## Buying guides
- [Clip-On vs Fit-Over vs Prescription Sunglasses](https://eyeweartested.com/guides/clip-on-vs-fit-over-vs-prescription-sunglasses): Clip-ons attach to a compatible glasses frame, fit-overs are worn over the glasses you already use, and prescription sunglasses put corrective lenses in a separate sunwear frame. The practical choice depends on how well the option fits your current glasses, how you want to switch pairs and which UV protection is stated for the exact lenses. Check dimensions and product specifications before ordering.
- [Daily vs Monthly Contact Lenses: Cost, Comfort and Care](https://eyeweartested.com/guides/daily-vs-monthly-contact-lenses): Daily disposable lenses are worn once and thrown away, so there is no cleaning, lower infection risk and fresh comfort every day, but they cost more per year. Two-week and monthly lenses are cleaned and stored each night in solution, which lowers lens cost but adds care routines and solution costs. Dailies suit occasional wearers, allergy sufferers and travelers; monthlies suit daily wearers who are diligent about care. Your eye care provider must fit and prescribe them.
- [How to Buy Glasses Online: Prescription, PD and Fit Checks](https://eyeweartested.com/guides/how-to-buy-glasses-online): Before ordering glasses online, get a current eyeglass prescription and the pupillary-distance measurement the retailer requests. Compare the new frame with a pair that already fits, enter each prescription field carefully and review lens options, delivery timing, adjustment help and return terms. If the prescription or fit is complex, or the retailer cannot explain its fitting process, an in-person optician can help you avoid a poorly matched order.
- [How to Read Your Glasses Prescription: OD, OS, SPH, CYL and AXIS](https://eyeweartested.com/guides/how-to-read-your-glasses-prescription): OD is your right eye and OS your left. SPH (sphere) is the main lens power: minus numbers correct nearsightedness, plus numbers correct farsightedness. CYL and AXIS correct astigmatism: CYL is the strength and AXIS is the angle from 1 to 180. ADD is extra magnifying power for reading, used in progressive and bifocal lenses. To order glasses online you also need your PD, the distance between your pupils in millimeters.
- [Eyeglass Lens Coatings Explained: Anti-Glare, Blue Light and More](https://eyeweartested.com/guides/lens-coatings-explained): Anti-reflective (anti-glare) coating is the most worthwhile upgrade: it cuts reflections, helps night driving and makes lenses look clearer. Scratch-resistant coating is standard on most plastic lenses, and polycarbonate and high-index lenses block UV. Photochromic lenses darken outdoors. Blue light filtering is optional: major eye care organizations do not recommend it for eye health, though some people find it more comfortable.
- [OTC vs Prescription Reading Glasses: How to Choose](https://eyeweartested.com/guides/otc-vs-prescription-reading-glasses): Over-the-counter readers use the same lens power in both eyes and are intended for near vision. Prescription readers can account for a different correction in each eye, astigmatism and lens-centering measurements. If you see clearly at distance and have no other vision correction needs, ready-made readers may be an option, but an eye-care professional can determine the right power and check your eye health.
- [Photochromic vs Polarized Sunglasses: What Each Feature Does](https://eyeweartested.com/guides/photochromic-vs-polarized-lenses): Photochromic lenses change tint as light conditions change, while polarization reduces reflected glare from surfaces such as roads and water. Neither label tells you the lens's UV protection, and one feature does not automatically include the other. Some lens products combine them, so compare the exact lens specification and the light conditions where you will use it.
- [Polarized vs UV Sunglasses: What Protects Your Eyes](https://eyeweartested.com/guides/polarized-vs-uv-sunglasses): UV protection and polarization do different jobs. UV protection blocks harmful ultraviolet light and is what protects your eyes; look for 100% UV protection or UV400. Polarization cuts glare reflected off water, roads and snow, which makes sunglasses more comfortable but doesn't add UV protection on its own. Lens darkness is separate again: dark lenses without UV protection can be worse than none.
- [Prescription Sunglasses: What to Check Before Buying](https://eyeweartested.com/guides/prescription-sunglasses-buying-guide): For prescription sunglasses, confirm the prescription and measurements the seller needs, then check UV protection separately from tint and polarization. Dark lenses do not prove UV protection, and polarized lenses address reflected glare rather than serving as a UV label. Choose a tint and frame for the light and activity you face, and ask an optician whether the frame shape and your prescription are compatible before ordering.
- [Progressive vs Bifocal Lenses: Which Should You Choose?](https://eyeweartested.com/guides/progressive-vs-bifocal-lenses): Progressive lenses change power smoothly from distance at the top to reading at the bottom, with no visible line, so they look like regular glasses and also cover middle distances like a computer screen. Bifocals have two zones separated by a visible line: distance on top and reading below, with a wider reading area but no intermediate zone. Progressives suit most people but take a week or two to adjust to; single-vision readers are simplest if you only need help up close.
- [Toric vs Spherical Contact Lenses: What Changes](https://eyeweartested.com/guides/toric-vs-spherical-contact-lenses): Spherical contact lenses use a uniform optical power, while toric lenses include different powers in different directions to correct astigmatism. Toric lenses need to stay in a specific orientation, and their prescription includes additional details such as cylinder and axis. The lens design and replacement schedule are separate choices, so use the exact product and parameters on your current contact lens prescription.
- [Blue Light Glasses: What the Evidence Says](https://eyeweartested.com/guides/blue-light-glasses-evidence): Blue-light glasses filter some wavelengths, but the American Academy of Ophthalmology does not recommend special eyewear for routine computer use because current evidence does not show that screen blue light damages the eyes. Digital eye strain is more often tied to focusing demands, reduced blinking, glare and posture. Adjust the screen setup, take breaks and ask an eye care professional about persistent symptoms or a prescription need.
