Key Points Lens thickness depends on your prescription, lens material, and frame size. High-index lenses can help reduce lens thickness. Some high prescriptions can be combined with progressive or photochromic lenses. High astigmatism and prism correction may require additional review. If you’re unsure about your options, you can contact MiGAFAS before ordering. Smaller full-rim acetate frames, particularly those with a lens width under 50 mm, can be a good starting point for high prescriptions.   If you have a high prescription, you may wonder whether your lenses will be too thick, which frames will work best, or whether you can choose progressive or photochromic lenses. The right combination of frames and lenses can help you find glasses that fit your prescription and your lifestyle. Here’s what to consider before ordering. What Is Considered a High Prescription? A high prescription generally refers to a stronger lens power needed to correct your vision. Your prescription may also include astigmatism, reading power, or prism correction, which can affect your lens options. Nearsightedness, farsightedness, and astigmatism are different types of refractive errors. Learn more from the National Eye Institute . Why Are High Prescription Lenses Thicker? Stronger prescriptions can require thicker lenses. Nearsighted lenses are generally thicker at the edges, while farsighted lenses are generally thicker in the center. Thickness also depends on your frame size, lens material, and prescription details . Choosing the right combination can help create a slimmer, more comfortable pair. What Are the Best Lenses for High Prescriptions? High-index lenses are a popular option for people who want thinner-looking glasses. They bend light more efficiently than some standard lens materials, so they can often be made thinner for the same prescription. You may see options such as 1.61, 1.67, or 1.74 . A higher index may help reduce thickness, but the best choice depends on your prescription, frame, and available lens options. Remember, a higher index isn’t the only consideration. A well-fitting frame can also make a difference in how your finished glasses look and feel. Not sure which lenses to choose? Share your prescription and preferred frame with our team, and we can help you check the available options. Get Help With Your Prescription Can You Get Progressive or Photochromic Lenses With a High Prescription? A high prescription doesn’t automatically mean you have to give up these lens features. Some prescriptions can be combined with progressive or photochromic lenses, depending on the available lens materials and manufacturing range. Progressive Lenses Progressive lenses may be an option if you need help seeing at different distances and your prescription includes an ADD value. The frame needs enough height for the lens design, and accurate fitting measurements are important. As ZEISS explains , the reading area needs sufficient space within the frame. If your prescription is strong or includes prism, we recommend checking your options before ordering. An eye care professional can also help with measurements and frame fitting. Explore Progressive Lenses Photochromic Lenses Photochromic lenses adjust their tint in response to light and may be available for some high prescriptions. The available colors, lens materials, and prescription ranges can vary. Keep in mind that most photochromic lenses may not darken as much inside a car because the windshield blocks much of the UV light that activates them. Learn more about how photochromic lenses work . Explore Photochromic Lenses Want progressive and photochromic lenses in one pair? Contact us with your prescription and preferred frame so we can check whether the combination is available. What Are the Best Frames for High Prescription Glasses? Choosing the right frame is just as important as choosing the right lenses. For stronger prescriptions, a well-selected frame can help reduce lens thickness, improve comfort, and create a more balanced look. Here are five tips to help you choose: 1. Choose Smaller Frames (Under 50 mm Lens Width) For high prescriptions, especially strong nearsighted prescriptions, we recommend considering frames with a lens width (A measurement) of less than 50 mm , such as 47–49 mm, when the fit allows. Smaller lenses can help reduce visible edge thickness and overall lens weight. Try to avoid unnecessarily oversized frames, which may make thick lenses more noticeable. 2. Look for Full-Rim Frames Full-rim frames surround the entire lens, helping conceal thicker edges and provide support. They are often a better choice for high prescriptions than rimless or semi-rimless designs. 3. Consider Acetate Frames Acetate frames are an excellent option for stronger prescriptions. Their more substantial rims can help hide lens edges, creating a cleaner and more balanced appearance. If you prefer thinner metal frames, check with our team to see whether your preferred style works with your prescription. 4. Try Round or Oval Shapes Round, oval, and softly rounded frames can be good choices for high prescriptions. Their compact shapes may help minimize visible lens thickness, particularly for strong nearsighted prescriptions. 5. Make Sure the Frame Fits Your Face A smaller frame isn't always the best fit for everyone. Your pupillary distance (PD), face shape, and lens requirements also matter. If you need progressive lenses, choose a frame with enough lens height to accommodate the different viewing zones. How to Check Your Frame Size You may see measurements like 48□20–145 on the inside of a frame: 48 mm: Lens width (A measurement) 20 mm: Bridge width 145 mm: Temple length For high prescriptions, start by checking the first number. A lens width below 50 mm is a useful starting point, but it's not a strict requirement. Not sure which frame to choose? Send us your prescription and preferred frame, and our team can help you check the available options. Can You Get Glasses for High Astigmatism or Prism?

For astigmatism , enter both the CYL and AXIS values exactly as they appear on your prescription. You can learn more about astigmatism from the National Eye Institute .
