Asthenopia crystals are a type of special lenses that are designed to alleviate the symptoms of asthenopia, also known as eye strain or ocular fatigue. Asthenopia refers to a condition in which the eyes become tired and fatigued due to prolonged use, usually caused by activities such as reading, using electronic devices, or working in front of a computer screen for extended periods.
Asthenopia crystals are typically made from a high-quality transparent material with specific optical properties. These crystals are incorporated into eyeglass lenses or applied as a coating on the lens surface. The primary purpose of using asthenopia crystals is to reduce the strain on the eyes by modifying the light entering the eye and optimizing visual perception.
The unique design and properties of asthenopia crystals aim to address specific issues related to eye strain. They may include features such as anti-reflective coatings to minimize glare, blue light filtering to reduce the amount of harmful blue light emitted by electronic devices, as well as magnification or specific lens powers to enhance visual clarity and reduce focusing strain.
By incorporating asthenopia crystals into their eyeglasses, individuals experiencing eye strain can potentially alleviate symptoms such as eye discomfort, blurred vision, headaches, and general eye fatigue. However, it is important to note that asthenopia crystals should be prescribed and fitted by a qualified optometrist or ophthalmologist to ensure appropriate correction and avoid any potential adverse effects.
Overall, asthenopia crystals are specialized lenses or coatings designed to provide relief and improve visual comfort for individuals experiencing eye strain caused by prolonged near work or exposure to electronic devices.