- [Computer Glasses Guide: Prescription, Distance and Fit](https://eyeweartested.com/guides/computer-glasses-guide): Computer glasses are useful when your current prescription is not comfortable at your usual screen distance and an eye care professional confirms a work-specific correction. They are not the same as blue-light glasses, which filter some visible wavelengths but do not correct focus. Tell your provider how far away the screen sits, how many monitors you use and whether you also need to see across the room.
- [Contact Lens Care: Cleaning, Storage and Safe Habits](https://eyeweartested.com/guides/contact-lens-care-guide): Contact lens care depends on the lens type and care system. Follow the instructions from your eye-care provider and the solution maker, use fresh solution whenever you remove reusable lenses, and never top off old solution. Keep lenses and their case away from water; peroxide systems need their special case and the full label-directed soak time. Daily disposables and rigid gas-permeable lenses have different routines, so do not substitute one care method for another.
- [Contact Lens Prescription: Fields to Check Before Ordering](https://eyeweartested.com/guides/contact-lens-prescription-guide): A contact lens prescription is specific to the prescribed lens, not just the power in your glasses prescription. Before ordering, match the manufacturer or brand, power, base curve, diameter when listed, and the prescription’s expiration date. Expiration rules depend on state law, with a federal one-year default where a state has not set a minimum.
- [Traveling With Contact Lenses: A Packing and Care Guide](https://eyeweartested.com/guides/contact-lens-travel-guide): Pack enough lenses and care supplies for the whole trip, plus backup glasses and a clean case. Keep your normal wear and replacement schedule, wash and dry your hands before handling lenses, and keep lenses and cases away from water. Bring the solution intended for your lenses. For U.S. flights, check TSA's current solution entry because larger bottles require special screening and some products can be refused.
- [Eyeglass Frame Materials: How to Choose](https://eyeweartested.com/guides/eyeglass-frame-materials-guide): Choose a frame by how it fits your face and daily routine, then use its material as a tie-breaker. Acetate and other plastics offer color choices and are straightforward for an optician to adjust, while titanium is light, strong and resistant to corrosion. Metal alloys differ, so check the exact material and ask about nickel if you have a sensitivity. A mixed frame can combine looks or features, but its fit and serviceability still matter most.
- [Glasses Frame Size Guide: What 52-18-140 Means](https://eyeweartested.com/guides/glasses-frame-size-guide): Glasses frames are sized with three numbers, usually printed inside the temple arm: lens width, bridge width and temple length in millimeters. In 52-18-140, the lenses are 52 mm wide, the bridge is 18 mm and the arms are 140 mm long. The easiest way to find your size is to copy the numbers from a pair that already fits. Total frame width should roughly match the width of your face.
- [High-Index Lenses: When They Can Make Glasses Thinner](https://eyeweartested.com/guides/high-index-lens-buying-guide): A higher-index lens material bends light more efficiently, so the same prescription can use less material and produce a thinner lens. The finished result also depends on your prescription, frame size and shape, and lens design. Ask an optician to compare options using the frame you plan to wear.
- [How to Clean Glasses Without Scratching the Lenses](https://eyeweartested.com/guides/how-to-clean-glasses): Rinse your glasses under lukewarm water, rub a drop of lotion-free dish soap over the lenses and frame with clean fingers, rinse, and dry with a clean microfiber cloth. Use lens spray and a microfiber cloth on the go. Avoid paper towels, tissues, clothing, saliva, household glass cleaners and hot water, which scratch lenses or damage coatings. Store glasses in a hard case, lenses up when set down.
- [Kids’ Eyeglasses Buying Guide: Fit, Lenses and Durability](https://eyeweartested.com/guides/kids-eyeglasses-buying-guide): Start with the child’s prescription and a frame that sits comfortably with each eye centered behind its lens. A pediatric eye care professional or optician can help match frame size, bridge shape, temple length and lens options to the child’s face and prescription. Let the child help choose a style they will wear, then confirm the fit after adjustment and plan for repairs or a backup pair if needed.
- [Prescription Safety Glasses: Match Protection to the Hazard](https://eyeweartested.com/guides/prescription-safety-glasses-guide): Choose prescription safety eyewear for the hazard, not just your vision prescription. OSHA requires workplace eye protection suited to the hazard and side protection when flying objects are a risk; prescription lenses must be part of the protective eyewear or worn underneath without shifting it. Check the workplace hazard assessment and the requirements for the task before buying.
- [Sport Sunglasses: How to Choose Coverage, Fit and Lenses](https://eyeweartested.com/guides/sport-sunglasses-buying-guide): Choose sport sunglasses around the activity first: they should stay put, cover the sides of your eyes and clearly state their UV protection. Then compare lens tint and polarization for the light and glare you face, frame coverage with a helmet, and whether the model is available in your prescription. For impact risks, look for eyewear specifically identified for the sport and use rather than assuming a dark lens or a fashion frame is protective.
- [How to Choose Sunglasses for Your Face Shape](https://eyeweartested.com/guides/sunglasses-for-your-face-shape): A simple rule: contrast your face shape with your frames. Round faces suit angular or rectangular sunglasses, square faces suit round or aviator styles, heart-shaped faces suit bottom-heavy or aviator frames, and oval faces suit almost anything. Fit matters more than any rule: the frame should be about as wide as your face, sit level and not touch your cheeks.
