Flashes of light in the periphery of your vision can indicate a tear at the back of the eye known as a retinal tear or detachment. If you see a shadow on the side of your vision this is even more concerning and means that part of the retina has already detached. This requires immediate attention by an ophthalmologist/eye surgeon. You can call your optometrist to help get you an appointment or get them to check that it is a tear or detachment and that you do indeed need to be referred on right away. If you in a remote area, then go to the closest clinic or hospital. If this condition is left, you can lose all your vision! Time is of the essence and is an indication of the end prognosis.

You can also get a lens with ARC and Blue –Control (Refer to Question 6). Be aware that there is different quality ARC’s on the market. Cheap ARC spectacle lenses can peel and do not make the lens clearer.
Rosewall-McCarthy Optometrists uses Hoya Blue Control lenses. Blue Control is a glossy coating with a slight blue sheen which helps to neutralise the blue light emitted by LCD and LED screens, preventing eye fatigue, eye strain and even sleeplessness. It keeps the eyes in better condition, offering more comfortable and relaxed vision and a better contrast perception when using every day digital devices.
