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.
Long-term systemic Immunosuppressive therapy is the main treatment of cancer-associated retinopathy. [5] It can be treated with a combination of chemotherapy and immunosuppression. [2] Although tumor removal and cancer regression may result in a decrease in circulating autoantibodies, this does not influence CAR progression. [8]
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
Luckily, both skin cancer and premature aging are preventable with the proper precautions, like using a sunscreen, and you can protect your eyes with the right UV-blocking sunglasses. 8 Sources of ...
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]
Radiation retinopathy is damage to retina due to exposure to ionizing radiation. Radiation retinopathy has a delayed onset, typically after months or years of radiation, and is slowly progressive. In general, radiation retinopathy is seen around 18 months after treatment with external-beam radiation and with brachytherapy.
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.
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]
