Regular eye tests are extremely important for a variety of reasons. The most obvious one is that your vision can be improved with an up to date prescription.
Your optician will decide the period between your eye tests which can be range from 6 months – 2 years depending on age and the condition of your health.
Another reason why regular eye tests are important is because they can detect underlying health conditions such as diabetes, glaucoma and high cholesterol. If these conditions are suspected by the optician then they will refer you to your GP for a further check.
