A retinal migraine starts at the back of the eye or the retina. Our retinas translate light to the brain with an electrical signal that will then arrange an image for us. One theory for the cause of a retinal migraine is that there is a temporary reduction of blood flow to the area of the retina, and this will cause blurry vision or a blind spot that can get bigger as the migraine goes on. This occurs in only one eye. This reduction of blood flow may induce a twinkling of light or a temporary loss of vision. A retinal migraine can last anywhere from five minutes to an hour, after that vision will go back to normal.
Photophobia, also known as having light sensitivity, is when your eyes are delicate to certain light. It can be sunlight, fluorescent light or incandescent light. Both fluorescent and incandescent lights are common in most buildings. The difference is fluorescent light is made from mixtures of gases creating light and incandescent is from electricity where electricity runs through the wire inside the bulb. Needing to squint often and headaches becoming more frequent may be an indication of light sensitivity.

Do you ever find yourself struggling with blurry vision, eye twitching, headaches and watery or dry eyes? If so, stress may be the culprit. Stress can impact various aspects of our health, including our eyes and vision. In addition to the aforementioned symptoms, stress can also cause dizziness, eye strain, sensitivity to light, eye floaters and eye spasms.
Many medications with long-term use can cause eye problems over time. Common steroid drugs such as prednisone and betamethasone can cause cataracts and glaucoma with years of use. Cataracts cause cloudiness of the lens of your eye, which is the part of the eye that helps us focus on light. Glaucoma is an eye disease that affects the nerve in the back of the eye, which causes peripheral vision loss.
