The different contact lenses materials and what they do.

The different contact lenses materials and what they do.

The different materials that your contact lenses are made from is affecting how they wear in a lot of senses of the word, including how long they last, your comfort and their health impact.

For a lot of years contact lenses were made from glass. Today, less than 1% are, with the other 99% made of various sorts of plastic. The selections are generally some kind of PMMA ( polymethyl methacrylate ), polycarbonate or silicon hydroxy gel. Hard contact lenses introduced in the 1960s are made from PMMA and do not permit oxygen to move without delay thru the lens, but some air does reach under it any way. When an individual blinks the lens moves a touch and some air diffuses thru the tear solution that covers the eyeball. Soft contact lenses, first introduced in 1971, were made from a polyacrylamide containing nitrogen ( hydroxyethyl methacrylate or HEMA ) which made them what is named 'hydrophilic'.

At the same time, they are a touch more permeable to air than their older cousins. RGP ( Firm Gas Permeable ) lenses are midway between a truly hard lens, like glass or PMMA, and a soft lens. They mix PMMA with silicone and fluoropolymers that let air to get to the eye. That increases your comfort and decreases the percentages of health issues due to long term wear. Extended wear lenses, which come in anywhere from 2-day to 7-day to even 30-day use models, are made from silicon hydroxy gel. That material permits up to 7 times the quantity of oxygen to pass thru the lens, giving the chance to wear them lengthier compared to others. They can be worn daily for a week or 2 and removing them each night is a choice. The majority are engineered to be worn steadily then simply disposed of. Made of a mix of a polymer called etafilcon ( 42% ) and water ( 58% ), they are extraordinarily thin, flexible and have excellent gas permeability. Disposables are particularly favored among sports enthusiasts due to the fact that they fit near to the eye, making them awfully not easy to dislodge.

They are also extremely comfy, so they can be simply ignored during activity. However, many don't offer quite the level of crystal clear vision as other types, so they are not acceptable for everybody. Also, they do not correct some vision issues and other types, which boundaries their use for some. Except for the choice of material and wear traits, there are a few options today in contact lenses that simply did not exist twenty years back. Single vision lenses are like two glasses worn near to the eye. Today, bifocals in contact lenses are possible. Even multifocal or progressive lenses are a choice. These help compensate for presbyopia, a kind of farsightedness that is affecting virtually everyone as they age, sometimes beginning in the mid-40s. Research your options and you will shortly find contact lenses just suitable for you and your way of life.

Lasik Surgery

An alternitive to Lasik Surgery could be natural vision correction

Today more and more people are choosing Lasik Surgery as an option for improving their eyesight.  This may be a good option for you; but it's always best to know your options, the risks, and anything else that might help you make this decision.

When considering your Lasik Surgery procedures here are some things to consider;

There is time needed for recovery-pain is a typical occurrence.  Most cases are mild to moderate pain.  This is often controlled by prescription pain medications in some cases.

The time you take to recover, may leave you with blurry vision; this can take a few days in some cases.  In older individuals, you may still need your glasses for a few days after surgery while you heal.

It may be good to know that it's not always successful.  Sometimes, the procedure doesn't work and you could regress back to the state you were before the surgery.  In this case it's good to know your chances before proceeding.

Not a permanent fix; sometimes it lasts only for a time period.  As we get older the need to wear glasses or contact lenses may return.  Those over 40 will likely have this occur.

What should I do?

Talk to you doctor; this is a good place to start.  Make sure he/she informs you of all that it entails.  Don't be sold on a sales pitch; you want a doctor who is going to benefit you, not look at you as the next payment on his car.

Research your options.  Knowledge is power-so it is said-you can feel better when you weigh the facts.  Get some concrete literature on the process, what it entails, anything that will give you a clear and unbiased and informative view of the procedure and what you as the patient can expect.

Talk to people; if you have questions, it may be of help to talk to people who've had it done.  Get some feedback.  Not all cases will be the same, so keep that in mind.  It is however, a good idea to know the facts, whether they're good or bad.

Overall, the Lasik surgery process appears to be helping many people annually see things more clearly.  Although it's not for everyone, if it's something you are thinking about, get informed before you make the leap.  Be sure to ask questions even if they seem silly.  Your best source of information is your doctor, don't be shy when asking questions, this is your sight, and it's in his/her hands.  You have the right to know.

