating Design and Bifocal Eyeglasses are alike because one half of the lens enables distance vision and the other allows you to see near. Lenses that try to blend both near and distance prescriptions fill in the pupil area and are called Simultaneous Design. Your eyes will learn to interpret the circle power choices depending on how near or far you are looking.

The radial of contact lenses is the concentric design lens. The inner lens will work on either the nearness vision or the distant vision and so can the outer part of the lens.

Translating design contacts are similar to bifocal eyeglasses where the distant correction is above the nearness vision correction. A line makes the lenses separate. The bottom of the lens is flat to keep it from moving around in your eye when you blink.

Both distant and near vision are located at the center of the Asferic Design lenses. The near correction in the center is surrounded by distance correction.
Sometimes they can be reversed in some situations. You and your doctor can decide that.

With mono-vision design lenses you have one power lens in one eye and then the other power lens in the other eye. Usually the distant vision lens is worn in the dominant eye. An examination by your doctor will be able to determine this.

There are also simultaneous vision lenses. Your eyes can focus on things that are both near and far at the same time. Distant and near correction is concentric rings.The near and far parts of the lens are in sight all the time so the light from both distant and near objects can be focused on at the same time.

Simultaneous vision contact lenses have a problem. The light from the near part of the lens will go through the distant part and vice versa when the eye is looking through it. Both in focus and out of focus can be taken in by the eye at the same time.

The brain has to figure out which is the correct image. Whether contact lenses are bifocals or not, you must obtain a prescription. Your eye doctor will do a very thorough exam to decide if you are a candidate for bifocal contacts and what type might be right for you.

Lenses that fit and are comfortable may take time to find, as with any contact lens there is an adjustment. Bifocal lenses may not be for you, at least not in the contact lenses currently available.

There may be contact lenses out there, don’t give up.Do your research if you really want contacts and need bifocals and keep informed on the types of lenses available to you.There are resources available online, through your eye care physician, and in some cases right from the manufacturer.

There are discount websites for contact lenses and some manufacturers will give you a coupon for their lenses if you try them. Your budget will affect your decision about bifocal lenses without a doubt.

Check with friends and family who wear contacts and see what their experience was like. Although not everyone has the same experience, the information could help you and your doctor make the decision. Bifocal contact lenses are available now for people with astigmatism.

Toric contact lenses come in both color and disposable lenses. Check with your eye doctor about Toric lenses because some professionals are uncomfortable fitting them.

Toric Contact Lens: Specially Designed For Astigmatism

Astigmatism is a defect of a lens resulting in the formation of distorted images; it is caused by the curvature of the lens being different in different planes. This definition of astigmatism may be too professional for common people to understand, but if defined briefly, it is an eye condition and the sufferer may just have slightly blurred vision or have a difficulty to properly focus on or identify fine detail of a shape. Astigmatism can even give you headaches or eye strain and distort blur vision at all distances.

 

Astigmatism is usually a rather frustrating and painful condition, every sufferer wants to find a way to get rid of it. The good news is that there is a kind of contacts that is specially designed for astigmatism: toric contact lens.

 

Toric contact lenses for astigmatism are available in both soft and gas permeable lens materials. The fact is that toric contacts are more difficult to be adapted than those lenses for nearsightedness or farsightedness, therefore the wearer has to try several pairs to obtain the best possible fit, vision and comfort.

 

For the fact that astigmatism will usually cause dry eyes, which is a common condition preventing wearers from wearing contact lenses. To solve this problem, there is also toric contact lens for dry eyes, helping to reduce the harmful and painful effects of astigmatism. The drawback is that those contacts cost much higher that ordinary contacts.

 

One thing needs reminding is that children may have astigmatism as well. It affects a child’s ability to see well in school and during sports, which is very bad for his or her growth, therefore to make sure you schedule an eye exam for your child is necessary.

Custom Contact Lenses: See Clearly without Compromising Comfort

Have contacts always been a problem for you, causing irritation or even pain? If so, don’t give up on the prospect of a glasses-free existence just yet. Custom contacts may be able to help.

