Have your child’s grades dropped at school ?

August 2nd, 2010

Confession of an Optometrist

Vision and learning – my story!

Aged 10, I had always been one of the “clever” students in school. Aged 11. my grades were slipping, I was falling behind other students in my class, was having difficulty staying focussed and  was struggling  to pass tests I would have aced before. The reason? Increasing shortsightedness and astigmatism meant I couldn’t see the board, was taking longer to read, needed to hold my books almost up to my face and could barely read the expression on my teacher’s face. I knew my vision was poor but didn’t want to wear glasses. However when my cover was finally blown by the  public health nurse, and I was made to get the dreaded spectacles, it was a relief to finally have my world in focus. My grades improved dramatically again.

If a child is struggling in school, it is vital to rule out problems with vision. But not all problems will be picked up in a school screening. A child may have excellent distance vision but be unable to focus up close or may have difficulty with eye movements which slow down reading and impact on the ability of the child to keep up with his or her peers.

An inability to make both eyes point in the same direction can make the words appear to jump on the page. A full eye examination by an optometrist who specialises in childrens vision will uncover problems like these.

It is gratifying as an optometrist to be told that a child in your care has come on in “leaps and bounds” in school since getting their new spectacles. And I do envy today’s children the lovely frames available to them, with characters like Hannah Montana and Sponge Bob all bringing out their own trendy ranges. It is important that the frame should fit well; a badly fitting frame will be uncomfortable and will cause it’s own problems.  We are lucky in Mairead O’Learys to have  excellent dispensing opticians who will check the frame to make sure it is a good fit as well as being super-cool!

Sometimes glasses on their own are not enough and a child may benefit from Behavioural Optometry or Vision Therapy to enable them to learn to use their eyes efficiently. Having become interested in this area some years ago, I now run a small clinic, specifically for children with learning difficulties. Most do improve after a few sessions, including home exercises to do between sessions.

If your child is having difficulties in school, please contact us in Blanchardstown to arrange a full eye examination.

Why buy your glasses where you get your eye test?

July 24th, 2010

It’s nice to go back to the same person for your eye test every time.  Most people tend to stick to the same optician that they know and trust when having their eyes tested.

In the current economic climate, it’s tempting to shop around when buying their glasses in the hope that you will find the best deal.

The problem arises if you have difficulty getting used to your new glasses. If you get your glasses in a different place, it’s likely that they will blame any problems you have on the prescription you obtained elsewhere.  This means that you may have to return to the original practice to try and find the source of the problem.

Even if only a minor adjustment in the prescription is needed, it is difficult for the first shop to change the glasses, as you’ve paid somebody else to make them.

If you get your test and glasses from us, we will take a lot of care to make sure that you won’t have any problems with your glasses.  We’re more than happy to help you through the whole process, and make sure that you leave us totally satisfied with your experience.

We have been in business for 22 years and wish to thank thousands of loyal and regular patients over those years. Out motto is “Service for Life”.

That is our commitment to you.

Laser Surgery : An independent view

July 5th, 2010

What is it ?

In the last two decades the number of people who have had laser treatment to correct their eyesight has risen sharply. Laser surgery involves reshaping the front surface of the eye, the cornea, with a specially equipped laser in order to improve vision. Treatment is available for long-sighted, short-sighted and astigmatic patients. However, there are limits to the degree of each condition that can be treated with the laser. If your prescription falls outside the “treatable” range for laser surgery alternative surgeries may be suitable.

What’s the difference between LASIK and LASEK?
In LASIK:  a thin layer of the cornea is lifted back after being cut with a machine called a microkeratome. Then, the laser is used to reshape the internal cornea. After the tissue has been reshaped, the flap is replaced in its original position and heals quickly.

In LASEK: a thin superficial layer of corneal cells is removed and the tissue beneath is treated with the laser. Unlike in LASIK, there is no “flap” created. After laser treatment, the cell layer is replaced and the eye covered with a bandage contact lens to allow it to heal. This method allows higher levels of myopia to be treated than LASIK. However, this treatment takes longer to heal and often provides more discomfort than LASIK.

If I have Laser Can I Throw Away My Glasses Forever?
The most likely answer to this question is No. If you are under 45 and have laser surgery to correct your vision to “20/20” or as close to perfect as possible in both eyes, you will need reading glasses from your mid 40’s or 50’s onwards. If you are over 40 and have already developed a reading prescription or remove your glasses to read, then having bilateral laser treatment may mean you will need a spectacle correction for either distance or near.

I’ve heard people talk about monovision, what is this?
From mid 40’s onwards people develop different distance and reading prescriptions – see Presbyopia. Correcting both eyes with laser treatment to make them “perfect” for distance means that reading glasses are necessary. Correcting both eyes so that they are “perfect” for reading means that distance glasses will probably be needed. In Monovision  – one eye is corrected for distance vision and the other for near vision. In some cases this is achieved by performing laser on one eye only and leaving the other eye in it’s natural state.

