10 Tips to Take Care of Your Visual Health
Sight is a sense that we all value highly, so it is very important to enjoy good visual health. But we are often not as aware as we should be about caring for our eyes. If you want to know what you can do about it, here are ten tips to help you take care of your visual health best. Recommendations to take care of visual health Prevention and Attention to Discomfort Even if there are no noticeable symptoms, an annual check-up is always advisable to ensure everything is fine. Even before you feel discomfort, redness, tiredness, etc. Diet is Important for Visual Health. Starting from the essentials, a diet rich in vitamins and minerals can help you maintain good visual health. Although carrots are the most famous, green foods such as broccoli, zucchini, and peas are the richest in lutein and zeaxanthin, essential nutrients for eye health. It is also good to consume foods rich in omega-3 fatty acids, and green tea is one of the most suitable drinks to help your eyes against macular degeneration and cataracts. Care and Maintenance of Glasses If you wear Prescription Lenses, paying attention to the condition of the lenses and frame is very important. Even if they are consistent in design, if the frame is loose and doesn't fit properly, it can cause strain on your eyes. The same thing happens with the crystals if they are not in good condition. To clean them, it is best to do it appropriately, and with optical products, avoid homemade cleaning methods as much as possible, which can end up ruining the lenses, and never clean them dry to prevent dust particles. They end up scratching the lens. Extreme Hygiene When Wearing Contact Lenses The eyes are very delicate organs. Therefore, contact lenses must be cared for and cleaned extremely neatly. Always follow the steps indicated by your optician, clean them with an appropriate product, and try to give your eyes a break for a few hours a day and at least one day a week. Never bathe with contact lenses or wet them with water, and avoid sleeping with them (if they are not intended for this purpose). Sunglasses are Essential Exposure to ultraviolet (UV) rays can cause serious visual disorders. You must wear the Polarized Glasses when exposed to sunlight, not only during the summer but throughout the year. Remember that they are also essential if you are going to practice outdoor sports and when you are going to drive. Above all, buy them at Manha’s store to ensure that they have adequate protection so as not to put your visual health at risk. Watch Distance and Light when Looking at Screens. The use of computers at work and, at the same time, the use of mobile devices such as phones and tablets at any time of the day is becoming more common. To avoid eye strain and damage to your eyes, it is advisable to keep a wide distance from screens. For computers, it would be advisable to be at least 50 cm from the screen. It is also advisable not to use any of these devices in the dark since the screen's light and the environment's darkness can cause eye fatigue and graduation problems. Don't Let Your Eyes Dry. Eyes, like skin, need moisture. This is more critical when your eyes are sensitive, so you must try to moisturize them. If you suffer from dry eyes, it is good to have artificial tears on hand to help your eyes maintain the necessary moisture. Protect Your Eyes Even During Everyday Actions. The eyes are more sensitive than one assumes, and even the most innocent actions can damage them. While certain jobs require protective glasses, other tasks, such as cleaning, gardening, or applying makeup, can cause impurities to enter the eyes and, in extreme cases, cause infections. The Older You are, the More Prevention As the years go by, the eyes are more prone to suffering from other visual diseases, so check-ups become increasingly important. This increases when it comes to people with a tendency to suffer from diseases such as diabetes, cholesterol, or hypertension. The Eyes Need to Rest. Even if you are not working, your eyes are constantly working. You must take breaks, whether in front of a computer screen, reading a book, or straining your eyes by manipulating small objects. Every time you feel tired (or every twenty minutes, for example), try looking at the horizon without focusing on anything or closing your eyes without squeezing your eyelids so they can rest a little. These small, quick, and simple actions will relax you, and your eyes will thank you.

