Trifocal Eyeglasses and Contact Lenses

September 25, 2011

As we grow older and reach closer to forty our clarity of vision is compromised gradually. Presbyopia is inevitable as we cross the age mark of forty. however, there is nothing to worry about. with constant advances in technology and science spectacle lenses and contacts are becoming more and more progressive. they offer maximum comfort at competitive price ranges so that the average person can save himself or herself the annoyance of having lines across his spectacle lenses.

Those suffering from the condition of presbyopia have three problems:

1.Close range focusing
2.Distance vision
3.Intermediate clarity

This is where we introduce the concept of trifocals. Bifocals have ruled the scene for quite some time now. however, with three sorts of range problems in vision due to presbyopia trifocal lenses deal with each of them separately, correcting them progressively.

Spectacles made of trifocal lenses do not have any demarcations on them suggesting the condition of presbyopia. Therefore, wearing these lenses is perfectly normal. If you want to personalize the spectacles according to your style and taste you can always choose a nice frame to suit your face.

Reading glasses are recommended to many patients as part of short distance vision correction. This is all very well until you start having problems with intermediate range as well. Carrying reading glasses and putting them on while focusing on near objects and then changing into your bifocals can be a tedious process. Trifocals are the best option in such a case. with progressive lenses there is no fuzziness of vision. These are also known as varifocals, power progressive lenses or graduate lenses.

Contact Lenses with Ring Correction

If you don’t want to use spectacles on a day to day basis you can always opt for contact lenses. no longer do you need to wear hard contacts for presbyopic vision. The discomfort associated with such lenses is high.

Contact lenses are made specially to suit the needs of patients suffering from all three kinds of vision problems mentioned above. Such contact lenses are constructed with separate rings demarcating the vision correction according to the distance focused on. In case of close objects you look through one region of the contact lens made with a specific technology. In case of distance focusing you look through another region of the lens made with a different technology.

In case of presbyopia if you have a power of -4 diopters and the corrective power prescribed for you is +3, leaving you with an additional -1, the intermediate range correction becomes -2.5 diopters. due to progressive lenses you can wear spectacles with smooth lenses as well as contact lenses to avoid having specs resting on the bridge of your nose.

If you want neither you may opt for LASIK surgery. This is a form of corrective eye surgery that deals with the smoothness of the tissues on the surface of your cornea. Although this is a permanent corrective procedure, the presbyopic symptoms may recur after 10 years.

Coloured Prescription Lenses

August 9, 2011

Coloured contact lenses have become increasingly popular in recent years and it is even possible to get them in prescription format. what exactly do we mean by that? Well, a prescription lens is one that corrects your eyesight, in the same way that glasses do. A coloured lens is a type of contact lens which is tinted, or which has a design on it. A coloured prescription lens, therefore, is a lens which is not only tinted, or has a design, but which also lets you see properly.

Now that coloured lenses are available in prescription strengths, everyone can enjoy the possibilities afforded by these little items. Items which not so long ago would never even have been considered as a fashion accessory. Now you can match you eye colour to your outfit, or to one of your other accessories. or perhaps you just fancy having different coloured eyes today. Well, now you can, and if you need glasses or contact lenses to see, you’ll still be able to see, thanks to coloured prescription lenses.

What sort of colours are available? Various shades of blue, green and grey are probably the most common and the most popular, but if you want something more unusual then you’ll be able to find black red, white. just about anything, in fact. A word of warning here: If you decide to venture more into the world of novelty contact lenses then you’ll find it much harder to get hold of them in prescription versions. of course, if you wear lenses with no strength, also known as plano contacts, then you could always wear your glasses on top. whether this defeats the object of wearing coloured contacts is something you’ll have to decide for yourself.

Experimenting with all the different colours and designs can be a lot of fun, not only for you but for the people who see you. But don’t get carried away. Your eyes are delicate organs and it would be foolish to take risks. If you already wear prescription lenses then you’ll already know about how important cleanliness is when handling contacts. Exactly the same applies to coloured lenses, prescription or otherwise, and on no account should you be tempted to share your coloured lenses with your friends. It is very highly recommended that you seek the guidance of your usual eye specialist if you are thinking about wearing these lenses, as he or she will be able to advise on whether these are suitable for your eyes, and on which brands would be best for you.

Enjoy your coloured lenses, but above all, don’t take risks.

