Wearing contact  lenses even daily disposable wear lenses means eye care becomes more important.Studies have shown that  wearers who do not follow recommended replacement schedules have more complications and self-reported discomfort than contact lens wearers who follow the replacement recommendations and after care visits. The risk of inflammation and infection increases with the frequency of overnight wear,especially in non peroxide disinfecting regimes.
An eye care professional often encounters eye health issues from unsuitable contact lens solutions or regimes being employed.

Lens specifications can vary widely including water content and contact lens intolerance can include giant papillary conjunctivitis (GPC).
Latest materials consist of a silicone layer in between thin layers of soft hydrated polymers allowing for greater oxygen transmission and greater wearing time,especially important for extended wear contacts.​


Thousands of brands exist eg Daily,Bi-Weekly and Monthly products 
Suitable lenses that are approved by the U.S. Food and Drug Administration to wear during the day and to sleep in are often called “extended wear,” “continuous wear,” or “overnight wear”
However this non removal prior to sleeping  increases  the risk of getting a serious type of corneal infection called microbial keratitis especially if the wrong gas permeable material is used on a susceptible eye. The eyes are examined whilst wearing contactsdrop in shooting pr for pgd assessment and also when you remove your lenses.
Regardless of the type of  worn, rubbing and rinsing the lenses is vital in maintaining contact lens and eye health preceded by washing and drying of hands notably the middle and index fingers.

Daily disposable lenses reduced the risk of infection by 12^ times compared to reusable soft lenses: Saline is incapable of disinfecting lenses because it contains no disinfection agent.
Some people report they have been doing this without problems but in the same way some people have smoked 20 cigarettes a day and live to be 100, but that doesn’t mean smoking is safe.

  • Offer a full field of view eg freedom from glasses,sports use without fogging. 
  • There is a lens to suit almost everybody, young and old,even multifocal contact lenses
  • Ideal for sports with wider peripheral vision.
  • Affordable and convenient. 
  • ​Certain brands and designs can be worn for up to 29 consecutive nights,depending upon your  suitabilty. There are also many customised lenses available if you have particular needs or an unusual prescription.
  • Irregular cornea reshaping is possible.

​BIOFINITY lenses may be prescribed for daily wear and extended wear for up to 6 nights/ 7 days of continuous day and night wear USFDA but it is subject to patient suitability.
Not all patients can achieve the maximum wear time. It is recommended that the contact lens wearer be evaluated on a daily wear schedule. If successful, then a gradual introduction of extended wear can be followed as determined by your personal responses and your eye doctor.

Once removed, it is recommended that the lens remain out of the eye for a period of rest overnight or longer and discarded in accordance with the prescribed wearing schedule. We can advise the appropriate wearing time for your specific circumstances.  

Major brand lenses

​All lenses have their purpose and different modality.    Dailies are supplied than monthlies.
​A fresh pair of daily contacts  for daily wear are known as daily disposable contacts. Monthly disposable contacts are discarded after 30 days of wear and require more contact lens care eg surfactant cleaning with your index finger. ​
 Recent studies demonstrated that daily disposable lenses decrease the risk of CIEs (corneal infiltrative events ) more than 12‐fold compared to reusable lenses or extended wear (EW) types.
The  risk of developing a CIE may be  higher with silicone hydrogel materials as they  may bind more micro‐organisms than hydrogel lenses, but the events that occur are less severe
CLARE (contact lens induced acute red eye) has been reported with EW RGP lenses, silicone elastomer lenses, and with the over wear of daily soft lenses, a history of extended wear with hydrogel lenses is most typical, as is a uniocular presentation.  
EW research studies report yearly incidence rate between 4% to 30 % depending on lens type, lens care regimen, and lens replacement frequency.

The corneal health and regularity needs to be determined in assessing the optical correction possible.

Keratoconus - Cone shaped cornea- contact lens fitting.


Keratoconus  lens wearers be they be in Bega ,Tathra, Tura, Bombala, Narooma, Merimbula or Eden need to ensure their lens fitting and tolerance is safe and comfortable.

Kerataconus (usually bilateral) is a progressive thinning of the cornea and is the most common corneal dystrophy. It can cause double or blurred vision, nearsightedness, astigmatism, and increased sensitivity to light.

