Floaters can have different shapes such as little dots, circles, clouds cobwebs or lines. When a person reaches middle age, this problem is rather common. Floaters are not serious if the retina is not torn. What causes flashing lights is that the vitreous gel pulls on the retina and the patient may see flashing lights or lightening streaks. When this is seen, a patient should contact an ophthalmologist immediately to see if the retina has been torn.
Some people experience headaches and flashes of light with jagged lines or heat waves.
It could be headaches due to migraine. A proper diagnosis by an ophthalmologist in this matter should be made so that this matter can be recognized and treated. This condition occurs due to the lack of secretion of tears produced in the lacrimal gland, which keeps the eyes dry. It causes symptoms such as stinging and scratchiness of the eyes, or irritation of the eyes or even excess tearing with possible difficulty of using contact lenses. A film of tears spread over the eye by a blink makes the surface of the eye smooth and clear.
