Easy Ways to Care for Your Eyes this Spring

Invest in a good pair of sunglasses: Proper UV protection is crucial for your eye’s health. In addition to blocking out harmful UV rays the correct sunglass lenses can enhance your vision in many ways. Polarized lenses eliminate glare. Light enters the lenses only from a certain direction/angle, blocking light reflecting off surfaces around you. This means no more glare from the tar surface of the road, the car approaching you or water surfaces.

Enhancing your driving and outdoor adventures
Different coloured lenses absorbs different spectrums of visible light and each has their own unique properties and advantages.

At World of Vision our Optometrists and Dispensing staff have the knowledge to guide you to select a pair of sunglasses that not only suit your looks but also your unique lifestyle.

Eye allergies: Spring not only brings warmer weather but dreaded allergies too!
Eye allergies are characterized by red, itchy, watery eyes that are caused by the same irritants that cause sneezing and a runny nose among seasonal allergy sufferers. If you think you have eye allergies, here are a few things you should know – including helpful tips on how to get relief from your red, itchy, watery eyes.

What causes eye allergies
Allergens are normally harmless substances that cause problems for individuals who are predisposed to allergic reactions. The most common airborne allergens that cause eye allergies are pollen, mold, dust and pet dander. Eye allergies also can be caused by reactions to certain cosmetics or eye drops, including artificial tears used for treating dry eyes that contain preservatives. Food allergies and allergic reactions to bee stings or other insect bites typically do not affect the eyes as severely as airborne allergens do.

Eye allergy relief – To get relief from your eye allergies and itchy, watery eyes, you can take a few approaches:

Avoid allergens
The best approach to controlling your eye allergy symptoms is to do everything you can to limit your exposure to common allergens that you know you are sensitive to. If staying indoors all the time is not an option, wear wraparound sunglasses to help shield your eyes from pollen, ragweed, etc., and drive with your windows closed.

Remove your contacts
Because the surface of contact lenses can attract and accumulate airborne allergens, consider wearing glasses instead of contacts during allergy season. Or consider switching to daily disposable contacts that you discard after a single use preservatives.

When you do go outdoors during allergy season, wear wraparound sunglasses to help shield your eyes.

Your Optometrist at World of Vision can quickly identify eye allergies and recommend the best eye drops and treatment plan to follow.

Enjoy Spring!

Spending more time on digital devices during Level 3 Lockdown?

Spending more time on digital devices during Level 3 Lockdown?

Blue light is everywhere – During the Covid -19 worldwide pandemic, our digital world has expanded more than ever.

From work to school to spare time, we are all using some sort of digital device for long hours every day and we are bombarded by blue-light from these man-made sources. Research suggests that this cumulative and constant exposure to blue light can damage our eyes, specifically the retina cells. There is expected to be an increase in the number of patients at risk for macular degeneration in the coming decades.


1. Eye Strain
Because your eyes are working extra hard to cope with the blue light, you begin to experience eye strain. Over sustained periods, the exposure can contribute to long-term vision issues such as cataracts and age-related macular degeneration (AMD).

2. Headaches/ Migraines
Headache is a common symptom that is caused from too much stress on the eyes. Blue light emissions from digital screens increases the stress on your eyes. If you already suffer from light sensitivity, exposure to blue light can trigger migraines.

3. Blurry Vision
Whether it is a school paper, work spreadsheet or detailed graphic design project you are working on, it is easy to lose track of time as you are focused to get the work done. However, not giving your eyes a proper break from screen time can lead to blurry vision as our natural eye’s filters are not fit for blocking blue light.

4. Dry Eyes
Another common symptom associated with prolong exposure to blue light screens is dry eyes. With prolonged concentration on a screen we tend to blink less frequently, causing scratchy, red teary eyes.

5. Inability to Focus
Due to eye strain, chronic headaches, dry eyes and sustained concentration it makes it more difficult to stay focused while working on your computer or phone for long periods of time. You have deadlines to meet, and we get that, but it’s also important to keep your body in check in order to stay focused.

6. Disrupts Sleep Pattern
A common habit before bed is checking emails or catching up on social media. However, at night, blue light disrupts our circadian rhythm, the natural release of hormones (melatonin). The blue light tricks our brain into believing that it is daytime, which makes falling asleep more difficult and lowers our sleep quality. Circadian disruption produces serious downstream effects including increase in obesity and depression.

