Fluorescent lamps with magnetic ballasts flicker at a normally unnoticeable frequency of 100 or 120 Hz (twice of the utility frequency; the lamp is lit on both the positive and negative half-wave of a cycle). This flickering can cause problems for some individuals with light sensitivity [1] and are
The retina lines the inside of the eye. It is light-sensitive and communicates visual messages to the brain. If the retina detaches, it moves and shifts from its normal position. This can cause photopsia, but can also cause permanent vision loss. Medical attention is needed to prevent vision loss.
Phytophotodermatitis may be aggravated by the additional levels of ultraviolet light emitted by compact fluorescent light. Patients undergoing photodynamic therapy are at additional risk of adverse photosensitive reactions caused by compact fluorescent light. One cause of cataracts is exposure to ultraviolet light. Provided the level of UV ...
A test called flourescein angiography uses a special dye and camera to study blood flow in the back layers of the eye. When a person has multifocal choroiditis (MFC), lesions in the eye will appear as fluorescent spots. Visual field tests may also show an enlarged blind spot or a decrease in visual clarity.
Astigmatism, a disorder that affects how the eyes focus light, can be exacerbated at night. Blurry vision and headaches are symptoms of astigmatism. Why astigmatism causes blurry vision ...
Optic neuritis: Inflammation of the optic nerve from infection or multiple sclerosis may cause blurring of vision. [14] There may be pain while moving the eye or touching it through the eyelid. [14] Stroke or transient ischemic attack; Brain tumor; Toxocara: A parasitic roundworm that can cause blurred vision. [15] Bleeding into the eye
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
People with hyperopia have blurry vision when viewing near objects because the eye is unable to focus the light sufficiently. This can be corrected with convex lenses, which cause light rays to converge prior to hitting the cornea. [13] Presbyopia: When the flexibility of the lens declines, typically due to age. The individual would experience ...
