Short Arm Disease…. Most of you’ll get it after 45 years old

“Short Arm Disease”,

One of the best joke to tell someone that you are getting older and have a condition called Presbyopia. It explains as when you reach 40s and above, you will start to push your reading material slightly further away for ability to see clearer….. until a certain point where your arms not “Long Enough” and you need reading glasses to help.

Presbyopia isn’t a horrible thing. Its just something that happens to most of us when we gets older and suddenly all Near  Reading activities becomes difficult or blurry.

If you want a proper explaination try this:

“Presbyopia is a condition where the eye exhibits a progressively diminished ability to focus on near objects with age. Presbyopia’s exact mechanisms are not known with certainty; the research evidence most strongly supports a loss of elasticity of the crystalline lens, although changes in the lens’s curvature from continual growth and loss of power of the ciliary muscles (the muscles that bend and straighten the lens) have also been postulated as its cause. Like gray hair and wrinkles, presbyopia is a symptom caused by the natural course of aging.

The first signs of presbyopia – eyestrain, difficulty seeing in dim light, problems focusing on small objects and/or fine print – are usually first noticed between the ages of 40 and 50. The ability to focus on near objects declines throughout life, from an accomodation of about 20 dioptres (ability to focus at 50 mm away) in a child, to 10 dioptres at age 25 (100 mm), and levels off at 0.5 to 1 dioptre at age 60 (ability to focus down to 1–2 meters only). The expected maximum and minimum amplitudes of accommodation for a corrected patient of a given age can be determined using Hofstetter’s formulas: Expected amplitude (D) = 18.5 – 0.3 x (age in years), Maximum amplitude (D) = 25 – 0.4 x (age in years), Minimum amplitude (D) = 15 – 0.25 x (age in years).”

Simple explaination is that you need reading glasses for all your near activities when you reach those stages.

Yes, it means when you are texting on your iPhone, playing with your iPad, reading Newspaper, Browsing the internet on your laptop, reading small medical label prints, flipping through Magazines, doing accounts, choosing the red beans out from the green ones….. yes… all those near activities that is range arms length away will be difficult when you have Presbyopia.

Luckily the solutions are simply. Have your near sight Corrected. There are a few solutions for it, such as:

  • Reading Glasses.
  • Progressive Lenses.
  • Monofocal Contact Lenses.
  • Multifocal Contact Lenses.
  • Laser surgery.

All of the above suits different persons accordingly. Therefore, in order to get the best out of it, go for a proper full eye examinations and consult your local Optometrist for the best solutions.

What is Progressive Lenses?

Progressive spectacle lenses, also called progressive addition lenses (PAL), Progressive power lenses, Graduated Prescription lenses, and Varifocal or Multifocal lenses, are corrective lenses used in spectacles to correct presbyopia and other disorders of accommodation.

They are characterised by a gradient of increasing lens power, added to the wearer’s correction for the other refractive errors.

The gradient starts at the wearer’s distance prescription, at the top of the lens and reaches a maximum addition power, or the full reading addition, at the bottom of the lens.

The length of the progressive power gradient on the lens surface depends on the refractive index of the lens, with a final addition power between 0.75 to 3.50 dioptres for most wearers. The addition value prescribed depends on the level of presbyopia of the patient and is closely related to age and to a lesser extent, existing prescription.

Advantages of Progressive Lenses

There are various advantages of Progressive lens to wearers. We can summarize the primary benefits of progressive lenses as follows:

  • No bifocal lines. The most obvious advantage to progressive lenses is the absence of any visible lines of demarcation, which are considered tell-tale signs of age.
  • Intermediate utility. Progressive lenses produce a gradual change in power from the distance zone to the near zone, which affords the wearer an infinite range of focus between distance and near. This infinite range of focus provides excellent intermediate or mid-range utility, which becomes absent from traditional bifocal lenses as the Add power increases.
  • No image jump. Traditional bifocal lenses produce a jump in magnification and image location when crossing the segment boundary, as well as blur and scotoma—or blind area—around the segment margin. The gradual change in power of progressive lenses results in a lens design that is free from any abrupt changes in vision.

 

Choosing the Best Progressive Lenses for Your Needs

For all powers of progressive lenses to fit within a pair of spectacles, frames in the past had to be relatively large. If the frame was too small, the reading portion of the lens would sometimes end up uncomfortably small after the lens was cut to size and inserted in the frame.

But lens manufacturers have overcome this problem by introducing “short corridor” progressive lenses with compact designs that provide larger reading zones for today’s smaller, fashionable frames.

The popularity of progressive lenses has exploded in recent years, making progressives the most widely purchased lenses for correcting presbyopia. Today there are many progressive lens designs to fit virtually any needs.

