A vision level of 6/18 means that you can see clearly at 6 meters what a person with normal vision can see clearly at 18 meters. In simple terms, your distance vision is weaker than normal, which is commonly seen in myopia (short-sightedness). People with 6/18 vision may have difficulty seeing distant objects clearly, such as road signs, classroom boards, television text, or faces from far away, while near vision is usually better. Myopia occurs when the eye focuses light slightly in front of the retina instead of directly on it, causing distant objects to appear blurred. In most cases, vision can be corrected very well with properly prescribed spectacles or contact lenses, and many people achieve normal vision after correction. A detailed eye examination by an ophthalmologist can determine the exact spectacle power needed. It is also important to have regular eye check-ups, especially if the eye number is increasing, because untreated or progressing myopia can sometimes cause eye strain, headaches, or difficulty in daily activities. Maintaining proper lighting while reading, taking breaks from long screen use, and spending some time outdoors may help reduce eye strain and support overall eye comfort.
