      1. Single Vision Lenses: These lenses have the same prescription across the entire lens and are used for correcting one type of vision problem, such as nearsightedness, farsightedness, or astigmatism.
      2. Bifocal Lenses: These lenses have two different prescriptions in one lens, usually separated by a visible line. The top part of the lens is for distance vision, while the bottom part is for near vision.
      3. Trifocal Lenses: These lenses have three different prescriptions in one lens, usually separated by visible lines. The top part of the lens is for distance vision, the middle part is for intermediate vision, and the bottom part is for near vision.
      4. Progressive Lenses: These lenses have a gradual change in prescription from the top of the lens to the bottom, allowing for clear vision at all distances without visible lines.
      5. High-Index Lenses: These lenses are made from a thinner and lighter material than traditional lenses, which can make them more comfortable to wear and reduce the appearance of thick lenses.
      6. Photochromic Lenses: These lenses darken when exposed to UV light, making them ideal for use as sunglasses.
      7. Polarized Lenses: These lenses reduce glare and improve visibility in bright conditions, making them ideal for outdoor activities such as driving or water sports.
      8. Anti-Reflective Coating: This coating is applied to the lens to reduce glare and reflections, which can improve vision and reduce eye strain.
      9. Blue Light Blocking Lenses: These lenses are designed to block blue light from digital devices, which can reduce eye strain and improve sleep quality.

      Blue light blocking lenses are designed to reduce the amount of blue light that enters your eyes. Blue light is a type of light that is emitted by digital screens such as smartphones, computers, tablets, and TVs, as well as by LED and fluorescent lighting. Exposure to blue light can cause eye strain, headaches, and disrupt sleep patterns.

      Blue light blocking lenses work by filtering out blue light, either through a coating applied to the lens or by using a specialized material in the lens itself. This helps to reduce the amount of blue light that enters your eyes and can help to alleviate the symptoms of digital eye strain.

      There are several different types of blue light blocking lenses available, including those that are designed for everyday use and those that are specifically designed for computer use. Some blue light blocking lenses are also available with a prescription, so you can get the benefits of blue light protection while still correcting your vision.

      If you spend a lot of time in front of digital screens or under artificial lighting, blue light blocking lenses may be a good option for you. They can help to reduce eye strain and improve your overall visual comfort.
