Think of them as an instant power move. This is about strategy.

For your everyday look, you strategically select natural designs to effortlessly brighten and enhance. For a major moment, you demand attention with vibrant or dramatic shades that completely transform your aesthetic.

The point is: Make every single look a statement. Or don't bother.

Think bigger. This isn't just about "changing" your eye color—that's such a basic way to see it.

This is about completing the look. A Tinacon lens is the final, essential piece that makes your makeup, your outfit, and your entire vibe feel polished and intentional.

It’s the fastest way to get that "main character energy" and the boost of confidence that comes with knowing your look is flawless.

Yes, 100%. At Tinacon, safety isn't just an option—it's our absolute standard.

We only stock top-tier, FDA-approved lenses from the best certified manufacturers. We handle the serious technical stuff, so you can just focus on looking flawless. It’s that simple.

Ugh, the worst. That sandpaper-in-your-eye feeling? We don't know her.

That discomfort isn't a "normal side effect"—it's a sign that the lens just wasn't the right match for you. It's almost always one of two things:

1. The Fit Was Wrong. Lenses aren't "one-size-fits-all." If the Base Curve (BC) was too tight or too loose for your eyeball, it's going to feel wrong. It's like wearing shoes in the wrong size.
2. The Material Was... Lacking. The lens probably wasn't breathable, or it dried out in two hours.

Here at Tinacon, our standards are just... higher. We obsess over getting both right: a perfect fit and premium, all-day materials. You're welcome.

That only happens when you're looking at the wrong lenses.

Truly refined lenses are meant to enhance, not just overwhelm. We, obviously, have the seamless blending styles for that "woke up like this" glow.

And when you do want to command the room? Our dramatic looks are engineered for that, too. We're not one-dimensional.

Ugh, that's messy. A sliding lens is the number one sign that your Base Curve (BC) is wrong.

It means the lens is too "flat" or wide for your eyeball, and it's just... swimming around in there.

Fit isn't optional, it's everything. It's like wearing shoes that are three sizes too big and then wondering why you're tripping. Go check your prescription and make sure the BC value is actually the one you're supposed to be wearing.

Ugh, let's not make this a science project.

Why would you guess? Trying to figure out your "skin undertone" is just... a lot of work. We’d rather you just look good.We already did the hard part for you. That's literally why we made [The Quiz]. Just answer a few obvious questions and we'll show you exactly what works. It’s that easy.

Ugh, sorry. We don't have those in the collection right now. We know, it's a bummer.

It's printed literally right on the box. We put both the "MFG" (that's manufacturing, obvs) and the "EXP" (expiry) right on the packaging. You can't miss it.

It's simple:

• For Dailies: You add one box with your left eye's power to the cart. Then, you add a second box with your right eye's power. Two eyes, two boxes. Done.
• For Monthlies & 6-Month Lenses: We're already ahead of you. The product page literally has separate options for "Left Eye" and "Right Eye." Just select your two different powers before you add to cart.

Just one rule: Know your prescription. Double-check it before you hit "checkout."

It's pretty hard to miss.

When you're at the checkout page, just look for the box that says "Gift card or discount code." Put your code in. Click "Apply."

Honestly, if you clicked a link from one of our exclusive emails, we probably already did the work for you and it's auto-applied. You're welcome.

We take, like, all the important ones.

Visa, American Express, PayPal, Alipay... all the usual suspects. Basically, if it's legit, we probably take it. You'll see the full list when you're checking out.

And yes, it's secure. Obviously.

Let's be real, that's almost never on our end.

It just means your bank is being, like, way overprotective. They’re the ones who flagged and declined the charge, not us.

The fix is simple: Call your bank and tell them to approve the transaction. Or just use a different card. It's usually sorted out in, like, two minutes.

Don't panic; this happens. First, check your spam or promotions folder—sometimes our emails get lost in the drama. If it’s not there, slide into our customer service and we’ll re-send it to you instantly.

We get your order processed in 1-2 business days. We're not here to make you wait.

If your order is still "Processing," then yes. Contact our customer service immediately and we'll fix it for you. No drama.

But if that status says "Shipped," then it's literally out of our hands. The package is already on its way. Your only option at that point is to deal with a return, and you'll have to cover the handling fee. So, move quickly.

The rule is the exact same as changing an order. You have to be fast.

If your order is still "Processing," contact us immediately and we'll handle it. No problem.

If it's already "Shipped," then it's too late. It's literally on its way to you, and you'll have to deal with it as a return once it arrives. So, decide quickly.

