The Real Truth About Contact Lens Safety: Facts vs Myths

Are contact lenses safe for your eyes? Many people who wear lenses or plan to wear them ask this question. The numbers show that serious eye infections hit one in every 500 contact lens users each year. But contact lenses are a safe way to correct vision for millions of people worldwide - if you use them right.

Your eye doctor must write you a prescription for contact lenses because they're medical devices. This rule applies to all lenses, even the ones that just change your eye color. Taking care of your lenses the right way makes a big difference to your safety. Research shows that poor maintenance can lead to fungal contamination in lens cases. The American Optometric Association knows this well and tells people to get their eyes checked every 12 months to make sure their lenses work safely. This piece will help you tell facts from myths about contact lens safety, so you can keep your eyes healthy while wearing your lenses.

Understanding Contact Lens Safety

Contact lenses give you amazing vision correction. You need to know why they're regulated as medical devices to understand all the safety rules around them. These tiny disks need careful oversight to protect your eyes, even though people use them every day.

Why contact lenses are considered medical devices

The Food and Drug Administration (FDA) classifies contact lenses as medical devices because they touch your eyes directly. This isn't just paperwork—wearing lenses incorrectly can harm your eyes badly.

The Federal Food, Drug, and Cosmetic Act lets FDA regulate contact lenses as Class II or Class III medical devices. This shows how risky they can be and why you need proper fitting, instructions, and care.

You can't just buy contact lenses over the counter—you need a valid prescription, even for cosmetic lenses that don't correct vision. And with good reason too: everyone's eyes have a unique shape and needs. A lens that fits one person perfectly might hurt someone else's eyes.

Manufacturers in the US must:

• Register with FDA each year

• Add each lens type to FDA's database

• Submit required documents (510(k) or PMA based on lens type)

• Test for sterility and biocompatibility

• Use Unique Device Identifiers for tracking

These rules make sure the lenses that reach your eyes are completely safe.

How safe are contact lenses when used correctly?

Contact lenses are safe and work well when you use them right. About 45 million Americans wear them, which shows how safe and popular they are. All the same, bad habits with wear and care can cause problems.

The Centers for Disease Control and Prevention (CDC) says serious eye infections hit up to one in 500 contact lens users yearly. The US has seen several outbreaks of Acanthamoeba keratitis and Fungal keratitis since 2006—both can make you lose vision or go blind.

People can prevent most contact lens problems. Research shows many contact lens wearers don't take care of their lenses properly. Simple safety steps can stop infections and other issues.

Your lens safety depends on:

1. Professional oversight - See your eye doctor yearly to check your prescription and eye health

2. Proper hygiene - Always wash your hands before touching lenses

3. Correct cleaning procedures - Use the right solutions and never water

4. Following wear schedules - Don't wear lenses too long or while sleeping 

5. Avoiding water exposure - Keep lenses away from tap water, pools, and hot tubs

Take your contact lenses out right away if your eyes get red, hurt, feel irritated, see blurry, become sensitive to light, or tear up too much. These signs might mean you have an infection that needs quick medical help.

Contact lens safety boils down to treating them like the medical devices they are. You can enjoy all the benefits of contact lenses with minimal risk by following your doctor's advice and keeping good habits.

Benefits and Risks of Wearing Contact Lenses

Making informed decisions about your eye health requires a full picture of both the advantages and potential risks of vision correction options. A closer look at contact lens wear reveals much more than simple vision correction benefits.

Benefits of contact lenses over glasses

Contact lenses have become a preferred choice for about 140 million users worldwide. These tiny lenses that conform to your eye's curvature offer several advantages over traditional glasses:

Your vision feels more natural with contacts compared to glasses. The lenses move with your eyes without any physical barriers to block your view. You get about 15% wider peripheral vision than glasses, which reduces blind spots and distortions. This expanded field of view proves especially valuable if you have an active lifestyle or play sports.