The differences in lens design are related mainly to the length and width of the progressive power corridor and how much of it is devoted to different viewing distances. Different areas of the corridor may be expanded, depending on the design philosophy of the manufacturer and the intended purpose of the lens.

Some progressive lenses are made specially for computer use, for example, and have a wider intermediate zone. Other progressive lens designs may have a larger reading portion. Your eye care practitioner is in the best position to evaluate which lens style will work best for you.

Progressive lenses also are available in a wide variety of materials, including regular plastic and glass, polycarbonate, high-index and photochromic lenses.

Ho Optometrist provides a large range of Progressive lenses that caters for all needs. For more information please contact us.

CAUTION! Eye Drops to Remove Red Eyes.

When you wake up this morning your eyes suddenly turns Pink, what will you do?

Most people will say go consult the Eye Doctor, some says just go to the pharmacy to get some eyedrops; WORST case is tho find for leftover eyedrops in their own fridge.

Most people are unaware that most eyedrops only last a month once open, no matter where you store it. It is dangerous to simply put any eyedrops that ” YOU THINK IS SUITABLE” into your eyes that might be infected.

As for those who just visits the pharmacy to get OTC eyedrops available to help reduce the redness of your eyes. These types of eyedrops are known as VASOCONSTRICTORS. But are you aware of the potential side effects from overuse of these drops?

Vasoconstictors can be explained as eyedrops that constricts you blood vessels causing a ” Bleaching Effect”, leaving your eyes looking healthy and white. However, this drops also hides the true nature of your eye condition when Conjuntivitis is the case, leading to misdiagnosis.

If one continues using these eyedrops frequently, there is actually a “rebound redness” that can occur as your eyes become accustomed to the drop.  Your eyes will actually become redder with continued use.

In conclusion, the main point from this post is that:

” If your Eyes are RED, do not simply put Eyedrops.”

  Go see Eye Doctor before you MAKE THINGS WORSE.

Can I Use Eye Drops With My Contact Lenses?

Yes. There are certain eye drops that can be used with contact lenses.

Most over-the-counter eye drops are divided into three categories: “Dry Eye” eye drops, “Get The Red Out ” eye drops and “Contact Lens” eye drops.

“Dry eye” eye drops:

Dry eye drops come in a variety of formulations. Some are thicker than others and may actually cloud your vision or “gum up” your contact lenses. While some of them may be okay for use with contact lenses, they are designed to not only lubricate the eye, but to promote healing of the eye’s surface.

Systane® Lubricating Eye Drops from Alcon® Laboratories, are for sufferers of dry-feeling eyes.

Dry-feeling eyes is an increasingly common 21st century problem due to changes in the way we live, such as the increased use of computer screens, central heating and air conditioning.

Systane® offers unique protection for immediate comfort and long lasting relief from dry-feeling eyes – particularly morning and end of day dryness. The highly developed formulation gets to work as soon as the eye drop comes into contact with your eyes. It contains a unique polymer system which means that upon contact with your tears, the liquid eye drop turns into a thin protective gel layer. The gel-like barrier stays on the ocular surface longer than some conventional drops providing fast and long lasting relief.

Tears Naturale Free® is preservative-free. 

 If your Eye Doctor or Opthalmologist or Optometrist has recommended a preservative-free product for you dry eye condition, then Tears Naturale Free® would be an excellent choice.

 

“Get the red out” eye drops:

“Get the red out” drops have special ingredients called VASOCONSTRICTORS. These drops shrink the tiny blood vessels in the conjunctiva, the clear tissue that coats the white part of your eye. These eye drops could cause deposits to form of the surface of your contact lenses and if used repetitively to re-wet your contact lenses, could cause “rebound” redness. Rebound redness occurs when the vasoconstrictor wears off. The blood vessels dilate larger, causing the eyes to appear bloodshot. This may cause dependency or mask underlying infections or inflammations.

“Contact lens” eye drops:

Contact lens eye drops are often called re-wetting drops. Re-wetting drops lubricate your eye and hydrate the contact lens, making your eyes more comfortable while wearing your contact lenses. Theses eye drops are labeled “For use with soft contact lenses,” and are usually located next to contact lens cleaning solutions in the store. Eye care professionals usually encourage frequent use of re-wetting drops, as it improves comfort and helps clear out debris underneath your contact lenses.

Renu MultiPlus Lubricating & Rewetting Drops are the simple way to condition your lenses.

 Moisturise your soft contact lenses while wearing them with Renu MultiPlus Lubricating & Rewetting Drops. Renu MultiPlus Lubricating & Rewetting Drops contain Povidone, an effective lubricant that provides moisturising comfort for optimal lens wear.

