Like many people, I’ve been wearing corrective lenses for years. By now, wearing contacts or glasses on a daily basis is second nature, but sometimes, dealing with poor eyesight can just be a pain in the ass. Here are nine inconveniences that glasses or contacts-wearers know all too well.

1. Sleepovers

Whether you’re spontaneously crashing at a friend’s for the weekend or ending up at someone else’s place after a night out, nothing is more of a nightmare than having contacts in and no place to put them (especially if the person you’re staying with isn’t a contacts-wearer). Do you leave them in your eyes overnight? Throw them out? Run to the nearest drugstore to buy a case and lenses? This is always a struggle.

2. Contacts falling out at the worst times, in the worst places

The worst experience of this I’ve ever had was dancing at a football game (I used to be on the spirit squad at my university), and BOTH my contact lenses fell out at the same time, while I was dancing in front of thousands of people. I couldn’t see anything and had to go the rest of the game without clear eyesight. Convenient, right?

3. Glasses fogging up in cold weather

If you've ever walked into a warm building after being outside in freezing cold weather, you know exactly what I'm talking about.

4. Headaches

Nothing is worse than the excruciating headache that comes on after going too long without clear vision.

5. Wearing contacts on sleep-deprived eyes

More pain. Putting contact lenses in your bloodshot, dry eyes the morning after a late night of studying, work or an evening out brings nothing but stinging pain and even MORE bloodshot eyes. No, I don’t have pink eye, thank you very much.

6. Breaking or losing your glasses, or running out of contacts

We’ve all been there. Maybe you sat on your glasses (like I did last month) or misplaced them. Maybe you’re completely out of contacts and are waiting for your 1-800-CONTACTS order to be delivered. Whether it’s one or the other, or both, going without comfortable eyesight for any period of time is the last thing you need.

7. Getting ANYTHING caught in your eye while wearing contacts

…and I mean anything. Makeup, shampoo, dust, hair, dirt… whatever it may be, getting virtually any substance stuck in your eye while wearing contacts is devastating. Be prepared for nothing but searing pain that can only be resolved by 1. Removing your contact, 2. Cleaning your contact, 3. Rinsing your eye and 4. Putting the contact back into your irritated eye. Such a frustrating process.

8. Paying for solution, cases, frames, lenses, optometrist appointments, etc.

Especially as a college student, that extra amount of money spent on eye maintenance can add up, like needing to add an extra $10 to your grocery bill for contact solution or having to visit the optometrist after your prescription expires (when it feels like you just had an eye doctor appointment).

Speaking of that, nothing is more frustrating than paying for an eye appointment only to find out that your prescription is exactly the same.

9. Falling asleep in contacts

Again, we’ve all been there. I think this takes the cake for the biggest struggle of wearing contact lenses. Nothing is more terrifying than waking up and attempting to open your dry, crusty and irritated eyes only to realize that you completely forgot to take your contacts out before bed.