You  may need specially fitted  custom,soft,rgp, (rigid gas permeable) ,scleral or piggyyback forms  to correct the distortion of the cornea and provide better vision rather than glasses if the disease progresses.​

Corneal collagen cross linking ideally in the mid teens can be considered to strengthen the cornea. 
Using an application of riboflavin (Vitamin B2) eye drops during exposure to ultraviolet (UVA) light, the  exposed deeper layers of the cornea develops bonds between its fibres,followed by a bandage contact lens to aid repair. 
The cause of keratoconus is unknown,likely to be an inherited condition. Some studies have connected keratoconus with allergies such as asthma ,eczema and excessive rubbing.​

KBA design 10.2mm, Epicon 13.5mm or Katt 16.5mm can vault much of this irregularity.  
​We can advise on the material and design based on the optics,health and shape of your eyes and frequency of replacement.​
In advanced cases corneal grafts can be done often ideally between  20 – 45 years of age which then are fitted sometimes with contact lenses.
Different materials vary in  how much oxygen can pass through to the eye, and how moist your lenses stay throughout the day .

​Corneal topography  images and maps the surface curvature regularity as does anterior OCT scanning for a variety of eye conditions. 
In most cases, the cornea stabilizes after a few years without causing severe vision problems. ​​
A small number of people with keratoconus may develop severe corneal scarring or become unable to tolerate a contact lens. For these people, the  corneal transplant may become necessary​

Contact lens fitting requires continued after care.
​Always wash and dry your hands thoroughly before touching your contact lenses Replace your contact lenses at the recommended interval Clean your contact lens case daily and replace your case every month Do not sleep or nap in your contact lenses unless supervised and planned. Water contains microbes that can cause serious eye infection. Your lenses should not come into contact with water: avoid swimming and showering while wearing them Bacteria are present on surfaces all around us. • Only two thirds of people in the general population practice any sort of hand hygiene. • Up to 50% of contact lens wearers are not compliant with hand washing procedures. • Poor hand hygiene is a risk factor of developing microbial keratitis and corneal inflammatory events in contact lens wearers.


There’s currently no evidence to suggest an increased risk of being infected with SARS-CoV-2, the novel coronavirus that causes the disease known as COVID-19, through contact lens (CL) wear. Contact lens wear is safe and can be maintained by healthy individuals. 

However correct hand-washing and strict hygiene practices for CL wearers in order to decrease the risk of eye infections is still very much essential. Contact Lens Wear is a safe activity with low rates of infections or other serious complications, but poor compliance with safe practices can icrease risk.

Contact lenses, solutions and eye drops (where applicable) should be used, worn and replaced as prescribed. Storage case hygiene and care practices should be followed for reusable lenses.
Where possible, Daily Disposable Contact Lenses are advised as they improve compliance and reduce risks of complications in lens wear.

It is advised not to wear contact lenses if a wearer is unwell. This applies in particular to any signs or symptoms of colds and flu, respiratory tract infections, red sore eyes, discharge. Contact lens wear does not appear to increase the risk of developing COVID-19, compared to spectacle lens wearers, or those with normal vision who do not need any corrective devices.  To date there is no known research suggesting any such link or risk.

• It should also be noted that contact lenses provided by leading manufactures are manufactured in sterile conditions and the lenses are safe to wear. The majority of contact lenses provided on the market are in a state ready for wear. Customised lenses should be disinfected before use.
• Contact Lenses obtained from dubious sources, including counterfeit lenses and those offered through unlicensed
premises and providers should be avoided as these may not be sterile or safe to wear.
• Always seek professional advice and consult with your eye care provider.
• Avoid touching your eyes, face, nose and lips as far as possible and avoid eye rubbing.
• There are a few basic messages we can apply to contact lenses. Your eyes should ‘Look Good’, ‘See Good’ and ‘Feel Good’.