 

COMPLETE Blink-N-Clean® Lens Drops is another eye drop product indicated for use to lubricate and rewet soft contact lenses, including disposable, daily wear, and extended wear lenses, and RGP contact lenses.

Talk to your eye doctor if you are taking any eye drops for medical eye problems, such as glaucoma. Ask your eye doctor for the best way to insert eye drops and whether or not contact lenses should be worn while taking your medication.

What are the Main Causes of Blindness?

According to World Health Organization there are 285 million people are visually impaired worldwide, among them 39 million are blind and 246 have low vision.

About 90% of the world’s visually impaired live in developing countries.

‘ Globally, uncorrected refractive errors are the main cause of visual impairment; cataracts remain the leading cause of blindness in middle- and low-income countries. ‘

The number of people visually impaired from infectious diseases has greatly reduced in the last 20 years. 80% of all visual impairment can be avoided or cured.


Definitions

There are four levels of visual function, according to the International Classification of Diseases -10 (Update and Revision 2006):

  • Normal Vision
  • Moderate Visual Impairment
  • Severe Visual Impairment
  • Blindness.

Moderate visual impairment combined with severe visual impairment are grouped under the term “low vision”: low vision taken together with blindness represents all visual impairment.

The causes of visual impairment

Globally the major causes of visual impairment are:

  • Uncorrected refractive errors (myopia, hyperopia or astigmatism), 43 %

  • Cataract, 33%

  • Glaucoma, 2%.

 Who is at risk?

Approximately 90% of visually impaired people live in developing countries.

People aged 50 and over

About 65 % of all people who are visually impaired are aged 50 and older, while this age group comprises about 20 % of the world’s population. With an increasing elderly population in many countries, more people will be at risk of age-related visual impairment.

Children below age 15

An estimated 19 million children are visually impaired. Of these, 12 million children are visually impaired due to refractive errors, a condition that could be easily diagnosed and corrected. 1.4 million are irreversibly blind for the rest of their lives.

Changes over the last twenty years

Overall, visual impairment worldwide has decreased since the early 1990s. This is despite an aging global elderly population. This decrease is principally the result of a reduction in visual impairment from infectious diseases through concerted public health action.

The global response to prevention of blindness

Globally, 80% of all visual impairment can be prevented or cured. Areas of progress over the last 20 years include:

  • governments establishing national programmes to prevent and control visual impairment;
  • eye care services increasingly integrated into primary and secondary health care systems, with a focus on the provision of services that are available, affordable and high quality;
  • campaigns to raise awareness, including school-based education; and
  • stronger international partnerships, with engagement of the private sector and civil society.

Data over the last 20 years shows that there has been significant progress in preventing and curing visual impairment in many countries. Furthermore, there has been a massive reduction in onchocerciasis-related blindness as part of a significant reduction in the disease. This has been achieved through a number of successful international partnerships.

Spectacles Donation for the Children.

FACES, a Local Ipoh Charity Organization collaborated with Ho Optometrist an eye testing event for children from Praise Emmanuel Home and Good Shepard Home.

On that Sunday, a total of 28 children drop by for this event. The children age ranges from 3 till 18 years. All fo them had their full eye examination at Ho Optometrist, Jalan Sultan Idris Shah.

 

 

The Resident Optometrist of Ho Optometrist, Mr. Deric Ho did refraction and eye assesments for all the children. It is important having eye screening for young children as any visual impairment should be detected early. In majority cases, most of the children are unable to inform their parents or teachers that their vision is blur or unable to see clear.

” It is common for children with Visual Difficulties showing symptoms such as Abnormal Head Tilt, Eyes Squinting, Rubbing their eyes, or copying wrongly from school.”

 

This is an issue that most parents might still neglect the importance of good 6/6 vision for their child. 

Free spectacles are given by Ho Optometrist for those children who needs it to see a better future.

 

All the children had a great time with cakes and drinks.  Deric is glad that Ho Optometrist had this opportunity to co-organize with FACES for such a meaningful event fulfilling the needs of these children.  

 

Most importantly, the children are now capable of reading and learning with a Clearer picture.

 Don’t expect to get another when bad things happen!

 

As we read through newspapers and  online news many countries around the world faces numerous cases of contact lens complications leading them BLINDNESS….. which IT COULD BE PREVENTED…

Nost of them Do Not Clean their Contact Lenses Properly……. Overwearing the Lenses…… No Hygiene At ALL…….. and Not Having Any Idea of Wearing Contact Lens….

Some people buy Contact Lens Online thinking that it is just like buying another pair of beauty accessories…. like earings…… You Just Stuck It In!!! Its That Easy….
