What You Need to Know About Medical Glasses

Eyeglasses are the most common form of vision correction, even though contact lenses and laser corrective procedures are becoming more popular. Glasses are a great option for anyone with an eye condition that requires specialized lenses, and there are many different frames styles and options to choose from. Glasses can also be upgraded with convenient features, like blue-light protection or lens tint.

Eye care professionals take multiple measurements throughout an eye exam, and these measurements are used to create a custom pair of glasses for each patient. These glasses are then sent to an optical lab, where they’re crafted specifically for your prescription and eyeglass needs. Glasses can cost from $200 to $300+ without insurance depending on your prescription and frame choice. Prices increase with additional bells and whistles like higher-quality lenses, specialty coatings or designer brands.

When نظارات غوتشي purchase glasses, you’ll likely be given a copy of your prescription with all the information needed to create them. This prescription is called a “prescription slip.” Understanding this information can help you select the right frames for your vision needs, and it can also save you money when buying glasses online.

Generally speaking, your glasses prescription will list two numbers, the Sphere (SPH) and Cyl (CYL). The first number will indicate how farsighted or nearsighted you are. The second number will tell your eye care professional how much astigmatism you have. Astigmatism is a condition that causes the cornea to be shaped more like a boiled egg than a flat pancake. The CYL value on your prescription indicates the power necessary to correct this irregularity.

The refraction index of your lenses is another important piece of information to know. The lower the refraction index, the thicker your lenses will be. The higher the refraction index, the thinner your lenses will be. Modern lenses are often made with high refractive indices that make them lighter and thinner than older glasses.

If you’re over 40 and experiencing presbyopia, your prescription will probably contain a “bifocal” or “trifocal” designation. These are lenses that have two or more prescriptions in them to correct multiple vision problems at once. Typically, bifocal and trifocal lenses have an upper portion that helps with distance vision while the lower half is for close-up reading. In some cases, you may need a monovision lens, which will just have one prescription for both distance and near vision.

Medical glasses can be helpful for many people, especially healthcare workers who need to protect their eyes from bodily fluids or debris. The most commonly prescribed medical eyewear includes safety glasses that offer protection against certain levels of non-ionizing radiation, which can be harmful to the eyes.