Custom contact lenses are like normal contacts that have been designed and shaped specifically to fit your eyes. People with moderate to heavy astigmatism as well as those with otherwise misshapen eyes are great candidates for custom contacts. These patients generally report significantly sharper vision and increased comfort with custom contacts as compared to traditional models.

If you’ve been thinking about giving custom contacts a try, take a few moments to learn the ins and outs of how they work and what they have to offer.

Measuring the Eye

One of the first steps in purchasing custom contact lenses involves very precise measurements of the surface of your eye. Your eye doctor will obtain these exacting measurements with a device called a corneal topographer, which, true to its name, actually maps the surface of the eye by measuring thousands of points on the cornea.

These precise measurements help your eye doctor to understand the unique curvature of your eye and the data gathered will ultimately be used by your contact lens manufacturer to create a lens with multiple curves. As long as the process works smoothly, the custom contacts you receive will conform to each intricacy of your eye, offering a truly comfortable fit.

Types of Custom Contacts

Custom contacts are available in two basic forms: soft contacts and rigid gas permeable (or GP) contacts. Each have their potential shortcomings and benefits.

GP Custom Lenses

GP lenses are also sometimes called hard contacts. Many eye doctors and specialists attest that GP lenses tend to provide sharper, clearer vision on the whole compared to soft lenses. However, some users claim that they are also less comfortable to wear, even when they are custom designed.

GP lenses have a distinct shape in which the edges are slightly tilted upward in order to allow tears to flow behind the contacts when the wearer blinks. This feature provides a healthier flow of oxygen to the cornea, but is a potential source of irritation.

The design also makes it possible for the contact to move around the eye, as its seal against the cornea is not tight enough to hold it in place at all times. Most users contend that it takes a short period of time to get used to the feel of GP lenses while some can’t tolerate them at all.

Soft Custom Contacts

Soft custom contacts, as their name implies, are more flexible than GP lenses. They are exceptionally well suited to correcting astigmatism and have been shown to be more effective than even toric contact lenses, whose main purpose is treating the condition.

Users of soft contact lenses also report a more comfortable feeling in general than with GP lenses. The chemical composition of soft contacts is solely responsible for allowing oxygen to reach the cornea, rather than physical methods.

Drawbacks

One of the most obvious disadvantages of custom contacts, other than extra time spent in the doctor’s office, is price. Because they require meticulous measurements and manufacturing, custom contacts can cost about twice as much as normal contacts. However, the increased comfort of a personalized fit may be worth the expenditure.

Since this type of contact tends to cost so much, it places a premium value on the pairs you receive. In other words, ripping or losing one of these contacts will cost much more dearly than losing a regular contact lens would. The good news, however, is that once measurements have been taken, they remain on record and effective until your eyes experience any physical changes.

Depending on the conditions that have caused a shape irregularity in your eyes, such as astigmatism, you may need to receive follow up measurements in the years following your first exam. However, unless pain and discomfort resurface, this repetition is generally not necessary.

Like all contacts, custom contacts must be cleaned and stored properly and worn responsibly in order to maintain healthy eyes. Wearing contacts for longer periods than prescribed by your doctor, including through the night while you sleep, can lead to the harmful build up of proteins and other substances on the lenses. This build up can eventually or suddenly lead to an eye infection or other complications.

If you’ve been wearing glasses for most of your life and have tried contacts in the past with unpleasant results, custom contacts may provide the answer you’ve been looking for. Because they are designed specifically for your eyes, they offer the bare minimum of irritation. On your next visit with the eye doctor, be sure to ask about how custom contact lenses can change your life for the better.

Finding The Many Kinds Of Contact Lenses

Since the introduction of contact lenses years ago, the eye product has gone through various changes and innovations to meet the needs of the consumers. There are now more than ten types of contact lenses each with its own characteristics. You can get a prescription from an eye doctor and decide on your own which specific brand and type of lenses you want. If you find the task difficult, you can also ask the doctor for his suggested brands and contact lens type. The following are the types of contact lenses you can use depending on your needs and preferences:

Daily wear soft lenses  made of soft polymer plastic, these contact lenses allow oxygen to pass through providing a higher level of comfort than rigid gas permeable lenses. Disposable soft lenses fall also under this category. They are called daily wear contact lenses because they require daily cleaning.  Although most daily wear soft lenses are disposable there are also those that can be worn for one whole year.  Disadvantages of these types of lenses include: easy absorption of oils and lotions from your hand which can irritate your eyes and also less durability than hard lenses

Disposable soft lenses- disposable soft lenses can be worn up to two weeks. They still require daily cleaning but they are not designed to last you months.