Optical Swimming Goggles for the Shortsighted and Farsighted

August 1, 2011

At last there is a way for those of us who wear contact lenses or glasses to see safely and clearly when swimming. Optical swimming goggles designed specifically for the farsighted and nearsighted have all the features of regular swimming glasses, but with the advantage of ensuring perfect vision. they are manufactured in a wide range of various positive and negative diopters.

Good vision is just as important in the swimming pool as it is anywhere else – whether you are just splashing around in the pool while on vacation, or you are a serious competition swimmer. People who sail or play other water sports such as windsurfing and skiing can also benefit from having prescription goggles.

Surprisingly, swimming goggles are not a new invention – during the 14th century, Persian divers used protective goggles made from the polished shells of tortoises. Swimming goggles as we know them today were devised in the early 1960s and the basic design has been improved upon over the last 40 years, as technology has improved. the widespread popularity and increased use of swimming goggles during the 1960s and 1970s led to many swimming speed and distance records being broken.

Not only do goggles help you to see more clearly underwater, the range of colors and styles available have helped them to become a stylish accessory. Optical swimming goggles today come in many different styles, colors and prescriptions. Swimming goggles offer a wide range of strengths making them suitable for both shortsighted and farsighted users. there are also prescription goggles specially designed for children.

Apart from the wide range of styles available, there are also different tints and colors of the lenses themselves. Blue or green tinted lenses help protect the wearer from bright sunlight, while yellow colored lenses can seem to make indoor light appear brighter. Clear swimming goggles are suitable for night swimming and also for use in indoor pools.

Swimming goggles have health benefits too – they can protect your eyes from the often harsh chemicals found in many swimming pools. they can also help to protect eyes from potentially harmful micro-organisms and bacteria in the water.

Wearing prescription goggles is particularly important if you wear contact lenses. Although most people are able to swim with contact lenses, the Center for Disease Control found that swimmers who kept their lenses in faced more health risks, as well as the risk of eye infection.

And of course you take the risk of losing your lenses – studies indicate that about 10% of swimmers who regularly swim with their lenses in will sooner or later lose one or both of them. another benefit of wearing goggles!

As far as comfort goes, ideally, goggles should feel comfortable and fit snugly over your eyes – if you routinely do a lot of diving, the goggles should be a little bit tighter in their fit, to help prevent them from being dislodged.

There is no doubt that optical swimming goggles have come a long way in the last 40 years or so – today’s goggles are not only stylish and functional but have features such as anti-fog coating, ultra-violet protection and are long lasting and shatter proof. Clear and safe vision in the form of prescription goggles is now readily available to all – perhaps the most useful invention since the swimming costume!

Can I use my glasses prescription for contact lenses?

June 20, 2011

I really want contact lenses instead of glasses. unfortunately, the last time I got my prescription updated (a year ago) I only paid for the glasses eye exam, not the contact lens exam (I guess they're different.) I really don't want to pay for another eye exam but I do want contact lenses. can I use my prescription for contacts?

Generally, the on-line contact sites will not sell you contacts unless you have a valid prescription for contacts (less than 1 year old). they are supposed to verify this, this is the law (at least in the US anyway). I suppose it is possible you find some fly-by-night web site that will sell them to you without the proper prescription.

But, how do you know that both prescriptions would be the same ?

Over 85 % of the time, the contacts prescription will be a bit different than the glasses prescription.

Also, what about the base curve of the lenses, and how do you know which brand will work best for you ?

A real contact lens prescription will have all that info that you would need to order contacts.

No, a exam for glasses & contacts are two different exams. when they do the exam for contacts they check the fit for your eye which is called a base curve & they have to tell you what kind you can wear, ANYBODY that you order from will contact the place you got the exam to make sure your information is correct ( It's the LAW)

No for two reasons i'm aware of.
1. you will not have your pupil diameter for contacts on that prescription
2. glasses sit in front of your eyes but contacts are on your cornea so they need a different prescription.

Good luck

Multifocal – Progressive Glasses Online

June 19, 2011

Multifocal glasses are prescribed to people who have more than one vision problem. Bifocals are the most popular form of multifocal lenses. Bifocals allow people to see things in the distance as well as close up. People who wear bifocals often have to wear their glasses all the time. Bifocals were invented in an effort to eliminate the need of purchasing two separate pairs of eyeglasses and switching back and forth as a person changed activities. More than half of the people who wear eyeglasses wear bifocals. Bifocals are prescribed for people with presbyopia which is a condition that usually begins in the 40′s and stems from the gradual loss of the natural flexibility of the lens inside the eye.

