Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
A major risk factor for AIR is a history of cancer, especially in paraneoplastic autoimmune retinopathy, where the autoimmune response is triggered by cancerous cells and cancer treatments. Cancer-associated retinopathy is commonly linked with cancers such as lung cancer and breast cancer, which trigger an autoimmune response due to malignant ...
Photic retinopathy is damage to the eye's retina, particularly the macula, from prolonged exposure to solar radiation or other bright light, e.g., lasers or arc welders.The term includes solar, laser, and welder's retinopathy and is synonymous with retinal phototoxicity. [1]
Long-term contact lens use can lead to alterations in corneal thickness, stromal thickness, curvature, corneal sensitivity, cell density, and epithelial oxygen uptake. . Other structural changes may include the formation of epithelial vacuoles and microcysts (containing cellular debris), corneal neovascularization, as well as the emergence of polymegethism in the corneal endoth
The retina is located at the back of the eye. Blue light can induce photochemical damage to the retina by passing through lenses and into the retina. Two primary types of cells contribute to vision formation within the retina: photoreceptors (including rod and cone cells), and retinal pigment epithelium (RPE) cells. [16]
If you can dedicate 10 to 20 uninterrupted minutes a day to light therapy, go with a mask or hair-growing cap (most are hands-free so you can watch TV or scroll your phone).
RELATED: What your eyes say about your health "Since patients oftentimes require multiple treatments and overexposure to this, light can be potentially dangerous to your vision," she continued.
Cancer cells can also cause defects in the cellular pathways of apoptosis (programmed cell death). As most chemotherapy drugs kill cancer cells in this manner, defective apoptosis allows survival of these cells, making them resistant. Many chemotherapy drugs also cause DNA damage, which can be repaired by enzymes in the cell that carry out DNA ...
