How often should I check my vision?

For adults, it is common to have their vision tested every two years. However, if you have vision problems that interfere with your daily activities, such as tiredness and redness of the eyes, photosensitivity or blurred vision, it is advisable to see an optometrist or eye specialist as soon as the discomfort occurs.
In general, visual acuity in adults rarely changes and is more related to age (presbyopia) or poor working conditions. Sudden deterioration of vision can indicate illnesses such as diabetes, high blood pressure, and so on.
As children are still developing, it is recommended that they have their vision checked every year, or every six months, if necessary. Detailed instructions are given to the parent by an eye specialist or optometrist.
