Winter Eye Health

The winter weather can be particularly harsh on your eyes and presents us with new and different reasons to protect them. Winter also comes with extreme temperatures, humidity, and precipitation, so don’t let it affect your vision.

Here are some of the ways winter can affect your vision, or exacerbate an eye condition, including some winter eye health tips for prevention.

Driving in winter
It can be difficult to see when driving during the long nights of winter, and it’s easy to understand why more accidents happen at night. Your pupils are larger in the dark than in the daylight, and your depth of field decreases when your pupils are large.

With the longer nights, you are forced to drive more regularly at dusk and dawn. The glare of the lower sun creates more difficulty for drivers, so make sure your windscreen is clean, both inside and out. Have your eyes tested to ensure you have the best vision possible? It is useful to have a pair of sunglasses with good UV protection in the car to help with the glare from the sun.

Dry eyes
When it’s cold outside, we know how tempting it is to stand in front of the heater or pump up the heat of your air conditioner to warm up. However, by doing so, you may be putting your eye health at risk. Apart from drying out the surrounding air, heat causes the tear film on your eyes to evaporate, drying them out and causing discomfort.

If you already have dry eyes, central heating may exacerbate them. Running a humidifier in your home to improve the quality of your indoor air will help as well. If your best efforts don’t improve things this winter, your eye doctor may need to prescribe a remedy. The treatment for dry eyes depends upon the cause, so it is important to speak to your optometrist if your eyes feel dry, gritty, and red.

There are some simple steps you can take to minimize the discomfort caused by dry eyes in winter:

Lower the temperature in rooms when possible.

Blink more
Many people find that their dry eye gets worse when reading or using a computer. This is because we blink less when we are doing anything that needs a lot of visual attention. Use a humidifier at work and home. Opening windows for a few minutes on cold days will also help. Moisten your eyes with artificial tears.

Time spent indoors
People tend to watch more television and spend more time using computers during the winter. Remember to take breaks and operate the 20:20:20 rule; every 20 minutes, take a 20-second break and focus your eyes on something at least 20 feet away.

Winter lighting
The lower levels of light in winter can make reading and close tasks more difficult, especially for older people and those with existing vision problems. Extra light, in general, can help, and light for these sorts of activities should be as close as possible and be flexible enough to direct exactly where you need it most.

Watery eyes
In cold and windy conditions, many people complain that their eyes water more than normal. Wearing spectacles will protect against the wind, even if you don’t usually wear them outdoors. Ailments like dry eyes, redness and irritation, and even pink eye are common this time of year; it’s important to see your Optometrist should you experience persistent watery, red, scratchy, or itchy eyes.

Don’t let winter get to your eyes, visit your Optometrist at World of Vision to maintain winter eye health. Call 012 653 2288 or email centurion@worldofvision.co.za for more information or to book an appointment.

How your eyes change as you age

How your eyes change as you age

As we age, our eyes start to show an age-related decline in performance. The decline typically starts in your 40s and continues as you get older.

There are some subtle changes in your eye structure and vision that occur.

  • The muscle that controls the size of the pupil and how it reacts to light get weaker which leads to reduced pupil size. Older people, such as those in their 60s, will need more light to maintain good vision.
  • The body produces fewer tears as it gets older, which results in dry eyes. Burning, red and teary eyes are symptoms of dry eyes.

Some changes are more noticeable than those mentioned above. These changes are a little more serious and usually, require glasses or surgery to help you cope with them. Two major changes that affect everyone are presbyopia and age-related macular degeneration.

In your 40s and 50s, you will notice that it is more difficult to focus on objects that are closer to you. This is known as Presbyopia. At first, you may be able to compensate for Presbyopia, by moving the object you are trying to focus on a little further away. When this doesn’t help anymore, it’s best to visit your Optometrist, who can then establish if a simple pair of reading glasses or more advanced Varifocal lenses are needed. Presbyopia is the natural hardening of the lens of the eye. The lens loses its flexibility, making near tasks more difficult.

Age-related macular degeneration or AMD is an age-related eye disease that can affect you later in life. But it’s not just age that raises your chances of getting the disease. Genetics, health (Hypertension, Diabetes) and external factors (harmful UV rays) all play a role.

AMD affects your central vision and can be devastating if not treated early.

If you are over 40 and are worried about your eyesight, it is a good idea to make an appointment with an optometrist.

The importance of regular eye examinations for your child

The importance of regular eye examinations for your child

Vision is the most important aspect in the development of a child as it assists in both sensory and motor development. Vision is much more than just being able to see close or far objects. It is important to realize by not identifying problems early, one may affect the normal development of a child. At least 80 % of what children learn, comes through their eyes. Vision problems can adversely affect school achievement, sporting ability and social integration.

