The human eye is often compared to a camera: light enters through the pupil; is focussed by a lens onto the retina (the film) at the back of the eye where images are formed and then sent to the brain for processing (developing).

If issues occur in the focussing system then the images formed on the retina are blurry, these issues are caused by refractive errors.

Kosmac & Clemens Optometrists will determine if any refractive errors are causing issues with your focussing and will recommend appropriate solutions. Optical glasses, prescription sunglasses, contact lenses and even eye exercises are all options to help correct focussing issues.