Talk to your doctor and do your research, then you will have a better idea of your options before you take this step in sight improvement.

2. Breath- Breathing sounds very weird as a solution for the eyesight weakness because usually everyone thinks that what connection could be there between the breath and eyes. But as per the medical sciences reports, eyes are one of the major oxygen consuming parts of the body.  There are persons who do not breathe properly and comfortably and hence faces eyesight problems and their eyes problem can be resolved as soon as they start breathing properly and adopt it as a habit.

3. Targeting- Targeting here does not mean that practicing on the target board, but it means focusing on the tiny things through which one gains the ability to focus.

This will increase the ability to focus and shift the sight at a glance.

Vision Care and Cataracts

Are you or does someone you know have any of these symptoms?

" Cloudy, fuzzy, foggy, or filmy vision
" Loss of color intensity
" Frequent changes in eyeglass prescription
" Bright lights causing a glare and vision problems at night
" Increased sensitivity to glare from lamps or the sun
" Double vision
" Decreased sensitivity to colours and shades

These are some of the common symptoms people have when they are dealing with cataracts.  These are reasons to see your doctor or optometrist regardless of the time.  Any changes to your vision require attention. 

Cataracts affect thousands of Canadians each year.  It's a debilitating and hard thing to deal with, yet there are ways in which you can treat them.

What are cataracts?

A cataract is a cloudy area that lies within the lens of the eye. Normally the lens would be clear, but this cloudy covering can interfere with your vision and day to day life and needs the attention of a professional to take care of it.

Cataracts are rarely seen in infants or children.  It can however be congenital, which means it may run in the family.  Cataracts form often in adulthood, and can be caused by a number of things.

Some of the things that can cause cataracts to form are; certain medications, diabetes, infections, metabolic diseases, among other factors. Cataracts are treatable, but it is something you need to see a professional about.

Your doctor may order some tests to be done to help determine you're visual concerns.  He/she may order a Glare Test or a test to test Contrast Sensitivity.  There are other tests which they may determine to do, depending on your individual needs.

The need for surgery comes when 'normal living' becomes and issue.  This surgery is usually done as an outpatient procedure and does not necessarily require general anesthesia.  Although, for minor cases there may be some treatments your doctor will be able to try such as; a change of glasses, or using a magnifying lens, not cures, more of an alternative.  Many choose the surgery to reap the benefits of clearer vision again.

Although cataracts can be a nuisance and can hinder life, this problem is one your doctor sees often; he or she will ensure you are led through the process of regaining your sight and your independence once again.


Again, when you find that your sight isn't what it should be, see your doctor.  Your best chance for making it better is 'seeing' it through, not ignoring it.

See your doctor and you will see things in a whole new light!

The Eyes Have It. They Are More Complex Than Any Computer In The World

The eye is made up of so many parts. Like a camera, what we see from the outside is only a simple picture to what lies beneath. The overall function and design of the eye is much more than just a white ping-pong sized ball with a colourful space and a little black dot. Your eye is the window to the world. It takes thousands of 'calculations' so to speak. What you see is only a small part of the overall picture. The following is a summary of each part and its function.

Check out our site for Vision Care


Part Description Function

Eye socket Hollow space/opening Holds and Supports the function of the eyeball itself

Eyelid Skin over eyeball This skin through muscular automatic and voluntarily movements. It acts in this capacity to help keep the eyeball moist and to keep it clean and free from debris.

Eyelashes Tiny hairs framing at the end of the eyelid. The lashes although decorative are there for much more than holding mascara. Lashes work to catch dirt and minimized it's entrance to the eyeball.

Eyeball Ping-pong sized white part of the eye. The white part of the eye is made up of a tough material called sclera. It covers a huge part of the outer covering for the eye. The eye has noticeable tiny pink threads, (Blood Vessels) which deliver blood to the sclera.

Cornea Clear/Transparent dome. This dome sits in front of the coloured part of the eye. It help the eye focus as light passes through.