Studies have shown that 1 in 4 children of school age and 1 in 20 pre-primary children suffer from visual problems that could affect their performance.

A comprehensive eye examination may identify a visual problem that could prevent the child from achieving his/her full potential. The sooner the problem is discovered, the greater the chance of correction. EARLY DETECTION IS VITAL!

One or more of the following signs could indicate that a child has a vision problem. Book an appointment with your World of Vision Optometrist as soon as possible.

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

Above signs indicate either a refraction problem (Nearsighted, Farsighted or Astigmatism) – Spectacles will be prescribed, or a visual developmental problem, which can be treated with Visual therapy.

It is advisable to take a child for an eye examination before they take the big step of going to grade R. After the age of five, children should have their eyes examined at least once a year by a qualified optometrist.

Set aside a 1/2 hour, ensure peace of mind for yourself and help build the foundation for your child’s academic achievement in future!

Eye care tips for summer

Eye care tips for summer

Summer is here, and so is the harsh sun that can damage your eyes. Now is the time to ensure that you take good care of your eyes and protect them properly.

Below are some useful tips that can help protect your eyes this summer.

Wear Sunglasses
Wear sunglasses that offer 100% UV protection or ones that are polarised. Larger framed glasses are better as the large frame blocks out more UV rays. On cloudy days, it is recommended to wear sports sunglasses. Don’t let the clouds deceive you, UV rays are still hurting your eyes. Sunglasses get scratched easily, or you lose them without realising, so always keep a second pair of sunglasses handy.

Wear a hat or a sun visor
For extra protection, make sure you wear a hat. The wider the brim, the more your eyes are shaded from UV rays. That hat is an additional barrier between you and the sun’s rays.

Stay hydrated
Dehydration can affect your eyes. When you are dehydrated, your body can’t produce tears which lead to dry eye symptoms and other vision problems. It is extremely important to keep your skin and eyes hydrated. Drink at least 2 liters of water every day.

Avoid midday sun
If possible, stay indoors between 10:00 and 15:00. The sun’s rays are at their strongest during this time. Need to go outside? Make sure you are wearing sunglasses with 100% UV protection or polarised glasses, which help reduce the glare from the bright sun.

Wear goggles when you swim
Protect your eyes from pool chemicals. The amount of chlorine in a pool can be harmful to your eyes. Make sure you wear goggles when you go for a dip in the pool. Goggles will also help keep other bacteria entering your eyes that can cause infections. While we are discussing pools, we recommend that your remove your contact lenses before getting into the water.

Wash your hands
Wash your hands on a regular basis to protect yourself from the spread of disease. Germs come into contact with your eyes when you rub them with dirty hands; these germs can cause infections. However, if possible, avoid rubbing your eyes even with clean hands.

Eat healthy
What you eat can affect your eyesight. You need to eat foods that are rich in nutrients that improve eyesight and help prevent the development of long-term vision eye problems. Eat plenty leafy greens, carrots, citrus fruits, fish that are rich in omega 3 and nuts and seeds

Use Eye Drops
Despite your best efforts to keep your eyes healthy and moist, you might need eye drops to minimise discomfort from dry eyes. When your eyes are dry, they become more sensitive to light and vision could become blurry. Any eye that is not lubricated is more susceptible to scratches and infections.

So, if you are going to the beach this summer or lying by the pool catching the sunny rays, make sure you have your sunglasses, hat and water bottle. Look after your eyes this summer.

Teach your child healthy eye care:
UV protection for their eyes are just as important as UV protection for their skins.  Make sure they wear a hat and good sunglasses when exposed to the sun!

Encourage them to follow a balanced diet and drink enough water.

This is particularly disconcerting as 90% of all critical decisions that drivers make are based on sight.

Having good vision is essential for safe driving and even a slight compromise in your vision affects not only how well you can see objects in the distance, but will negatively affect your reaction time, depth perception, peripheral vision and night time vision.

Driving Tips

  1. If you have trouble seeing in low light, consult your Optometrist to identify any vision problems. You may be a candidate for prescription night-driving glasses, even if you don’t wear glasses during the day.
  2. Ask your eye care professional for glasses with anti-reflective coating which reduce sun or headlight glare, giving you sharper driving vision.
  3. If you suffer from dry-eye syndrome, treat it immediately. This eye condition will cause you to experience light scatter.
  4. Keep your car in sound working condition to eliminate interference with good driving vision. Clean your headlights, windows and mirrors before driving at night. Use your window defoggers in bad weather. Drive slowly and turn on your high-beam headlights in dark areas when there is no danger of interfering with other drivers’ vision.
  5. Contact lenses provide you with a natural and unobstructed view of the road along with fewer distortions to enhance your seeing and driving ability.