Contacts work better than glasses in challenging weather conditions. You won't deal with foggy lenses in cold weather or water droplets during rain. Athletes can perform without worrying about glasses falling off during intense activities like gymnastics or cheerleading.

Many users love how contacts are practically invisible on their eyes, giving them a natural look without frames. You can even try colored contact lenses to change your eye color temporarily.

Common risks and how to avoid them

Contact lenses come with their share of risks despite their benefits. Each year, serious eye infections affect up to 1 in 500 users. Poor care and handling cause most of these problems.

The most significant concerns include:

• Microbial keratitis: A serious eye infection caused when germs invade the cornea, which can lead to blindness or require corneal transplant in severe cases

• Corneal ulcers: Open sores in the outer layer of the cornea, usually caused by infections

• Dry eyes and allergies: Common complications that may cause discomfort

• Corneal abrasion: Scratches on the cornea often resulting from improper handling

You can prevent most of these complications with proper care. Studies show that 40%-90% of contact lens users don't follow proper care instructions. This fact highlights why following safety guidelines matters so much.

To minimize risks, stick to these key practices:

Clean your hands really well before touching your lenses. Use proper cleaning solutions for reusable lenses - never tap water or homemade solutions. Get a new lens storage case every three months.

Daily disposable lenses offer a great way to reduce contamination and deposit buildup. Never sleep with contacts unless they're designed for overnight wear - this step alone significantly reduces infection risk.

Take your contacts out right away if you notice discomfort, excess tearing, light sensitivity, itching, burning, redness, blurred vision, swelling, or pain. These symptoms might signal an infection that needs immediate medical attention.

Note that eye problems can develop quickly, and you shouldn't try to judge their severity yourself. Remove your lenses and call your eye doctor if you're unsure. Regular checkups every 6 to 12 months help maintain healthy eyes and ensure your lenses fit properly.

Types of Contact Lenses and Their Safety Profiles

Contact lens materials and designs come with different safety profiles and benefits. Your eye health and overall experience depend on choosing the right type that fits your needs.

Soft vs rigid gas permeable lenses

Soft contact lenses rule the market because they feel comfortable right away. These lenses use flexible plastics that let oxygen reach your cornea and adapt to your eye's shape. Most people get used to them in just a few days. Athletes and sports enthusiasts love them since they stay in place during physical activities.

Rigid gas permeable (RGP) lenses offer several safety benefits:

• Only 1.2 cases of microbial keratitis per 10,000 wearers each year

• Better tear exchange (10-20% compared to 1-2% with soft lenses) helps remove harmful organisms

• Less than 1% water content versus 24-70% in soft lenses reduces microorganism survival

RGP lenses give you clearer vision, especially if you have astigmatism or keratoconus. On top of that, they let more oxygen reach the cornea as tears flow under the lens. New users should expect a longer adjustment period—possibly weeks instead of days. These lenses might pop out more easily than soft ones.

Daily disposables vs reusable lenses

Daily disposable lenses go in the trash after one day's use. You won't need cleaning solutions or storage cases. This schedule cuts down infection risks by stopping the buildup of proteins, lipids, and calcium from your tears.

Monthly disposable lenses last up to 30 days but need nightly cleaning and proper storage. They cost less upfront—about $20 monthly compared to $30-60 for dailies. Yet, cleaning solutions add up to $150-200 yearly.

Daily disposables give better protection against infections because they're always clean when you put them in. Kids and people with allergies find these lenses especially helpful .

Specialty lenses: toric, multifocal, and colored lenses

Toric lenses fix astigmatism by using different lens powers in various parts. The complex design makes them pricier than standard lenses.

Multifocal contact lenses help you see both far and near objects. People over 40 with presbyopia benefit from these the most. Both soft and rigid materials work, but they need precise fitting.

