You can graduate both sunglasses and prescription glasses, with the exception of some models for which lens graduation may not be possible. How can I proceed with the graduation of glasses? Select the desired product and after choosing colour and size, click on the "ADD PRESCRIPTION" button. Indicate how you will use the glasses (whether distance, near or without prescription). Upload the prescription or send it later. Choose the lens type (sun, clear, photochromic), treatment, colour and intensity. Click on "Add to cart" to complete your order. Please note that frames purchased in combination with prescription lenses are considered customised products and therefore cannot be refunded.
<p>To be able to graduate your lenses, we need the updated prescription written by your eye doctor, with values for the right and left eye. It is important that your values are no older than 2 years.<br /> <br /> If you experience any difficulties, you can upload your prescription during the process and our opticians will process it on your behalf.</p> <p><strong>How to read the eye prescription:</strong></p> <p>In addition to RE (right eye) and LE (left eye), here are other common abbreviations that may be helpful in understanding your prescription:</p> <p><span style="text-decoration: underline;">Sphere (S/SPH)</span>: The sphere indicates lens strength. In front of the value is a plus (+) symbol if you are presbyopic and a minus (-) sign if you are nearsighted. Pay attention to the symbol when placing your order. If no symbol is present, it usually indicates a plus (+) value.</p> <p><span style="text-decoration: underline;">Interpupillary distance (PD): </span>the interpupillary distance is the respective position between the center of the pupil and the center of the bridge of the nose. This tends to be different for both the right and left eye and is usually between 25 and 38 mm. This value is often denoted as a single number between 50 and 76 mm. In this case it denotes half of this value for each respective eye. For example, if you have a value of 60 mm, this would denote a distance of 30 mm for the right and left eye, respectively.</p> <p><span style="text-decoration: underline;">Cylinder (ZYL/ CYL):</span> Relevant only to those with corneal irregularities: the cylinder indicates the height of the corneal curvature.</p> <p><span style="text-decoration: underline;">Axis (A/ACH)</span>: Relevant only to those with corneal irregularities: the axis is expressed in degrees and defines the alignment of the cylinders needed to correct corneal irregularities. You will need it for your lenses to be properly aligned. The axis is always between 0° and 180°.</p> <p><span style="text-decoration: underline;">Addition (ADD)</span>: Relevant only for varifocal spectacles: addition (ADD) denotes lens strength, in addition to distance correction. This is important for those who also need help when seeing things up close, such as when reading. This value is always positive and is often the same in both eyes.</p>
The interpupillary or pupillary distance (abbreviated as DP) is the distance that passes between the two pupils of the eyes and is measured in millimeters. It is a measurement that does not change over the course of an adult's lifetime: generally in a large person the average distance is 62 millimeters, but can vary between 54 and 74 millimeters; while for children it ranges between 43 and 53 millimeters. Can I graduate lenses without indicating the interpupillary distance? No, you cannot: in order to complete the preparation of your prescription lenses, we need to receive a copy of your prescription and to know the value of your interpupillary distance. Measuring interpupillary distance at home Our advice is always to consult specialists, but if you would like to satisfy your curiosity and know your interpupillary distance, you can also do it at home with very few items. All you need is a mirror and a ruler; if you want you can get a family member or friend to help you. Those who have very dark eyes may have more difficulty identifying the pupil, therefore, you need a room with good lighting. Two different methods can be used to measure interpupillary distance at home: The first requires the person to wear eyeglasses well on the nasal septum and alone with the help of a mirror mark with a marker directly on the lens the point representing the center of the pupil. On the other hand, if the cooperation of a person is needed, it is good not to look straight ahead, but at the ear of the person in front of you. For example, if we are taking the measurement of the right eye one should look at the opposite ear of the person who is taking the measurement. The operation should also be repeated for the left eye in the same way. At the end, the two dots made on the lens will be measured with a ruler and this will be the interpupillary distance. At the end of the measurement, we recommend cleaning the glasses well. The second, on the other hand, does not involve the use of glasses, but requires the person to stand about 20 cm away from the mirror in a well-lit room. In this case, a ruler is needed to be held horizontally at eyebrow height. With a straight head, close the right eye and align the zero of the ruler with the center of the left pupil. Then open the right eye and see the measurement considering the center of the right pupil. Note the recorded DP measurement, and then repeat the measurement one or more times by reversing the starting eye. If the measurement is taken by another person, be careful to look over the head of the friend or family member.
