![]() ![]() If you suddenly see multiple dots and lines in your vision coupled with flashes of light then you’ll need to make an emergency appointment. Read: our full guide on what to expect from cataract surgery When to consult your local optician The brain soon adjusts to this phenomenon. ![]() This happens when light hits the new lens implant at an angle that seems to cause a flash in your peripheral vision. If you’ve undergone surgery for cataracts, then you might experience seeing flashing lights. Laser treatment to blast clumps of floaters can also be effective. In most cases, the brain simply tunes out the presence of floaters but eye drops can help. These are small pieces of debris that float around in the gel or vitreous at the back of the eye.įloaters usually become apparent as we age and are most common among people in their 60s and 70s. If you see dots, lines or flashes in your eyesight, particularly when you’re looking at a white wall, then you have floaters in your vision. If the retina becomes detached it must be surgically repaired as quickly as possible to prevent loss of vision. If you notice dots and lines in your vision – known as floaters – or flashes of light then there’s a problem with the retina that can become increasingly serious. Just occasionally, however, it pulls on the retina hard enough to cause a tear. Usually, the gel inside the eye moves around without any problem. If you’re experiencing flashing lights in one side of your vision, then take ibuprofen or paracetamol and lie down in a darkened room with your eyes closed. Here are four possible reasons why you may be seeing flashing lights in your eye and their treatment:įlashes of light are one of the classic symptoms of a migraine. But what causes them and when should you consult a doctor? Most people experience the sensation of seeing flashes of light and, in most cases, they’re harmless. Most flashes are caused when the gel inside the eye changes in some way and pulls on the retina. You may be surprised to learn that they’re nothing to do with what’s going on around you but occur in your eyes and brain. Stephanie Pisano is an optometrist at The Ohio State University Wexner Medical Center.Are you experiencing flashes of light in your vision? Even if you have no change in vision or don’t wear glasses or contact lenses, a yearly dilated eye exam is encouraged to evaluate the health of the retina before any problems develop. If you’re concerned about any lights you see in your vision or have new flashes of light, a thorough dilated eye exam is required. ![]() Retinal tears and detachments are sight-threatening and need to be evaluated immediately by an eye doctor. The retina doesn’t sense any pain or discomfort flashing lights can be one of the first signs that there’s a change in the retina. These flashes are seen intermittently after development of a retina tear or detachment and usually don’t subside until it’s repaired. This tugging can cause a tear in the retina, pulling away from the eyeball and causing a detachment. Retinal tears or detachment and photopsiaįlashes of light, or photopsia, which occur with the eyes open or closed due to a retinal tear or detachment are due to mechanical tugging of the retina. After auras subside, vision will return to normal. Usually, auras precede a headache or migraine and have geometric-associated shapes and shimmering colors. They grow over a course of minutes to cause a scotoma, or blind spot, with your eyes open or closed. Auras generally last from 20 to 60 minutes and start slowly in one area of the vision. Visual patterns or sudden lights in your vision also can be caused by ocular migraines, or auras. Phosphenes will subside quickly, in less than a few seconds, and don’t cause any change to vision. Usually, phosphenes are described as sparks, twinkling lights or pin-prick light shapes that can be brightly colored. Some activities that stimulate the retina in this way include: Phosphenes are generated by the retina after there’s some sort of stimulation, even with the eye closed. The electrical signal is then sent to the brain to provide us with the visual image we see of the world. The retina’s job is to take visual information entering your eye through the pupil and convert this information into an electrical signal. The internal lining of the eyeball is called the retina. ![]() These small lights are usually phosphenes, a visual phenomenon caused by mechanical stimuli resulting in pressure or tension on the eye when the eyelids are closed. But, by the time you open your eyes, they’re gone. You rub your closed eyes, or sneeze, and suddenly notice some flickers or sparks of light in your vision. ![]()
