Correcting presbyopia with contact lenses

Correcting presbyopia with contact lenses

Myth: Only eyeglasses can correct Presbyopia

Fact: It is well-known that progressive spectacle lenses help you to see clearly, but did you know that presbyopes now have multifocal contact lenses that allow excellent vision at all distances? 

Contact lenses are great for those who do not like the feeling of wearing eyeglasses, do not like the look of eyeglasses, or those who lead a more active lifestyle.

The NaturalVue® Multifocal 1 Day Contact Lenses are a great option to correct Presbyopia, as these lenses offer excellent vision at all distances1 – at near (reading your phone), intermediate (computer distance), and far (trees and road signs) – without using readers. 

In a clinical study1, people with presbyopia gave higher ratings to NaturalVue Multifocal for vision in everyday situations vs. their current correction. NaturalVue® Multifocal Contact Lens wearers can perform 92% of daily activities without reading glasses, even in low light.

People prefer NaturalVue™ Multifocal 1 Day contact lenses over some options for better vision1, like reading very small print or using a cell phone:

Why NaturalVue® Multifocal?

  • See clearly like spectacles2 with little compromise
  • No need for readers – Clear vision near, far, and everywhere in between
  • Superior overall vision – 89% found better vision for everyday activities.1
  • Daily disposability for a fresh new pair every day
  • Added UV protection for your busy outdoor days**

**UV absorbing contact lenses aren’t substitutes for protective UV absorbing eyewear – for example, protective UV absorbing goggles or sunglasses – because they don’t completely cover the eye and surrounding area. Patients should continue to use UV absorbing eyewear as directed. Note: Long term exposure to UV radiation is a part of risk factors associated with cataracts. Exposure is according to a number of factors, for instance, environmental conditions (altitude, geography, cloud cover) and personal factors (extent and nature of outdoor activities). UV absorbing contact lenses help provide protection against harmful UV radiation. However, clinical studies have not been done to demonstrate that wearing UV absorbing contact lenses reduces the risk of developing cataracts or other eye problems.

5 biggest myopia myths

5 biggest myopia myths

1. Myopia can be cured or reversed with eye exercises.

FALSE: While eye exercises may relieve eye fatigue temporarily, there is no scientific evidence that myopia can be reversed or its progression slowed down with eye exercises.  

2. Contact Lenses are unsafe for kids

FALSE:  Daily disposables provide decreased inflammatory adverse events (12.5x less) as compared to reusable contact lenses1

In fact, children may be safer soft contact lens wearers than teens with more  

parental supervision and support. 

3. Soft multifocal contact lenses are not effective in reducing myopia progression. 

FALSE:  The NaturalVue® Multifocal 1 Day Contact Lenses are indicated to reduce myopic progression in children.  NaturalVue Multifocal 1 Day soft contact lenses utilize patented optics to move the light rays inside the retina so that the signal for the eye to grow and elongate is reduced (addressing Peripheral Hyperopia). 2,3

NaturalVue® Multifocal 1 Day Contact LensesProven to Decrease Myopia Progression in 98% of children studied.

  • 81% of children’s progression stopped completely, with some showing reversal. 4
  • 0.82D average dioptric decrease per year in children ages 6-194*

4. Wearing glasses that correct their vision is sufficient for myopic kids

FALSE:  Data has shown that routine correction of myopia in eyeglasses or contact lenses increases myopia by signaling the eye to elongate or grow.  This occurs when routine correction moves images behind the retina (known as peripheral hyperopia) which may signal the eye to grow.5

Data suggests that the optimal correction should bring the image inside of the retina.5 The patented optics of NaturalVue® Multifocal contact lenses focus peripheral light rays in front of the retina to remove peripheral hyperopia, thus reducing the signal for the eye to grow.2,3

5. It is better to be undercorrected so that our myopia will not worsen.

FALSE:  Undercorrection of myopia may lead to the stimulation of eye elongation due to the presence of blurred vision at any distance and accelerate the progression of myopia. Instead, a full distance correction for myopia with a progressive reading addition is suggested to reduce the progression of myopia.6

Myopia – Risks and Management

Myopia – Risks and Management

What is myopia?

Myopia is a very common eye health condition. Often called “short-sighted,” a child with myopia can see clearly up close but has blurry vision when looking at objects in the distance—like a smartboard.

Myopia happens when the normal eye grows too long from front to back. 

Light rays have trouble reaching the right spot on the back of the eye (the retina) to achieve clear distance vision.

It’s more than just stronger, thicker glasses. Myopia in kids can get worse as they grow, increasing the risk of serious eye conditions.

What causes myopia?

  • Myopia can be inherited from one generation to the next. If mum or dad wears glasses, chances are their child will too.1
  • Lack of time spent outdoors in the sun has been linked to the development of myopia.1, 2,3
  • Spending more time reading close-up on digital devices may also contribute to a child’s myopia.2,3,4
  • And there’s the routine correction of myopia – resulting in Peripheral Hyperopia – that has also been shown to signal the eye to grow, thus causing myopia.2

What are the eye health risks?

The number of kids with myopia is growing at an alarming rate around the world.  The younger your child develops myopia, the greater the risk of serious eye conditions like retinal detachment, glaucoma, cataracts, and even blindness.5

Beyond the eye health risks, myopia can negatively impact your child’s performance in school and other activities.

There is NO SAFE level of myopia.5  Practitioners and researchers do not know which child will progress to what degree.  Each prescription (diopter) increase can have a significant impact and the impact can occur anywhere – in low to high myopia ranges.6   Earlier intervention may be ideal, but any intervention is a potential benefit.   If we can reduce the level of progression, data suggests that the impact could be significant:

  • 20% reduction in retinal detachment, cataracts, glaucoma, and overall visual impairment.6
  • 40% reduction in macular degeneration. 6

This means – ½ to nearly 1 year of visual impairment could be saved. 6

What are some evidence-based ways to slow down myopia progression?

Your eye care practitioners may be able to help slow or control your child’s myopia with specially designed glasses, eye drops, or contact lenses. All of these solutions have been shown to have various levels of effectiveness.  Talk to your eye care practitioner for more information like how each works, effectiveness rates, benefits, and limitations. 

  • Specially Designed Eyeglasses
  • Pharmaceutical Eye Drops (Atropine)
  • Specialty Contact Lenses
    • Hard contact lenses (or Orthokeratology or Ortho-K lenses) that physically re-shape the cornea at night during sleep.
    • Soft multifocal contact lenses like NaturalVue® Multifocal 1 Day Contact Lenses. 
      • NaturalVue Multifocal 1 Day soft contact lenses, by comparison, utilize patented optics to move the light rays inside the retina so that the signal for the eye to grow and elongate is reduced (addressing Peripheral Hyperopia). 16,17
      • These lenses provide excellent vision by day.18
      • These lenses are daily disposables, which means comfortable daily wear with no cleaning or maintenance.
      • Clinically effective for myopia progression control.19  
        • 98% of children showed a decrease in myopia progression19
        • 81% of children’s progression stopped completely, with some showing reversal. 19
        • 0.82D average dioptric decrease per year in children ages 6-1919*