  • Proper Handwashing: A Cornerstone of Safe Contact Lens Wear
  • Thoroughly WASH HANDS before;
  •  Handling Contact Lenses and CL cases.
    Applying contact lenses, even for brand new lenses direct from the pack. The aim is to prevent spreading any nasty pathogens (bugs, bacteria, fungi, viruses etc) from hands or fingers to the lens and therefore the eye.
    • The same applies to removing contact lenses from the eye.
  • The US-based Centers for Disease Control and Prevention has issued COVID-19 guidance stating that eyes should not be touched with unwashed hands.

Standardised grading scales are used  for recording and monitoring clinical changes to ocular tissues.
The conditions under which  lenses are purchased, stored and transported should be better regulated as should controls over on line sellers with risks of  counterfeit lenses or repackaged. 
 Never change your lens-care system without oversight as preservative reactions are common and require examination.

As well as the risk of cosmetic contact lenses being worn unsupervised some other  cosmetic eye procedures  have their risks also eg 
Eyelash extensions: If synthetic material fragments from the fake eyelashes corneal abrasions can occur as well as requiring removal
Cosmetic laser procedures: If goggles or shields to protect the eyes are faulty laser light can be detrimental to eye health.
Episcleral tattooing: Dye is injected beneath the conjunctiva to change the white of the eye to a colour of choice. Risks of headaches, light sensitivity, infection, haemorrhages, can result.


Most  lens wearers give up in the first year (because of lack of compliance with follow up normally) but most problems can be overcome as contact lens wear is a provocative test for an individual patient.​
​Insertion and removal is preceded by washing,rinsing and drying hands .
One’s ring or middle finger of your dominant hand is used to insert lens centrally . Removal is by looking up and pulling down your lower eyelid with your middle finger. Using your index finger, slide the lens down to  the white of your eye pinching  the lens between your fingers to remove it.
Storage  is in fresh disinfecting solution in freshly cleaned case depending upon wearing modality.

How to use Hydrogen Peroxide correctly
​Hydrogen peroxide placed directly into the eyes or on your contact lenses can cause stinging, burning, and temporary corneal damage. When using hydrogen peroxide you must follow the disinfecting process with a neutralizer. The neutralizer turns the peroxide into water and oxygen, making it safe to put your lenses back into your eyes.

hydrogen peroxide one step cl disinfectintant
  • Neutralization can be either a one-step or two-step process. The one-step process neutralizes your lenses during the disinfecting stage, while the two-step process neutralizes your lenses after the disinfecting stage.
  • Some storage cases have a neutralizer built-in, making it a simple one-step process. With other cases, a neutralizing tablet that comes with the hydrogen peroxide solution must be added. This is the two-step process.
​Not washing hands with soap and water and drying via lint free towel or lint free cloth prior to touching your lenses is a risk factor for complications. 
​Infrequent replacement of  lens cases, along with poor cleaning of cases, has been linked to serious eye infections in contact lens wearers such as ulcers
An invisible layer called a biofilm can grow in the case and its presence  can make contact lens disinfecting solution less effective at killing germs

​Mixing fresh solution with used solution in its  storing case also  risks  contact lens-associated infections. A multipurpose solution still requires rubbing action and a clean rinse.

​Specific lubricating eyedrops or artificial tears that are preservative free can help wetting of specific lens materials and we can recommend the ideal wearing replacement schedule to avoid the potential contact lens blindness at worst or suboptimal performance and safety.

Saline cannot be used as a disinfecting agent.

See Center for Disease Control & Prevention

For reusable contact lenses, disinfecting Solution will reduce the amount of germs on the lens after each wear, so as to prevent an infection from occurring. For contact lens disinfecting solutions to be effective, they have been tested and must pass the government FDA/TGA requirements to reduce germs but also be safe on the eye. Disinfecting solutions also remove build-up (proteins & lipids) on the contact lens to provide optimal comfort through the wearing schedule of the lens.

Saline does not pass this requirement; it does not contain any ingredients that will reduce the germs that are on the contact lens. It also does not contain any ingredients that will remove the proteins and lipids that stick to contact lenses during the day.

Acanthamoeba keratitis

Often  misdiagnosed as conjunctivitis and is a rare infection by  common water loving amoeba parasite Contact lens induced  abrasions on the eye, can aid  the amoeba to attach when the eye comes into contact with water.
no tap water

Worst cases which can lead to a corneal graft
Vast majority are wearers of soft  lenses  who ignore the risks of rinsing  their lenses in tap water or wear them in the shower.
​In rare cases, the parasite has been known to enter the spinal cord (via the optical nerve) which can lead to death.

