Refractive errors are usually corrected with glasses or contact lenses which can provide clear vision by adjusting the way light is focussed on the retina (the back layer of the eye). In cases of marked anisometropia, where disparities in image size hinder clear vision and can cause double vision in the brain’s visual centres, contact lenses would be a more suitable option. Night lenses or refractive surgery can be viable alternatives for certain types of refractive errors.
For cases involving amblyopia, interventions such as patching or blurring the vision in the stronger eye may be recommended to encourage the use of the weaker eye and surgical correction may be necessary for squints, where one eye is misaligned.
Regardless of the chosen approach, proactive vision testing for early diagnosis, coupled with appropriate treatment, can lead to improved vision quality and a healthier visual system.
Additionally, lifestyle changes, especially for individuals who spend extended periods at a desk, can contribute to reducing symptoms associated with refractive errors. These adjustments may involve optimising posture, increasing hydration, improving lighting and ventilation, and taking regular breaks (following the 20:20:20 rule). Your optometrist will be able to advise you if any of these simple modifications could be beneficial for you.
