New to contact lenses

Starting, suitability and the questions that come before your first fitting.

Can anyone wear contact lenses?

Many people can wear contact lenses, but they are not suitable for everyone or every eye. A professional contact lens examination and fitting should determine whether lenses are appropriate for you and identify the exact product to use.

Do I need to see an optician or eye care professional before trying contact lenses for the first time?

Yes. Start with a professional contact lens examination and fitting. It checks whether contact lenses are suitable for your eyes, identifies a specific lens and teaches you how to insert, remove and care for it.

Can I use my glasses prescription to choose contact lenses?

No. A glasses prescription is not a contact lens prescription, and contact lens selection involves the lens model, fit and lens-specific values as well as power.

Understand why contact lens values are different

Do contact lenses hurt?

Contact lenses should not normally hurt when the lens is suitable, correctly fitted and worn as instructed. Remove the lens and seek professional advice if pain or significant discomfort continues.

Is it difficult to put contact lenses in, and how long does it take to learn?

It can feel unfamiliar at first, but many people find it becomes easier with practice. How long it takes varies from person to person. A first fitting should include instruction on safe insertion and removal.

Can you put a contact lens in inside out?

Yes. A soft contact lens can be turned inside out and inserted the wrong way round. This is usually not harmful if it happens briefly, but the lens may feel uncomfortable, move more than usual or give blurred vision. Remove the lens, check its shape, turn it the right way round and reinsert it.

To check the lens, place it on the tip of your finger. When it is the right way round, it should form a smooth bowl shape with the edges pointing upwards. If the edges flare outwards like a shallow saucer, the lens is probably inside out.

Some lenses also have orientation markings. For example, some ACUVUE contact lenses use a small 1-2-3 marking that appears in the correct order when the lens is the right way round.

At what age can children or teenagers start wearing contact lenses?

There is no single age that is right for everyone. Children and teenagers can wear contact lenses when an eye care professional has assessed and fitted the lenses and the wearer is mature enough to insert, remove and care for them safely. Age alone does not determine suitability, so a 15-year-old, for example, may be able to wear contact lenses if these conditions are met.

Can I wear contact lenses only occasionally, for example for sport or exercise?

Yes. Contact lenses can be fitted for occasional use, including sport, exercise or selected events. Use only the exact lens fitted for you and follow its wearing and replacement instructions. Appropriate eye protection may still be needed for some sports.

Can I wear contact lenses if I am over 40?

Often, yes. Multifocal and other contact lens options may help when near focus changes with age, but the suitable lens must be assessed and fitted for you.

Can I wear contact lenses if I have astigmatism?

Often, yes. Toric contact lenses are designed to correct astigmatism. The exact lens model, cylinder (CYL), axis (AXIS) and other values need to be fitted for your eyes, so use the lens and values recommended for you by an eye care professional.

Understand CYL and AXIS

Can I wear multifocal contact lenses?

Often, yes. Multifocal contact lenses can provide correction for both distance and near vision for people with presbyopia. The exact lens model and ADD value need to be fitted for your eyes, so use the lens and values recommended for you by an eye care professional.

Understand ADD and multifocal lens values

Prescription & lens parameters

Find and understand the exact product and values you need to reorder.

Do I need to upload a prescription when ordering from Netlens?

No. Netlens does not require a prescription upload when you order. You should still use a current contact lens prescription and order the exact lens model and values fitted or recommended for you.

See how to order contact lenses

Where can I find my contact lens values?

The product name and values are normally printed on your current contact lens box and often on each blister pack. They may also appear on your contact lens prescription.

Understand your contact lens parameters

What do SPH/PWR, CYL, AXIS, ADD, BC and DIA mean?

SPH or PWR is lens power. CYL and AXIS describe astigmatism correction, ADD is used for multifocal correction, BC is base curve and DIA is lens diameter.

See each contact lens parameter explained

Why can’t I select BC or DIA for some contact lenses?

Some lens models are made with one fixed base curve or diameter. When there is only one available value, there is nothing for you to select.

See how fixed BC and DIA values work

Can my right and left eye have different values or use different contact lens models?