We ship from Shenzhen, China.

Why? Because that's the literal global hub for high-tech manufacturing. It's how we stay ahead of the curve and make sure you're getting the absolute freshest, most innovative styles immediately. We're not interested in slow.

That depends entirely on where you live.

We have an entire page dedicated to this. All the costs, shipping tiers, and estimated times for your exact location are spelled out in detail on our Shipping Policy page. We already did the work for you.

This is the easy part.

As soon as your order ships, we literally email you the tracking number and a direct link. Just check your inbox.

Can't find the email? You can check the status yourself anytime right [here on our tracking page].

Ugh, patience.

The tracking link we sent you is the actual source of truth. It updates automatically.

Our standard shipping window is 12-1Full 15 days, just like our policy says. If there's a major, legit delay, our system is already monitoring it. We'll handle it. It's fine.

That's a hard no.

For obvious health and hygiene reasons, we can't take back anything that has been opened or worn. Once you break that seal, they're yours.

...Obviously, this doesn't count if there's an actual quality defect. We're obsessed with our standards, so a real defect is, like, personally offensive to us. If you think there's a quality issue, contact our customer service immediately. We'll look into it, and if it's on us, we'll make it right.

We have a whole policy for this, obviously.

It's all spelled out in detail right here: Click here to view the full Return & Refund Policy.

You really need to read the whole thing. It's the only way to avoid any... unnecessary drama.

And just so we're clear: Contact us before you just send something back. 

It's the exact same rule as a return.

The box has to be perfect. Unopened. Un-touched. We're not playing games with hygiene. We can't resell anything that's been tampered with.

So, here's the playbook:

1. Do NOT send it back yet.
2. Contact our customer service first and tell them what you want instead.
3. We have to, like, check if we even have what you want.

If we do, you'll send the original (perfect, unopened) ones back. After we get them and confirm they're pristine, we'll ship out your new order.

Ugh, as if. That is not our standard.

If you got the wrong thing, or (heaven forbid) something was damaged inside the sealed package, here's the playbook:

1. Contact our customer service immediately.
2. Send us the receipts (literally, clear photos of the issue).

Once we verify it, we will handle it. We will immediately process a full refund or send a replacement.

And no, you're not paying for shipping. Duh. We don't do "imperfect."

Okay, let's talk about how color... works.

A lens is a filter, not a "delete" button. The final look is always a blend of two things: 1) Our lens color, and 2) Your natural eye color.

Our website photos are the actual lens, shot in perfect studio lighting. But we can't control your personal lighting, or the fact that your natural eyes are, like, super dark or super light. That's literally the whole point of a "blend."

Now, if the color is, like, wildly different (you ordered brown and it looks blue), that's a different story. Contact our customer service immediately. That sounds like our mistake, and we'll fix it.

We get it. Finding your absolute perfect shade is a journey.

But as we mentioned, the final color is always a unique blend with your own eyes. And once a seal is broken, our hygiene policy is, like, the unbreakable rule. We can't accept a return on an opened item just because it wasn't the exact vibe you were going for.

We're efficient on our end. Once your return is approved, we process the refund within 24 hours.

After that, the timeline is in your bank's hands. Most institutions take 3-7 business days to post the funds to your account.

If you're past the 7-day mark, that's when you'll want to check directly with your bank, as they'll have the most accurate update.

Lenses first. Always.

This is the pro-tip: putting your lenses in before you apply any makeup is the cleanest, safest way. It ensures no powder, mascara, or oils get trapped on the lens, which keeps your eyes comfortable and your vision clear. It's the standard for a reason.

We've actually dedicated an entire, detailed guide to this. It's the definitive playbook for a flawless, safe, and comfortable experience.

Everything you need to know—from hygiene to handling—is spelled out for you on our Wear & Care page.

We have a firm playbook for this, even with our premium, high-performance materials.

• The Golden Rule (For Pro-Wearers): 8-10 hours is the absolute maximum for daily wear. This is non-negotiable. Your eyes need time to rest and breathe.
• The Starter Rule (If You're New to Lenses): You have to give your eyes time to adjust. Start with 4 hours on your first day. If that feels perfect, you can add 1-2 hours each following day, building up to the max.
• The Most Important Rule: This isn't a "power through it" situation. If you ever feel any discomfort, the answer is always to take them out immediately. Your comfort is the standard.

This is the definitive "Do Not" list. It's not about suggestions; it's about safety.

