Have you recently noticed 'cobwebs' or a little 'fly' infront of your your vision? These 'floaters' often lag behind in the direction of your vision. You may have noticed flashes of light in the periphery of your vision; or even a dark curtain coming over your vision. If so, your practitioner will instill drops to dilate the pupil. This allows your practitioner to examine a wider area of the retina. However, the drops will make you light sensitive for around 4-6 hours. As a result, you should not drive until your eyes return to normal. A sudden onset of floaters and flashing lights are associated with changes to the vitreous jelly inside the eye. Whilst these changes are totally normal for the majority of people, sometimes they can cause a tear to the retina which can lead to a serious complication called a retinal detachment. If you have noticed a dark veil over your vision or even a sudden onset of floaters or flashing lights, please call your eye-care practitioner. With early detection tears can be treated with a laser in order to prevent more serious complications like a retinal detachment.