Yes. Enter the prescribed values for each eye separately. If you have been fitted with different contact lens models for your two eyes, add each product separately and use the correct values for the corresponding eye.

See how to order for two different eyes

Can I switch to another contact lens if the values look similar?

No, not on the basis of similar values alone. Different lens models can use different materials, designs and fitting characteristics, so ask an eye care professional before changing products.

Can Netlens tell me which contact lens I should choose?

Netlens can help you find products and understand the ordering process, but it does not perform a professional first fitting or decide which lens is clinically suitable for your eyes.

My optician uses a different product name. How do I find the manufacturer’s lens?

Some opticians sell a manufacturer’s lens under another product name. Compare it with the Netlens optician-brand guide, then make sure the manufacturer product and all values are an exact match.

Find your optician’s lens under the manufacturer’s name

What should I do if one of my prescribed values is not available?

First check that you selected the exact lens model. Do not choose the nearest value; ask your optician or eye care professional before ordering.

Ordering & products

Practical help with products, pack sizes and placing the right order.

How do I order contact lenses from Netlens?

Find the exact contact lens model you already use, enter the values for each eye, choose the number of boxes and check every selection before completing checkout.

See the step-by-step ordering guide

How many boxes should I order?

It depends on the pack size, how often each lens is replaced and whether both eyes use the same product and values. Work out the quantity for each eye separately before ordering.

See how contact lens pack sizes work

Does a 30-pack contain 30 lenses or 30 pairs?

A 30-pack contains 30 individual lenses, not 30 pairs. If you use daily lenses in both eyes, one 30-pack for each eye normally covers 30 days.

See more contact lens pack-size examples

Can I reorder the same contact lenses I bought previously?

Yes. Use the exact model and values from your current lenses or previous order, and check that the information is still current before completing the reorder.

See the checks to make before reordering

I cannot find my contact lens model. What should I do?

Check the complete manufacturer and product name on your current box. If your optician uses another name, use the optician-brand guide; otherwise contact customer service for help finding products available on the site.

Wearing, care & safety

Short safety answers for common situations. Persistent or significant symptoms need professional advice.

Can a contact lens get stuck or go behind my eye?

A contact lens cannot pass behind the eyeball. It can move under an eyelid or become dry and difficult to remove. Do not force it or use sharp objects; follow the removal technique you were taught and seek professional help if you cannot remove the lens.

Can I sleep in contact lenses?

Some contact lenses are approved for overnight or extended wear, but sleeping in contact lenses increases the risk of eye infection. Only sleep in the exact lens if it is approved for overnight wear and an eye care professional has advised that it is suitable for you.

Can I shower while wearing contact lenses?

It is best to avoid getting tap water in your eyes while wearing contact lenses, as water can contain microorganisms that may increase the risk of eye infection. If you shower with your lenses in, keep your eyes closed when water is running over your face and avoid direct contact between the lenses and water. If your lenses do come into contact with water, remove them afterwards. Replace daily disposable lenses, or clean and disinfect reusable lenses before wearing them again.

Can I swim while wearing contact lenses?

The safest option is to remove your contact lenses before swimming, as water can contain microorganisms that may increase the risk of irritation or infection. If you do swim with contact lenses, wear tight-fitting swimming goggles to minimise contact with water. Daily disposable lenses should be replaced after swimming, while reusable lenses should be cleaned and disinfected thoroughly.

Can I rinse contact lenses with tap water?

No. Do not rinse or store contact lenses in tap water. Use the care products and method recommended for the exact lens.

Can contact lenses cause eye infections?

Contact lens wear can be associated with eye infection, particularly when lenses are used or cared for incorrectly. Follow hygiene, wear and replacement instructions and act promptly if symptoms develop.

How should reusable contact lenses be cleaned and replaced?

Clean, disinfect and store reusable lenses with the recommended lens-care system and fresh solution, and replace them according to the schedule for the exact product. Never use tap water or top up used solution, and do not deliberately extend the replacement period.

What should I do if my eye becomes red, painful or unusually sensitive to light?

Remove the lens and do not reinsert it. Seek prompt professional advice, especially if you have significant pain, redness, light sensitivity, discharge or a sudden marked change in vision.