• 1. Sleeping & Napping: This is the big one. Never sleep, or even nap, in your lenses (unless they are specifically rated for extended wear, which most colored lenses are not). Your corneas need oxygen to stay healthy, and sleeping in lenses cuts off that supply. It's simply not worth the risk.
• 2. Water Contact: Keep them away from water. That means no swimming, no hot tubs, and no showering with your lenses in. Water contains microorganisms that can get trapped behind the lens and cause serious, vision-threatening infections.
• 3. The Wrong Eye Drops: Be smart about this. Never use standard "redness-relief" eye drops or any medicated ointments while wearing lenses. The lens can absorb these chemicals, trapping them against your eye. If you need moisture, only use drops that are specifically labeled "re-wetting" or "for contact lenses."

That's a common signal, and you need to address it immediately. A dry or scratchy feeling just means part of the playbook isn't working. It's almost always one of these:

1. Over-Wearing: You've likely worn them past the 8-10 hour recommended limit. Your eyes need time to rest.
2. Environment: You're in a dry, windy, or heavily air-conditioned space. That can draw moisture from the lens.
3. A "Scratchy" Feeling: This almost always means a tiny piece of debris or makeup is trapped.
4. Solution: Your solution isn't fresh, or it's not the right match for the lens material.

The Fix: For scratchiness, remove the lens immediately, rinse it with fresh solution, and check it. For dryness, try lens-safe rewetting drops first. If the feeling persists, your eyes are done for the day. Take them out.

Blurry vision just means something is off. Don't force it. It's almost always one of these three easy fixes from the playbook:

1. It's Inside Out.This is the most common culprit. It means the lens is flared out (like a plate) instead of being a perfect bowl shape. Take it out, flip it, and re-insert.
2. It's Not Clean.A tiny smudge of makeup, oil, or dust is all it takes to blur your vision. Take it out, rinse it thoroughly with fresh solution, and try again.
3. The Fit Isn't 100% Right.If you've fixed 1 and 2 and it's still blurry, the issue is the fit. This means the Power or Base Curve (BC) you're wearing doesn't exactly match the prescription from your eye doctor.

The Golden Rule: If it's not crisp and clear, take it out. Your vision should be flawless. If it's not, you need to double-check that your prescription is a perfect match.

That's a hard "no." They are called "1-Day" for a reason.

They are engineered for one single, fresh use and are not designed to be cleaned or stored. The moment you remove them, they are considered "done" and must be thrown away.

This is a critical safety rule. Re-using them introduces a major risk of infection because they aren't built to resist protein and bacteria buildup after that first wear.

If you need the convenience of re-wearing your lenses, that's what our Monthly collection is specifically designed for.

The "30-day" clock starts the moment you break the seal on the blister pack, not the first time you wear it.

This is a critical safety rule. The lens material isn't engineered for that, and the solution in your case isn't designed to keep them sterile and safe for that long. That pair is done. You'll need to start with a fresh one—it's the only way to be 100% safe.

Don't panic. That's a common issue, and here's the quick, professional fix. Don't just rinse it; you have to clean it.

1. Remove the lens immediately.
2. Place it in your palm and add a few drops of fresh contact lens solution.
3. Gently rub both sides of the lens with the pad of your clean finger for about 20 seconds. This is the crucial step that lifts the makeup off.
4. Rinse it thoroughly with more fresh solution.
5. Re-insert.

The Golden Rule: If you re-insert it and feel any trace of scratchiness or irritation, take it out. It's not worth it. Discard that lens and start with a fresh one.

This is a non-negotiable: Never.

Tap water is not sterile. It contains microorganisms (like acanthamoeba) that can get permanently trapped on the lens, leading to severe, vision-threatening eye infections. This isn't a "suggestion," it's the #1 safety rule.

Think "clean and dry." That's the entire playbook.

You should store your lens case at room temperature in a dry, hygienic space. The most important rule is to keep it away from excess moisture and steam.

Pro-tip: Your steamy bathroom is actually the worst place to store them, as moisture can contaminate the case. A clean cabinet or a drawer in your bedroom is a much safer, more professional spot.

Every. Three. Months. This is non-negotiable.

Think of your case as a disposable tool for hygiene, not a permanent accessory. Even with perfect daily cleaning, invisible biofilm and bacteria will inevitably build up over time. It's just a fact.

Replacing your case every 3 months is the non-negotiable, professional standard. It's the only way to ensure your routine stays 100% clean.