When this works, it means that reliance on glasses for both distances is done away with. However, having two eyes focussing together and corrected for the same distance is what gives us binocular vision and gives critical depth perception.
Monovision does not work for everyone, some people will be aware of visual confusion as the eyes are focused at different distances and / or that judgement of depth is impaired. This is an important consideration for those people for whom critical depth perception is required in their occupation or hobbies. Often a trial with contact lenses to simulate monovision will be offered and patients can assess for themselves how comfortable they are.

Monovison may work better for early presbyopes with lower reading prescriptions, hence the success and comfort obtained in the first number of years after treatment may not be maintained over time.

Laser Surgery has brought freedom to many spectacle wearers, however, it is a surgical treatment and as such, carries risks. Many laser clinics have opened in Ireland over the past decade and anyone opting for the treatment should be confident and comfortable with the clinic they choose. As some clinics do not perform surgery on a daily basis, the surgeon may only attend once or twice a week and in some cases may fly in and out to carry out the scheduled surgeries. Before you decide where to have laser treatment or indeed if the treatment is suitable for you ask the following questions.

- Will I meet the surgeon before I am booked in for treatment?
- Is the surgeon available 24/7 should there be any complications?
- Am I likely to need glasses again and if so in how many years?
- How long has this clinic been carrying out procedures and how many patients have been treated?  What percentage of them needed additional treatment?
- If I need a “top-up” treatment, do I have to pay for it?
- If I am comfortable with monovision now, is it a guarantee that I won’t need spectacles again?
- I have dry eye, is this likely to cause me additional problems after surgery?

Eye bag – success

June 26th, 2010

Its not often one would blog yet again about the eyebag, but the reports coming back from patients are just brilliant.

I suffered myself for a short while from a gland problem and my eyes were irritated and red. Washing with Johnstons baby soap was the answer and hot cloths were messy and cooled down quick.

So the answer is the eyebag that you popin the microwave and give your eyes a real treat.

How it works!

When placed on the upper face, the eyebag gently releases warmth which stimulates the normal glands around the eyes, releasing the body’s own natural oils, giving you instant comfort.

Our eyebag could be just what you are looking for. The EyeBag was created in 2004 by Mr Teifi James, a consultant Ophthalmic Surgeon, working in West Yorkshire a patented, CE marked Class 1 medical device registered with the Medicines and Healthcare products Regulatory Agency (MHRA).

The heated EyeBag is applied to the upper face so that the bridge of the nose and both the upper and lower eyelids are covered, will release warmth; stimulating the normal sebaceous oily secretions from the meibomian glands and offering instant comfort.

Watch this video referencing the success of the Eye Bag from a consultant Opthalmologist. 

In stock today in both Rathmines and Blanchardstown.

How do varifocals work ?

May 23rd, 2010
  • The top part of the lens has your distance prescription, so when you’re looking straight ahead, everything is clear far away.
  • There’s a gradual change in the prescription from distance at the top, to reading at the bottom.
  • Slightly below eye level, you have an intermediate prescription for computer use.  Your computer must be below eye level for clear vision with varifocals.
  • Unlike bifocals, in they have no dividing line on the lens, so nobody knows you’re wearing them.
  • Because all the powers are blended together in the one lens, there are distortions at the sides of the lens, so just a central channel in the lens is clear.
  • Better quality varifocals have significant less distortion.  They’ll give you more area for doing things, and are easier to get used to.  It’s worth investing in good quality lenses, so you’ll have more comfort with the glasses.
  • They take up to two weeks to get used to, but once you realise how convenient they are, you’ll never look back… no more taking glasses on and off, and swapping between pairs!

Is short-sightedness genetic ?

May 15th, 2010

Not necessarily!

A study done was done in the past by Dr Young in Alaska.  He checked the vision of 130 Eskimos who were being introduced to American society.  The parents were illiterate.  They did outdoor activities like hunting, and hardly any close work.   Only 2 people out of 130 (1.5%) were found to be short sighted.  The 2 that were, only had a small amount of myopia.

Their children were all sent to mainstream education and so would have been doing a lot more studying and close work.  More than 60% of the children were short sighted!

Children with myopic parents are more likely to be myopic.  This is partly due to genetics, but could also be because of parents and children having similar lifestyles and levels of education.

Help I have hay fever !

April 16th, 2010

I love the smells of spring but every year it brings on hayfever!

Hayfever is an allergic reaction to pollen.  As well the usual symptoms such as stuffy nose and sneezing, your eyes can also be affected.  They may get red, watery, and very itchy.  This can be extremely irritating, but you may find some of the following tips helpful.

  • If possible,  stay indoors when pollen count is highest (morning, and early evening)
  • Close windows to avoid letting extra pollen in
  • Wear glasses or sunglasses when outside to keep air out of your eyes
  • Avoid wearing contact lenses when you’re having symptoms
  • Antihistamine eye drops such as Opticrom are great for reducing itchiness and soothing your eyes (ask your optician or pharmacist if they’re suitable for you).  However, make sure you don’t use these while wearing contact lenses, as the lenses may absorb the drops.
  • Try not to rub your eyes, as this will only make them worse!

Waterproof eye make up is less likely to run if your eyes are watery.

It makes a difference !

Wet those dry watery eyes!

