TL;DR: Vision should be checked when repeated headaches, blurred vision, reading strain, problems with night driving or a change in an existing prescription appear.
Many people postpone a vision check until they start bringing text closer or taking off glasses to read. Still, small prescription changes can affect work, driving and general comfort long before they become obvious.
Quick Answer
Check your vision if you notice eye fatigue, frequent headaches, blurred text, double outlines, harder focusing, weaker night vision or the need to change the distance of a book or screen.
How to Make a Good Decision
If a symptom repeats for several days or affects driving, work or school, do not wait. For sudden vision changes, pain, flashes or a shadow in the field of vision, contact a doctor more urgently.
- Write down when the symptom appears.
- Bring your existing glasses to the check.
- Pay attention to night driving and glare.
- Do not change your prescription by guessing.
- For sudden symptoms, seek medical advice without delay.
Headache Is Not Always From Vision, but It Can Be a Signal
A repeated headache after reading, computer work or driving can point to eye strain. That does not automatically mean the cause is the prescription, but it is a strong enough reason for a check.
It is especially important to pay attention if the headache always appears after the same visual task.
Night Driving Reveals Changes
Glare from headlights, harder reading of signs and a feeling of insecurity at night are often the first signs that the current correction is no longer ideal. Lens and coating quality also play a role.
If you drive often, a vision check should not be postponed just because you see acceptably during the day.
Children Do Not Always Describe the Problem Clearly
A child may bring a notebook closer, sit near the screen, avoid reading or complain of a headache. This is not always a matter of concentration.
Parents should watch changes at school and in habits, especially if the child already wears a prescription.