The Iris The Coloured Part. Controls how much light goes through the pupil

The Pupil The Little Black Dot Set in the center of the eye, the pupil is actually an opening into the inner parts, the size of this black dot is dependent on the amount of lights it's exposed to.
When the dot is smaller, it's due to brighter light, thereby minimizing the amount of light that enters. When it's larger, this is due to a darker area, in opening, it allows more light in, so you can see a little better in the dark.

Anterior Chamber Not visible. The space between the cornea and the iris. The transparent fluid is there to nourish they eye.

Retina Not visible. Processes what the eye sees. It receives the signals or information which is sent to the brain for understanding.
Your retina is at the far back part of the eye that takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing.
It uses cells called rods and cones to process light. In all there are about 120 million rods and 7 million cones per eye.

Lens Not visible. Like a camera, the lens processes and captures the image. It is held by fibers which are attached to muscles called ciliary muscles. It actually changes the size and shape of the lens.

Vitreous Body Not visible. This sits behind the lens, and forms two thirds of the eye's volume and gives the eye its shape. It's filled with a clear, jelly-like material called the vitreous humor.
Rods Not visible Works the processing of black, white, and shades of gray.

Cones Not visible. Work to process colour. They only see colours. They are most sensitive to one of three colours; red, green, or blue. Together they are able to differ what they see to form millions of other colours. Those without functioning cones experience colour blindness.

Optic Nerve Not visible. Acts as the messenger in the back part of your eye. It carries the information it sees to the brain for understanding.

Lachrymal Glands Tears. These glands produce tears for flushing foreign bodies from the eyes. This fluid is regulated by blinking.
Your eyes do so much; protect them and SEE how great they really are!!

Implantable Contact Lenses Are An Excellent Alternative to LASIK Eye Surgery



Implantable Contact Lenses Are An Excellent Alternative to LASIK Eye Surgery

Not everybody is an acceptable prospect for LASIK eye surgery There is however an alternative to lasik surgery.

A common alternative to LASIK surgery are Implantable Contact Lenses, also occasionally referred to as a permanent contact lens or ICl. An ICL is a soft lens that's affixed to the eye for correcting nearsightedness. An Implanted Contact Lens is meant to be lasting, but it could be replaced if changes are called for in the future. Contrary to  LASIK eye surgery, the ICL operation is totally reversible.

In that respect there are definite advantages to ICL over LASIK. For instance, with LASIK eye surgery, permanent alterations are made to your eye and those alterations are something you will have to live with. If everything went well with the LASIK procedure then clearly there is no issue, however occasionally it does not go as hoped and as such you're stuck with it. In complete contrast, Implantable Contact Lenses may removedt at any time if rectifications are required.

If you have previously worn contact lenses, you already live with  the bothers of normal contacts - cleaning, soaking, removing and replacing, etc. But with implantable contact lenses, all those annoying tasks immediately disappear. The implants are lasting and ought never need any tending unless your vision changes as you age. Implantable contact lenses offer the same vision improvements as normal temporary contact lenses, only they call for none of the attention and upkeep of standard contact lenses.

The ICL routine is generally executed on an outpatient basis and you will feel little or no pain. A gentle sedative is dispensed to provide a calming effect and a 1/8 inch surgical incision is created for insertion of the lens. When inserted, the lens is properly positioned. In virtually all cases, sutures are not needed to close the incision point. If you are getting the operation performed on both eyes, they will both be accomplished in a single session. The whole process is normally accomplished within about 30 minutes.

Upon completion of the ICL procedure, you will be directed to a 'post-op' area for recovery. When staff members ascertain that you're stable, you will be sent off home to unwind for the rest of the day. You will need to come back the following day for a follow-up exam, just to make certain that everything is alright.

On that point may be some mild haziness upon completion of the implantation, but this typically clears itself within a brief time period. Most patients experience fast improvements in vision, with approximately 90% of normal vision restored within the first 24 hours. Usually, your vision on the second day will be good decent to allow you to drive yourself to the examination.

The primary issue of worry with implantable contact lenses is the risk of infection. Once detected it will be sorted out, so it is important to keep in touch with your medical team.

Implantable contact lenses are a sensible alternative to LASIK eye surgery for patients who have trouble with distance vision. Notwithstanding this , ICL does not help you if you require reading glasses.