To avoid ordering lenses that are too thick, we recommend carefully selecting the lens thickness when customising your glasses. In general, medium-high or high prescriptions are not recommended with low-index lenses, as they may be thicker and less lightweight. During the purchase process, you can choose from different lens types, such as Standard, Extra thin and light or Super thin and light, viewing the main features, lens index and updated cost for each option. Higher-index lenses are designed to offer a better aesthetic result, greater lightness and a more comfortable fit, especially for stronger prescriptions.
To save your prescriptions for future purchases, you need to have a personal Amevista account. If you are registered, you can access your Reserved Area, go to the “Profiles and Prescriptions” section and enter as many prescriptions as you wish, assigning each one a name, for example “Mine”, “Mum” or “Dad”. Alternatively, you can start the prescription lens process directly from the product page: after entering the prescription, you can save it with the name you prefer and find it again in your Reserved Area for future purchases. If you do not have an account or do not log in, it will not be possible to save prescriptions for future orders. How can I place an order using the prescription details saved in my account? Log in, select the frame, start the prescription lens process and, when entering the prescription, you will be able to upload one of those saved in your Reserved Area.
At the moment, Amevista does not offer a separate lens sales service for frames you already own or have previously purchased.
Polarised lenses are among the most advanced visual solutions available: thanks to a special filter, they can eliminate light reflections, also known as glare, which can disrupt vision. The result is clearer and more defined vision in many everyday situations. Additionally, these lenses help reduce visual stress, contributing to the prevention of discomfort such as red eyes, visual fatigue, and headaches. Key benefits of polarised lenses include: Increased driving safety: On bright days, intense reflections or blurred images can impair visibility. Polarised lenses mitigate these effects, ensuring more comfortable vision and greater visual readiness while driving. Reduced eye strain: Prolonged exposure to intense light often leads to squinting to see better, causing strain that can result in discomfort or migraines. Polarised lenses help prevent these issues, enhancing eye comfort. Ideal for water sports: Those engaging in water activities often choose polarised lenses, as they allow clearer vision beneath the surface by reducing light reflection on the water. More vivid colours and sharper images: Many users report a significant improvement in detail and colour perception, with clearer and more realistic vision in any environment.
Photochromic lenses are lenses that automatically adapt to light: they remain clear indoors and darken outdoors, offering visual comfort and protection against UVA and UVB rays. “Photochromic” therefore refers to the general lens category, while Transitions is the leading photochromic lens brand produced by Essilor. Among the Transitions solutions, Gen S offers very fast light adaptation, 100% UVA and UVB protection, blue-violet light protection up to 26% indoors and up to 86% outdoors, darkening in around 25 seconds, returning to clear in around 90 seconds and 8 available colours. Transitions XTRActive is designed for those who want extra protection from intense light: it also activates in the car, maintains a slight tint indoors, offers 100% UVA and UVB protection, blue-violet light protection up to 45% indoors and up to 86% outdoors, darkening in around 35 seconds, returning to clear in less than 2 minutes and 3 available colours.
Full-frame in acetate or plastic: To remove the original lenses, identify the most flexible or straight section of the frame to start from. Firmly press on the inside of the lens (the concave side) to pop it out. In some cases, gently warming the frame can make the plastic more pliable and facilitate removal. A good method is to grip the frame securely and push it away from the lens. To insert the new lenses, follow the reverse process: start from the more curved side (usually near the temple) and carefully work along the edge of the frame, finishing the insertion on the nose side. With the right amount of pressure, the lens will snap into place. Fully metal frame: These frames usually have a small screw on the back near the temples. To install new lenses, slightly loosen this screw without removing it completely — this will widen the frame and make lens placement easier. Carefully align the replacement lenses, then retighten the screw to secure them. Semi-rimless frame: To remove the lenses, gently grasp them and push towards the temple side, then lift slightly to release. To insert the new lenses, begin by placing the thinnest part of the lens (usually on the temple side) into the frame, then slide the rest of the lens upward from the bottom to complete the installation.
At the moment, Amevista does not provide single-piece lenses that cover both eyes in one solution. Our lenses are designed exclusively for frames that accommodate two separate lenses. While we hope to offer this option in the future, the only currently available alternative is to contact the mask manufacturer directly for compatible solutions.
No, currently only lenses on sunglasses and prescription frames can be graduated online.