Daily wear disposable lenses- daily disposable lenses are lenses which you can only use for one day. They are discarded at days end. Although daily disposables are more affordable than yearly lenses, expenses can add up when you buy a year’s worth of disposable lenses.  Using daily wear disposable lenses lowers your risk to eye infections.

Colored Soft Lenses- Colored soft lenses are perfect for those who want a fresh look. They serve the same purpose as color contact lenses except they do come in different tints. Some colored lenses contain tints not for aesthetic purposes. These light-filtering tinted lenses are for athletes or sports enthusiasts.

Extended-wear lenses- Extended-wear lenses are contact lenses that can be worn for several weeks, usually 30 days without having to remove them. They can come in either soft or gas permeable types. They are perfect for busy people who do not have the time to clean their lenses at the end of each day.

Daily wear rigid gas permeable lenses- these contact lenses are made of plastic that are not as soft or as absorbent as soft contact lenses but they allow oxygen to pass through them.  They don’t tear as easily as soft lenses do but they can take a few weeks to get used to. These type of lenses also require daily cleaning.
Bifocal contact lenses are solutions for those who are suffering from presbyopia.

Toric Contact Lenses- this type of lenses are used to correct astigmatism.  These contact lenses are also bi-focal. And can be made from soft lenses or gas permeable materials.

Orthokeratology lenses- these lenses are used for improving vision problems caused by the cornea’s shape. These lenses when worn overnight adjust the shape of the cornea so that the individual can have food eyesight the following day for up to 12 hours.

Looking For Biomedics Toric Contact Lenses? Get Biomedics Toric Contacs Cheap

<!– @page { margin: 2cm } P { margin-bottom: 0.21cm } –>

Biomedics toric contacts are specially designed for people with the eye condition astigmatism, which is a misshaped (football shaped) cornea or optic lens. A toric contact has two different powers or curvatures so that it can rectify both astigmatism AND either myopia (near-sightedness) or hyperopia (far-sightedness).

More and more, toric contact lenses, which normally blend the effects of a cylindrical lens with that of a spherical lens, are being prescribed for people who are astigmatic (i.e. have corneas that are shaped like footballs) and also require assistance with their distance or near sight. These are people who who might have been told in the past that they were not suitable candidates to wear contact lenses.

It is possible to have astigmatism in only one eye. In such instances, the eye doctor may prescribe a toric lens for one eye and a regular spherical lens for the other eye.

Toric lens are available in soft or rigid gas permeable like regular contacts. BUT unlike regular lenses, which have the same focusing power all around so that it is not an issue if they rotate on the eye, torics are not spherically symmetric and have a definite “up” and “down” position they must maintain in order to be effective.

This means that a toric lens MUST keep the same position irrespective of eye movement, otherwise visual acuity is impacted. Toric lenses are usually kept in place by making the bottom of the lens ballasted (slightly heavier and truncated). The ballasted portion is pushed into the correct position when the upper eye lid blinks.

Biomedics toric contact lenses for astigmatism are more expensive than regular spherical contacts because of the time and expertise involved. Additional expenses are also incurred at the manufacturing stage because each lens has to be custom made for the patients vision correction needs.

You now have the same range of formats and materials available for toric lenses compared to regular spherical lenses. Previously only rigid gas permeables (rgp), a special type of lens that allows more oxygen to reach the eye, were available for correcting astigmatism. Today torics are available in daily wear, disposable, color (to enhance or completely change eye color) and rigid lenses.

Generally people prefer soft contacts over RGP because of the ease of handling and are more comfortable. The benefit of RGPs is that they tend to retain their shape on the cornea much better than soft lenses and usually provides crisper and clearer vision for astigmatics.