How do I protect my eyes?
– Have your eyes tested to detect any form of eyestrain.
– Use spectacles with specialised blue control anti-reflective properties. At World of Vision Optometrists, you can have Crizal Prevencia anti-reflective coating on your new prescribed spectacles or plano over the counter ready-made blue control glasses.
– Use lubricant eye drops to keep your eyes moist, your Optometrist at World of Vision will advise you on which eyedrops are most suitable to you.
– Take frequent breaks from your screen, even if it’s only looking away from your screen at a distant object (2m or further)for a couple of seconds. This gives your accommodation system a chance to relax and break the pattern of over focusing pattern.
– Refrain from using your digital device at least 2 hours before bedtime.

World of Vision Optometrist belongs to Essilor’s select Expert group of Optometrists, allowing us access to their technologically advanced products, including Crizal Prevencia lenses.

Seven everyday things that put your vision at risk Essilor SA

Seven everyday things that put your vision at risk Essilor SA

Most people engage in several everyday activities that unfortunately put their vision at risk.

You check your phones on a daily, oftentimes also nightly, basis, whether it is for work or play (most likely, both). Much of the time, we are doing so without protecting ourselves from excess exposure to blue light.

A hike in the woods and a day at the beach are great ways to spend time outdoors but pack your sunglasses. Not protecting your eyes now can lead to vision issues as you grow older.

Several other common actions and behaviours can cause serious eye conditions, including cancer and blindness.


Are you guilty of any of these seven everyday actions that can put your vision at risk?


Screen time has significantly increased around the world. In fact, a new study finds that the worldwide average of daily screen time is 6 hours and 42 minutes per person, with people in some countries spending as many as 10 hours a day online.

The Philippines spends the most hours daily (about 10) on screens. Brazil, Thailand and Colombia all fall in the top five, at 9 or more hours a day.

The country in which residents spend the least amount of screen time? That’s Japan, where residents are on their devices for the least amount of time per day: 3 hours and 45 minutes.

How does all this screen time affect your vision? More time spent staring at devices raises the likelihood and severity of digital eye strain.

Symptoms of digital eye strain include dry or irritated eyes, blurred vision, neck and shoulder pain, headaches and difficulty falling asleep.

What can you do to cut your screen time? Limit your time looking at smartphones, e-readers and tablets. To fall asleep more easily, avoid screens before bedtime.

Another way to deal with all that screen time. Blue light glasses — special lenses block blue light that can interrupt your sleep cycle and may contribute to your digital eye strain.


Can you count the number of times you’ve rubbed your eyes today? Rubbing your eyes can lead to serious issues like scratched corneas and cause existing vision problems to worsen.

Rubbing your eyes also can transfer bacteria and germs you picked up when you touched a doorknob or borrowed a friend’s phone. One example of the danger of rubbing your eyes: Transferring bacteria from your hands to your eyes can lead to conjunctivitis (pink eye).

When you feel as if something (eyelashes or dust, for example) may be stuck in your eye, don’t rub your eyes. Rinsing your eyes with saline or water is a safer way to remove the debris.


Caring for contact lenses properly is crucial for the health of your eyes, but some common abuses include sleeping in contacts, cleaning them incorrectly and wearing them in the shower or pool — all of which can lead to eye irritation or infection.

For example, sleeping or napping in your contact lenses can result in inflammation, blurry vision, light sensitivity and dry eye syndrome. Experts recommend taking out contacts regularly to give your eyes a break — even lenses that are approved for overnight use.

Study after study has found that contact lens wearers are not following the directions for care of their lenses. A 2015 study of adult contact lens wearers in Saudi Arabia found that 27.1% exhibited no hand washing or poor hand washing hygiene for handling their contacts, 35.7% of contact lens container hygiene was considered bad — and 1.6% of container hygiene was missing entirely.

In addition, one in five of these study participants changed their contact lenses irregularly, and as many as two thirds reported that they experienced side effects and complications from contact lens use that required medical attention.

It is important to know the risks of misusing contact lenses and to heed the advice and directions from your eye care professionals and contact lens makers.


When you are spending time in the sun, protecting your eyes from ultraviolet (UV) radiation is crucial. Sunglasses are the best form of protection and comfort against bright sunlight.

