If you are having trouble focusing your eyes, you might also experience a range of other symptoms, including headaches and a sensation of feeling off-balance. Because there are several different reasons why you could be having trouble focusing with one eye, you should make an appointment with your optometrist. Reporting any changes in your eyesight as soon as you become aware of them can help you to nip any potential problems in the bud. Read on for some of the most common causes of focusing problems.

Astigmatism

Astigmatism is a condition that can be found in one or both eyes - and it can either be hereditary or caused by damage to your eye. It occurs when your eye's cornea curves unevenly, resulting in blurred vision. Depending on the severity of your symptoms, astigmatism can be treated with corrective lenses (either glasses or contact lenses), or - in some cases - surgery.

Changes in your vision

Whether you already wear corrective lenses or you suspect you may need them for the first time, it is not unusual to require slightly different prescriptions in each eye. If you notice that your vision in one eye is less clear than the other, make an appointment with your optometrist to assess whether or not you may need new glasses or contact lenses. Advice from your optometristYour optometrist will be able to get to the cause of your vision problems and recommend an appropriate treatment depending on your circumstances. Because there are many other reasons why your vision may suddenly appear to be blurrier in one eye than the other, it is important to get a correct diagnosis as quickly as possible.
