Do you wear glasses or contacts? If so, you probably make periodic visits to the optometrist. Here you will have checkups and make sure your eyes are in good condition. They'll also give you a higher prescription for glasses or contact lenses as necessary. If you deal with this expense, you know that it can add up quickly.
Even if you don't have classes or contacts, that is no reason to skip the eye doctor visits. It's one thing to go less frequently, but it is another to go 10 or 20 years without going to the eye doctor. You shouldn't wait until you can't see well to get your eyes checked. That could cause more damage to your eyes. Also, you could have and I disease and not even know it. Don't take that chance.