Spending a day in the sun without shades, even short-term exposure, can lead to conditions such as photokeratitis, or “sunburn of the eye.” While photokeratitis is temporary, it is painful.

Damage from UV radiation also can lead to more long-term conditions, such as cataracts, and even to cancer of the eye (although rare), the eyelids or the skin around the eye.

When choosing a pair of sunglasses, it’s important to select a pair that offers the most protection from UV radiation — 99% to 100% UV protection to be exact. Look for this level of UV protection on both prescription and non-prescription sunglasses.


Getting relief from itchy, dry, watery or red eyes can be as simple as using eye drops. However, using them excessively or improperly can potentially cause more problems for your eyes.

Overusing eye drops can lead to a dependency on them — and to clogged glands, which can be uncomfortable. Lubricating eye drops can wash away natural tears if they are used too often.

Whitening eye drops, which are used to treat redness, can cause blood flow to decrease. This can prevent essential nutrients and oxygen from reaching your eyes. As blood vessels struggle to deliver oxygen, they can grow larger and cause your eyes to appear even more red.

Allergy eye drops can be great for quick relief but should not be relied on as a permanent fix. Identifying the primary cause of an allergic response is more beneficial to both your eyes and your overall health in the long run.

If using eye drops causes your eye conditions to worsen, stop using the drops and consult an eye doctor, who can recommend or prescribe the best products for you.


One of the biggest threats to your vision health is smoking, especially if it is a daily activity. Smoking causes significant lung damage, but it can also be a factor in eye conditions that lead to vision loss and blindness.

Some of the greatest vision risks for tobacco users are cataracts and macular degeneration.

Most cataracts develop slowly, causing vision to become blurry. Cataracts also grow worse over time and eventually can lead to loss of vision if they are not treated surgically.

Your central vision, which helps you recognize faces, can be impacted by macular degeneration. Central vision is vital for tasks such as driving and reading, as well as for seeing people and objects clearly.

Some new evidence also suggests that smoking can lead to glaucoma, a condition that increases pressure in the eye and can cause serious damage to eyesight.

Smoking can cause many health and vision problems, but you can protect yourself from these conditions in one step: by stopping your smoking habits immediately.


Regular eye exams are not a daily activity but rather an everyday decision that affects both the health of your vision and, potentially, your overall health.

Vision changes as you age can be affected by other health conditions. Eye exams are important because they can reveal indications of eye conditions that have not begun to show symptoms and can address bigger issues that are connected to eye health.

Professionals recommend getting your eyes checked at least every few years (more often as you get older or are at risk for developing eye conditions) to maintain the safety and health of your eyes, and to help prevent long-term issues such as vision loss.


Contact World of Vision Optometrists and schedule a comprehensive eye exam.



10 signs you might need an eye exam

10 signs you might need an eye exam

Roughly 60% of the world’s population requires vision correction, according to the Vision Impact Institute.1 That’s a lot of people, but the good news is 80% of all visual impairment can be avoided or corrected.2

As everything in our body, our vision changes over time.  Usually gradually, which make it more difficult to notice. We need to maintain our eyes so that they function optimally. The best way to maintain your eyes is to schedule a yearly eye exam with your World of Vision optometrist. One of the clearest signs that you might need glasses is the inability to read an actual sign. But there are many other clues that can reveal if your powers of observation are fading.

  • Frequent headaches: When the small muscles in the eye are forced to work harder, you will find yourself squinting or your eyes straining. This causes headaches and is a major sign that you may need glasses.
  • Blurred vision: If your favourite book has become too fuzzy to read up close, you may be developing farsightedness or presbyopia. Difficulty reading street names while driving could indicate near-nearsightedness, while astigmatism causes confusion between similar numbers and letters at both distance and close-up.
  • Eye rubbing: If you are rubbing your eyes, you may have eye fatigue or an eye infection. Continuous rubbing can cause damage to your eye’s structures. To prevent this, have your eyes examined as soon as possible.
  • Seeing double: Double vision can lead to serious issues. If you have double vision, then there may be a problem with your cornea or the eye muscles. You need to see the optometrist if you experience these symptoms.
  • It is difficult to see at night: If you are no longer able to see the dog in the yard at night, you may be experiencing signs of cataracts, which need to be examined as soon as possible.
  • Eye strain or eye fatigue: Eye strain can be affected by various factors such as flu, allergies or not getting enough sleep. However, if you are experiencing pain and this pain lasts more than a few days, you need to get your eyes checked. If your eyes also to seem to get tired when watching TV or reading your book, it is time to make an appointment with your optometrist.
  • Reading or computer work has become difficult: If you are finding it difficult to work on the computer or read your book, you may be experiencing signs of farsightedness.
  • Squinting often: If you are often squinting, it might be because you are trying to reduce the light entering the eye and to reduce the size of the blurry image. This is often a sign of poor vision.
  • You have difficulty with light adjustments: Does it take your eyes longer to adjust to seeing a bright light or after being in the dark for a while? It could mean that the muscles that help your iris contract and expand are weakening
  • Seeing halos around lights: Seeing halos or circles around lights may be a sign that you are developing cataracts or a night vision problem. If the light is scattered or blurred, it is a sign that your eyes are struggling to focus properly.

