One method is to fashion a simple pinhole camera.
If you really need to look at the sun, there are simple and safe ways to do so. These typically become apparent when a person is over 50, but if you’re outdoors a lot or don’t wear eye protection it can happen earlier. Once again, it’s the UV light that’s the problem, resulting in corneal sunburn, cataracts and growths on the eye surface.

They should be able to establish the degree of damage, if any, and advise you how to best manage your recovery.Įven if you haven’t been actively sun-gazing, it’s important to note that damage can accumulate over many years of sun exposure. If you think you may have overdone it looking at the sun or other bright light, it’s important to get checked by an optometrist or other eye care professional. Others never fully recover complete vision, and continue to experience vision problems such as blurriness or spots.

Most people who experience solar keratitis and solar retinopathy make a full recovery but, depending on the level of damage, this can take up to 12 months. If you suspect you have eye damage make an appointment with your eye doctor. It’s often not until several hours (or even days) later, when people find their eyes hurt, their vision is blurred or that dark or yellow spots are affecting their sight that they realise damage has occurred. The retina does not have any pain-receptors, so you won’t feel the damage being done. It destroys the rods and cones of the retina and can create a small blind spot in the central vision, known as a scotoma. This occurs when UV light literally burns a hole in the retinal tissues. More serious damage is known as solar retinopathy. This results in light sensitivity and pain, with symptoms generally showing up within 24 hours of exposure. Short-term damage can include sunburn of the cornea-known as solar keratitis. When you stare directly at the sun-or other types of bright light such as a welding torch-ultraviolet light floods your retina, literally burning the exposed tissue. But if it’s cloudy or hazy, or there’s a solar eclipse taking place, then looking at the sun seems easier and feels less painful. Is this really true or are they repeating an old urban myth?Įven a quick glimpse of the sun is usually painful and difficult, so our natural instinct is to immediately squint and turn away. They threaten our retinas will burn up and we'll be blind forever. Parents always warn us never to look directly at the sun.