Risk of painful  infection is very small but for wearers it is generally recommended that you replace them according to an assigned schedule and  and only rinse and store them in purpose-made contact lens liquid if not the daily modality.

Red and sore eyes can quickly escalate  into corneal ulcers and by using clinical grading scales under microscopic evaluation during your eye examination safe lens wear can be achieved and maintained. ​

​The health of your eyes can be comprimised  so supervision is advisable.

Often trials of a free contact lens in the form of a daily disposable can engender a false sense of security which is why follow up appointments can troubleshoot for potential problems.

Baush and Lomb TerraCycle recycling  used contact lenses and blister packs

Every year in Australia, an estimated 115 million used  lenses and blister packs are sent to landfills. To care for our Planet we support the Bausch + Lomb and TerraCycle recycling program to avoid their ingestion as microplastics with deleterious health effects.
recycling glasses and contact lenses

Too many contact lens wearers are not opting for proper disposal so not being biodegradable can find their way into fish, birds or other animals.
Such recycling means after proper disposal , they can be  shredded, washed and melted down into sustainable raw material that can be used as an alternative to newly manufactured materials.

​All brands  and blister packs can be  sent to via us to TerraCycle an innovative recycling company for this purpose.

Unfortunately a great number of people do not take proper care  or rely on cheap contacts that may not have been stored properly or manufactured accurately.  This can cause infections, irritation, and vision loss. You should never use saliva, only saline, when it comes to moistening lenses. The mouth has lots of bacteria that could quite possibly cause eye infections.​

Contact lens fitting and history

Leonardo da Vinci illustrated the concept of contacts early in the 16th century and by 1887 the first contact lens was manufactured from glass and fitted to cover the entire eye and by 1939 were made in plastic. By 1970 a soft contact lens of a water containing plastic called hydrogel was  introduced and by 1978 so were RGP  Rigid gas permeable lenses that provide sharper vision than soft lenses, which can fluctuate in shape and clarity if they start to dry out. 1981 saw  FDA approval of new soft  lenses for extended (overnight) wear and by 1986 overnight wear of RGP 1987 saw the introduction of disposable soft  and by 1987  RGP contacts  were available in next-generation fluorosilicone acrylate CooperVision clariti 1 day was the first family of silicone hydrogel daily disposables  in 1999. The silicone hydrogel lenses enabled  up to five times more oxygen to reach the cornea than regular hydrogel lenses. Popular brands of silicone hydrogel  lenses include Acuvue Oasys (Vistakon), Air Optix Aqua (Alcon), Biofinity (CooperVision) and PureVision2 (Bausch + Lomb) that can be worn for extended wear or as monthly contact  lenses in suitable eyes as monthy disposables. The science behind incorporating silicone was based on increasing oxygen transmissibility By 2002   Overnight orthokeratology (corneal reshaping) was approved by the FDA The Hypergel material released in 2013 is one material used in trying  to achieve improvement in lenses that can make the eyes feel  dry,  itchy and uncomfortable and can even cause vision problems. Ideally desire All-day comfort , UV protection and resistance to protein deposits ie a lens that mimics the natural eye​ Safe contact lens wear involves being compliant with professional oversight for eye health and vision care. Contact lens fitting is actually prescribing as the lens material interacts with the ocular surfaces. ​Corneal reshaping ( Orthokeratology)  can be induced for different results.   The quality of contact  lenses lenses can vary depending upon how  they are produced. Contact lens deposits and defects can effect eye safety,red eye and infection risk. There are many designs and material options. ​Contact lens prescribing involves creating a valid contact lens prescription, whether new or modifying a previous prescription. A valid contact lens prescription involves services with corresponding fees that are distinct to a general eye examination. A contact lens prescription encompasses parameters including material, base curve, diameter, and power design and water content. Grading scales exist for the eye responses to the provocative test of contact lens wear as many individual reactions can occur. The latest advanced wearable lens technologies are ocular devices for vision providing comfort,safety and convenience.
