Blunt eye damage can result in retinal bruising and scarring. Tears can form as a result of physical trauma and lead to blinding retinal detachments at any age. Light flashes, floaters, and loss of vision are all symptoms of retinal detachment. Sharp objects such as glass can penetrate the skin and reach the eye. This type of injury may cause only superficial damage to the retina, but it can still lead to retinal tears and bleeding. A doctor will be able to tell if you have been exposed to a sharp object by looking at your eyes. If you have been injured in this way, see a medical professional immediately. Electricity can also cause serious harm to the eye. If you are working with electricity and experience pain or seeing spots before your eyes, remove your glasses or contact lenses before checking your eyes out of concern for being electrocuted. Contact a medical professional immediately if this happens. If you suffer from diabetes, you are more likely to develop conditions that lead to blindness. Diabetic retinopathy is one of these conditions. This condition can lead to severe vision loss if left untreated. Consult with your doctor about how to control your blood sugar levels to prevent diabetic retinopathy from developing in the first place. Smoking can also lead to retinal detachment. If you smoke, stop now.