Colored contact lenses look great but need extra care. The dye might reduce oxygen flow to your cornea. Research shows that colored contact users face 16 times higher risk of keratitis than regular lens users. The colored parts often have rough surfaces where bacteria and Acanthamoeba stick more easily.

Whatever type you choose, you'll need a valid prescription and proper care to keep your eyes healthy.

Essential Contact Lens Care Tips

Your contact lens care habits are the foundations of eye health. Studies reveal that only 1% to 50% of contact lens users follow recommended care practices fully. Poor care habits can damage your eyes permanently, even with occasional proper procedures.

Proper hygiene and handling

You need clean hands to touch your lenses. Wash your hands really well with antibacterial soap and dry them with a lint-free towel. Stay away from lotions or moisturizing soaps because their residue can get on your lenses.

Put your contacts in before applying makeup and take them out before removing makeup. A consistent routine helps you remember all critical care steps and lowers contamination risks.

Cleaning and storing your lenses

The "rub and rinse" method works best to clean reusable lenses—even with "no-rub" solutions. Rub each lens gently with your index finger in your palm for about 20 seconds per side, then rinse it with fresh solution.

Your lenses should never touch tap water, saliva, or homemade solutions because they can introduce harmful bacteria. Fresh solution is a must—never "top off" old solution in your case.

Store your lenses safely by following these four steps:

1. Empty all old solution from your case

2. Rinse the case with fresh contact solution (never water)

3. Allow the case to air-dry upside down on a clean tissue

4. Replace the case every three months

When to replace your lenses and case

Different lenses need different replacement schedules:

• Daily disposables: Replace after a single day's wear

• Weekly disposables: Replace every 1-2 weeks

• Monthly disposables: Replace every 30 days

• Reusable lenses: Can last up to a year with proper care

Contact lens cases become homes to microorganisms at rates between 24% to 81%. You should replace your lens case every three months to stop biofilm formation—a protective layer that makes bacteria resistant to cleaning solutions.

Contact lenses and solutions come with expiration dates you must follow. Expired lenses can break down, grow bacteria, and fail to correct your vision properly.

When Contact Lenses Become Unsafe

Contact lenses are generally safe, but they can cause problems under certain conditions. You can protect your vision and prevent serious complications by spotting warning signs early.

Signs of eye irritation or infection

Your eyes will tell you when something's wrong. Here are the signs you shouldn't ignore:

• Blurry or fuzzy vision that stays even after you blink

• Unusual redness of the eye or surrounding area

• Pain or discomfort that continues after taking out your lenses

• Discharge or pus from your eye

• Excessive tearing or watery eyes

• Light sensitivity (photophobia)

• Feeling like something is in your eye after removing the lens

These symptoms might point to keratitis—the most common infection you can get from contact lenses. Your cornea could get scarred from keratitis, which affects your vision forever. In fact, some contact lens infections can lead to severe vision loss or blindness if you don't treat them.

What to do if a lens gets stuck

Your contacts might stick to your eye if they're too dry or if you sleep with them. Here's what you can do:

1. Use lubricating eye drops to moisten the lens

2. Look down and massage your upper eyelid gently

3. Pull your lower eyelid down carefully to find the lens

4. Don't use sharp objects or too much force

Stop trying if the lens won't come out. Also, don't put in another contact lens while looking for a lost one—you could scratch your cornea.

When to stop wearing lenses and see a doctor

Take out your contacts and call your eye doctor right away if you notice:

• Any infection symptoms that stick around

• Pain that gets worse after removing your lenses

• Vision changes that happen suddenly

• Corneal ulcers (open sores on the cornea)

Don't wait to get help because eye infections can get worse faster. Take your contact lens case to your appointment—doctors can test the lenses to find out what's causing the infection.

Note that sleeping in contacts raises your infection risk significantly unless they're made for overnight wear. You should also avoid wearing contacts in swimming pools, showers, or hot tubs. Non-sterile water can expose your eyes to harmful bacteria and amoebae.