April 5th, 2010

Did you know that watery eyes can be a symptom of dry eyes?

If your tears aren’t oily enough, they will evaporate more quickly, leaving your eyes red, gritty and dry.  When this happens, your eyes will compensate by producing extra tears. But because the tears aren’t good quality, they often run down your face, instead of remaining on your eye and doing the job they’re supposed to.

This can be more noticeable when you’re doing concentrated work like reading or driving, as your eyes become irritated when you blink less.  Also, when you’re outdoors, your eyes may also water as the wind also aggravates dry eyes.

There are numerous drops available for dry eyes.  Most of them are quite watery, and give only very temporary relief. Eye ointments will remain in your eyes for longer, but are quite greasy, so are usually only suitable for night time as they can blur your vision..

My favourite eye drops are Hylo-Tear. These have just the right consistency.  They are oily and silky, but not so viscous that they will blur your vision.  Every time you blink, they re-coat the eye, giving lasting relief.

They have a clever pump action, releasing each drop without letting germs in, so you can keep them for 3 months from opening if they’re not already empty!

They are slightly more expensive than other eye drops, but well worth it.

Don’t let astigmatism limit you!

March 29th, 2010

Do you have astigmatism?

Have you been told in the past that contact lenses aren’t an option for you?  You’ll be delighted to hear that in recent years, there have been several advances in ‘toric’ contact lenses for astigmatism.  They are now even available in disposables (use once and throw away).  This means that you can now enjoy clear vision with contact lenses despite having astigmatism.

What is astigmatism?

This word describes the shape of your eye. It means that your eye is more oval than round, (shaped more like a rugby ball than a football)..

This can be corrected in glasses by putting extra power in the lens in one direction only compared to the rest of the lens.  This will help compensate for the irregular shape of your eye.

Because it is a correction for the shape of your eye, and not just the distance you’re looking at, it improves vision at all distances, including reading, computers and further away.

Are you tired of wearing glasses full time because contacts weren’t suitable for you before?  It’s definitely worth trying again.  Everyone likes to vary their look from time to time.  Call in, and we can let you try some of the best contact lenses available for astigmatism.

Whats happening to my eyes ? I’m forty something!

February 28th, 2010

Do you sometimes feel that your arms are not long enough or that the light is too poor for reading or that print is getting smaller ? Are you now over 40 ? Your eyes are the window to your body and unfortunately like the rings which age a tree, the progressive deterioration in the ability of our lens to focus is directly related to our age.

It is a natural consequence of the aging process and impacts you even if you never had a eye sight problem before.  We often hear of people who claim that they never required reading glasses, even though they were well past 50. They often had an undiagnosed prescription for short sightedness (They could not see perfectly in the distance).

While symptoms such as fatigue while using computers or doing close work, headaches, eyestrain, inability to read small print,  can present suddenly, it generally has developed over a period of time.

The lens prescription you will require will be determined by a combination of computerised readings and Optometric skill and experience.  However you should look on this as the beginning of taking better care of yourself. Your body needs more care at is ages to ensure you can enjoy life to the fullest.  Your sight exam will include a wide range of checks for diseases which become more prevalent with age.  After all looking through they eye is the only way to look inside the body without invasive techniques such as surgery.  Care for your eyes and your health, your real wealth.

Are Green Energy Bulbs damaging your eyes ?

February 20th, 2010

It was recently brought to our attention by an eye specialist that the amount of Ultra Violet radiation emitted by many of the new green energy bulbs is equivalent to being out on a sunny day. Would you expose your eyes to that level of radiation with out UV protection on your sunglasses ?

UV light is widely regarded as one of the causes of cataracts. The invisible UV component of sunlight promotes free radical damage in the lens. The greater the light intensity the greater the UV radiation dosage and resulting damage.

The impact of radiation is cumulative over ones life and thus we see the formation of skin cancers many years after sun exposure.

Some vitamin supplements can help with the prevention of cataracts and macula degeneration, but in most cases cataracts gradually get worse and an operation is required to remove the damaged lens and the insertion of a synthetic lens.  These synthetic lenses have improved enormously over the years and one has no longer to wear the bottle bottom lens types in order to have good vision. However the operation is a somewhat uncomfortable experienced for a few weeks during the post operative healing process for many patients.

The Health Protection Agency in the UK have been one of the first to identify the problem with the new bulbs. The industry Lighting group has commissioned further independent research into the claims and have welcomed the precautionary advice issued.

More recently the Australian Government  Radiation Protection and Nuclear Safety Agency conducted test on a number of well known branded lights and found that of the brands they tested that the bulbs did not created hazardous conditions for most skin types. However they did not address the impact of build up of radiation and the impact on eyesight with regard to development of cataracts.

The most comprehensive  literature I can find on this matter suggests that more research is needed to determine if these bulbs can have negative health impacts. Green Facts.org give a reasonably balanced picture on the current status.

In conclusion – if there is danger – why not take the precaution of ensuring that if you work with a compact fluorescent lamp at your desk, make sure its got a cover and that your eyes are protected from any potential UV harm and preferably that you use an encapsulated double envelope such as that on the right of the picture below.
