How do i let my parents know i need glasses?!

Sounds like your farsighted. Another term for that is hyperopia. Maybe try to tell you parents that you have hyperopia and need glasses to correct it.
If you go to an optometrist or an ophthalmologist, they will preform the necessary tests to find your prescription. Chances are you'll need glasses with bifocals.
Good luck!!!

College.

Have the school nurse do it. Go to the school nurse and tell her you have a headache and you can't read close up, and she'll call your parents and get them to take you to the eye doctor. It's neglect if they don't! So let the nurse fight the battle for you. You can similarly enlist your teachers. Tell them you need glasses and your parents won't get them for you so you can't do the homework until they take you to get glasses.

Explain to them that there's such thing as "near-sighted" and "far-sighted". For example, I'm near-sighted. I can see things nearby but I couldn't tell you if there's a stop-sign 50 feet away. You sound like you're far-sighted. If you're really desperate, try the reading glasses at any local pharmacy or convenience store. Embarrassing, maybe, but that might drive home the point that you honestly feel you have a vision problem. Does your family have health insurance? If so, ask if you could just get an eye exam, not necessarily buy glasses. Maybe if a certified professional can tell them exactly what you're trying to say, they'll finally believe it.

Three possibilities:

Ask for Grandma's help. She is right.

Go see your school nurse and request an eye exam. Your parents will get a copy of the result.

Try out the reading glasses available in most drugstores. They come in several different strengths and they are not too expensive.

Just come out and say mom,dad I need reading glasses. Tell them about the headaches. The reason I telling you this is because I needed glasses for reading and didn't get them for the longest time. Now my eyes are bad because all of the strain I put on them. Now I wear glasses all the time.

Just tell them you need glasses to read OR you could just go to the drugstore and get the glasses yourself (glasses you get from the drugstore are used exclusively for reading and other close work and you don't need a prescription to get them).

Me!

Well you just answered your own ? tell them you always squint up close when reading and you get headaches if not you can always just make it sound worse than it is so you basically have to go to the eye doc

Just say that it is difficult to read up close. While much less common in teenagers, it is possible that you may need glasses for reading. Just ask your parents to take you.

Maybe sort of fail at reading at something in class, then your teacher will find out you need glasses, and she might bring it up in an interview with your parents or something,

just go to a store try on some eye glasses and see which ones work seek em in the cart wink wink
Dollar tree has eye glasses for a dollar if their is one in your area

my brain

"Mom, I've been having a lot of trouble reading anything close up, and it gives me headaches. What do you think about this?....Someone said I may need glasses."

Tell them the truth...you can't see/read up close and you get headaches.

I think the teacher must have let my parents know I was having trouble reading.

What is wrong with flat out saying HEY MOM AND DAD I NEED GLASSES?