While these signs don’t necessarily mean you have poor vision, they do indicate and eye complication – visit your World of Vision optometrist as soon as possible.

Focus on your child’s future – Their visual ability is crucial for school, sport and play

Focus on your child’s future – Their visual ability is crucial for school, sport and play

At World of Vision Optometrists, we strive to achieve the best developmental platform for all children, both on the sports field and in the classroom.  We do our best to ensure that we provide children with all the tools to assist them to perform at their best.  World of Vision Optometrists offers comprehensive visual assessments, corrective and preventative vision solutions.

At least 80 % of what children learn, comes through their eyes.  Vision problems can adversely affect school achievement, sporting ability and social integration.

Today’s children make full use of digital devices, be it for education or leisure. They spend more time doing “near work” such as texting, playing games and watching videos or movies on cell phones.  Prolonged near work can increase visual strain and incidence of nearsightedness. With the added emittance of blue light from screens, their visual systems are exposed to a far greater demand than in the past.

The following signs may be an indication of underlying visual problems:

Near vision:

      • Holds the book too close or too far from eyes
      • Frequently changes the distance at which book is held
      • Blinks frequently
      • Frequently loses place on page
      • Confuses words, syllables or letters
      • Tilts head to one side
      • Stops reading after a short period of time
      • Use finger as marker when reading
      • Lack of comprehension
      • Headaches and eye pain
      • Poor concentration

Distance Vision:

      • Squint eyes and screw up face to see clearly
      • Bends head forward while looking up at the object
      • Use head movements to follow an object
      • Seems to lose concentration when things are explained on board
      • Closing or covering of one eye
      • Sensitivity to light
      • Sitting too close to the TV

Set aside a half an hour, ensure peace of mind for yourself and help build the foundation for your child’s academic achievement in future!

Don’t wait! Play an active role in assessing your child’s vision.

World of Vision has implemented a safety-first protocol in our practice, to minimize the risk of cross-infection between staff and patients.

Our protocol is based on 3 pillars:
– Social distancing
– Protection
– Disinfection

Social distancing
We always knew having a practice of more than 500m² has its benefits to patients, for instance being able to stock more than 3000  frames at any given moment, having a manufacturing Optical laboratory on our premises and more than 1 exam room available. During the COVID-19 pandemic we can offer enough social distancing between staff and patients in our 564m² practice to ensure a safe environment. Although we have all this space, we will strictly enforce level 4 rules and regulations, e.g. Only allow 50%  of our staff to work at a time and allowing the correct amount of public into the practice at any given time.

World of Vision Optometrists will do our utmost best to prevent disease transmission through direct contact or aerosol spreading with the following protocol:

– All our staff are supplied with Personal Protective Equipment, e.g. gloves, face masks, protective shields and perspex screens.
– All members of the public/patients entering the practice must wear a two layer mask.
– Optometrists rooms have equipment screens where patient and Optometrist interaction breaches 2 metres of contact.

– All our instruments are disinfected before and after each patient. Only disinfectant containing 70% alcohol, which is recommended by the Centre for Disease Control and Prevention (CDC) are used.
– Workstations, surfaces, waiting area and lab is constantly disinfected.
– Apart from the 3-pillar protocol we also offer you front door parking.  Meaning you don’t have to enter busy public areas to access our practice. We’re just  a few steps from your parked car.

Call us on 012 653 2288 or email for all your questions, requests, or information.

Stay safe, take care
