The retina is a thin, light-sensitive tissue that lines the back of the inside of your eye. It transmits electrical signals to your brain via the optic nerve. The retina’s job is to process the focused light that comes in through your pupil and let your brain convert this information into a picture.

When you consult a healthcare professional, be sure to go over all the medications you’re currently taking. Some medications can cause vision-related side effects.

Regular eye exams can help your healthcare professional determine if there have been any changes to your vision or the health of your eyes.

Several types of eye-related conditions may cause light flashes to appear in the corner of your eye or field of vision. This includes:

Tiny fibers float in the clear vitreous fluid; some are attached to the retina’s surface. When these fibers tug or pull on the retinal surface, it can cause flashes or light sparks from the friction.

The vitreous humor is a clear jelly-like fluid that takes up a large part of the back of your eye. It protects the retina and helps your eye maintain its shape.

A TIA can often be a warning sign of a stroke. That’s why it’s important not to ignore the signs. If you notice any of the following symptoms, get medical attention as soon as possible:

The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat.

A wide variety of issues can cause flashes of light. Some may be related to your eye, and some may be a symptom of another type of condition, such as migraine, epilepsy, diabetes, or TIAs.

Retinal tears or retinal detachment are often characterized by flashing lights, streaks of lightning, or stars in your line of sight. These flashes are often white or yellow and may be more noticeable in a dark room.

The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. Again, this makes it easier to find an object on low power, and then switch to higher power after it is in focus. A common exercise to demonstrate depth of focus involves laying three different colored threads one on top of the other. As the observer focuses down, first the top thread comes into focus, then the middle one, and finally the bottom one. On higer power objectives one may go out of focus as another comes into focus.

When drawing what you see under the microscope, follow the format shown below. It is important to include a figure label and a subject title above the image. The species name (and common name if there is one) and the magnification at which you were viewing the object should be written below the image. All relevant parts of the drawing should be labelled on the right side of the image using straight lines. Lines should not cross. Drawings should be done in pencil, while labels should be in pen or typed. Remember that total magnification is determined by multiplying the ocular x objective.

Flashes of light in the eye are typically not a condition on their own. Instead, they tend to be a symptom of another condition.

A healthcare professional can determine the cause of the light flashes based on the type, duration, and location of these visual disturbances.

The retina knows only one “language,” and that’s light. This means that anything stimulating the retina, including pushing or pulling on the retina, can lead to the transmission of a light impulse – even in a totally darkened room.