Another form of multifocal glasses is trifocals. Trifocals are eyeglasses that have lenses that can correct three forms of vision problems. these lenses correct near, distance, and intermediate vision problems. Trifocals are a popular type of eyeglasses for computer users, who may need clear vision at a distance, for reading, and for seeing the computer screen. these types of lenses are most often prescribed for people in their 50′s. Trifocals are most often used to treat advanced presbyopia, a natural progressive eye disease.

In the past, multifocal glasses were expensive, and many people who actually needed these types of lenses could not afford them. And, when they could afford them, they often found it distressing if the glasses got broken or were lost. Replacing the eyeglasses was not always in the budget, especially when they cost upwards of $200 per pair. now, however, there is another alternative that allows people, no matter what their budget, the ability to purchase the eyeglasses they need for clearer vision.

If left untreated, vision problems can progress much more rapidly than when someone uses corrective lenses. Online retailers have provided a way for people to purchase affordable eyeglasses, including multifocal glasses, at a fraction of the cost of brick and mortar retail stores. The reason is simple: less overhead means savings projected onto the consumer. in many cases, the cost is only a fraction of what you would normally pay for a pair of glasses, which often results in allowing a person to order more than one pair of glasses so that should their glasses get broken or lost, they are not left in the dark. The Internet has given us many advantages, including allowing consumers to benefit from purchasing products from retailers that have less overhead, which means less markup from the wholesale price and more savings and options for the consumer.

After getting glasses is it possible to have better than 20/20 vision?

June 19, 2011

After I got my glasses, I used an eye chart (the one with all the letters that get smaller and smaller), and my vision without glasses (and contacts actually) was the same as the doctor said. And when I put them on, my vision is higher than 20/20 (like 24/20). Is this possible? or is the eye chart screwed up?

A higher number is worse vision. If you can read the line below the 20/20 line, then you have 20/15, which is very good. The next line is 20/10 which is spectacular vision.

20/40 is the worst vision you can have and still drive without corrective lenses.

NO !
It is impossible but if you go back to school , you can increase greatly you IQ and understand why …..

Contact Lenses Vs Glasses – Which Provides Better Vision?

June 14, 2011

The debate of whether contact lenses or glasses are the better way to see is a debate that has been ongoing for quite sometime. some individuals detest contacts because they could never imagine ‘putting their finger in their eye’ and others claim that contact lenses are better because the person’s vision is not restricted to the rim of their eyeglasses.

Glasses have been around in some form for quite some time. To be exact, it is the 8th century B.C. in which some kind of lens was used to help those with vision problems. It was the 1st century B.C. in which recorded history claims that individuals were using emeralds to see better because of the magnification they produced.

Fortunately, we’re not using emeralds to see nowadays. The restriction of eyesight is hard to imagine when using a method to see what’s in front of you. However, still today individuals feel that they are held prisoner by their glasses because they can only see so much through the lenses.

At one time, the frames of glasses were very large, so a person’s overall vision was not too bad. The only issue was looking left and right. In other words, peripheral vision was not very good. even today peripheral vision with glasses is not something that is a luxury. Glasses have become smaller in order to stay with the styles and now the actual seeing surface is even smaller. Many feel that their eyeglass options have been significantly compromised with these smaller frames because they feel they have to look straight ahead at all times to see.

Contact lenses give a person the illusion that they don’t have corrective lenses. You can’t feel them, others can’t see them unless they look at your eyes closely, and contacts open you up to an entirely new world.

Being that they rest directly on your eye, you can see all around you without having the barrier of your rim ruining your peripheral vision. You can look up, down, left, and right and be able to see the world. That is something that is not done by glasses. The one thing that is different is that contacts do have to be placed onto the eye, but there have been changes in the contact lens industry such as the development of contacts that can be work non-stop for 30 days. This means being able to sleep in them, giving the illusion when you wake up in the morning that vision problems do not exist for you.

There are advantages to glasses over contact lenses just as there are advantages to contact lenses over glasses. Unfortunately, contact lenses are not able to correct near or farsightedness while correcting astigmatism, so many have to deal with astigmatism while correcting the near or farsightedness. there are contacts made for astigmatism, but that’s all they do; correct the astigmatism. Glasses can correct multiple vision problems in a single lens.

However, glasses do cause you to not see things for what they are. Sizes and colors of things may look different. With contact lenses. you see the world for what it really is. That means you should weigh the pros and cons before making a decision. if you can deal with the small cons of one or the other, then you have your answer as to what you should do to correct your vision. even if you have never worn contacts, it is never to late to try them in order to decide if they are what is right for you and your vision.