Learn Everything About Virtual Reality Headset
Virtual reality, once specific to cinema or simulators reserved for a few technophiles, is beginning to invade our daily lives, and becoming more popular. Today, many applications and video games allow total immersion in the heart of the action thanks to virtual reality headsets, which provide an exceptional feeling. Find out what virtual reality is and what equipment is necessary to choose a quality VR headset. What is virtual reality? It is a computer technology that simulates a user's physical presence in an environment artificially generated by software. The user can also interact with this fictional environment. Virtual reality artificially reproduces a sensory experience, which can include sight, touch, hearing and possibly smell. It was originally developed to reproduce complex situations and offer simulations or training. We can think of flight simulators that allow airline pilots to practice in risky situations. With the miniaturization of display technologies and the progress of computing, virtual reality has reached the private sphere. Where once it was necessary to build an entire room to simulate an environment (aeroplane cockpit, for example), today, everyone can put on a virtual reality headset and find themselves immersed in the heart of the Amazon jungle, in a spaceship, or at the edge of a ravine! In just a few years, virtual reality headsets have developed prodigiously. Game and software publishers have followed suit and today provide many products that allow total user immersion. Most of the market is focused on VR gaming headsets, and more "serious" applications are still rare. A virtual reality headset: How it works The operation of a VR headset is quite simple, even if it implements complex technologies. In virtual reality, users do not look at a flat screen in front of them but through a headset encompassing the entire field of vision. This headset projects a small image for each eye, and the brain combines them to transform them into 3D vision. As the headset's lenses amplify the image, players see images that fill their field of vision. These images move with the movements of the person's head since the helmet is fixed on it. The software then adapts the image according to the position of the head and the angle of view. Just as if the user were turning their head in the virtual world, allowing them to look towards the sky or behind them for example. This effect gives a deep feeling of immersion and ensures that you quickly forget the screen fixed in front of your eyes. To give a feeling of reality and fluidity in the world we are immersed in, VR headsets must achieve technical feats regarding display. Unlike television, which has a display frequency of 30 frames per second, virtual reality displays moving images at 90 frames per second or even sometimes 120. The higher the display speed, the more immersed the player will feel in the real world. How to choose a virtual reality headset? Equipment Used: There are still very few completely universal virtual reality headsets. Your choice will, therefore, depend on the type of hardware on which you wish to use it. You can find virtual reality headsets that can be used with PCs with game consoles (some are even associated only with one type of console) or smartphones. Some products can work on multiple platforms simultaneously, but they are rare. Today's most efficient VR headsets are those found in PC or console equipment. Then, in each range, we can distinguish 4 essential criteria to consider when choosing a VR headset: Display Quality: Display quality is essential for a successful virtual reality experience. It will particularly depend on the type of screen panel that is used for the headset and, of course, also on its definition. Today, the best products have 4K UHD or OLED screens. The latter are remarkable for their depth of black and nocturnal atmospheres. They also have the advantage of a very low retention time: the images persist little on the screen, thus increasing the sensation of real vision. The Reactivity: A virtual reality headset must detect all of the user's movements as quickly and faithfully as possible. This is important to display an image with minimal lag with movements. If this gap is too great, it creates a feeling of unreality and discomfort. For some players, this can go as far as feeling unwell. Today, many high-end headsets have a latency of less than 20 ms. It should be noted that the latency not to be exceeded is around 40 ms. The display frequency is also important for the responsiveness of the headset. Today, the best products are at 90 or even 120 Hz. But there are decent ones at 60 Hz. Products below this value offer less immersion and should be avoided. Comfort: During a gaming session, the headset must be forgotten. If your VR headset is uncomfortable, you will want to take it off after a while. The first important parameter is weight. Most helmets today exceed 200 grams, and some exceed 400 grams. Beyond this limit, the weight will be too heavy over time. You also need good support foam on the face so the helmet can adapt to different body shapes and visions (wearing glasses, adjusting the sharpness, etc.). Finally, make sure that the straps are adjustable to adapt your VR headset to the size of your face. The Accessories: Some helmets are sold "naked" but other models offer accessories to increase immersion. We find some delivered with motion controllers that allow more than a classic VR experience in a seated position. The device then allows immersion of the whole body, thanks to the possibility of moving over several meters (infrared sensors are installed in the room) and movement recognition. Sound accessories are also important. Some models include audio integration with the VR headset; others do not let users equip themselves with their system (or do without a sound headset). We recommend the most integrated systems possible because these are the ones that allow ultimate and effective immersion. Manha- M1 Virtual Reality Headset: With its integrated headphones and microphones, wide viewing angle, and 90 frames per second, this virtual reality headset from Manha ensures complete immersion in the game. The headset's lens can be flipped up for a quick return to reality. Ergonomic, it has an adjustable headband, and the shape of its headphones is designed to fit that of the ears.

What are Polarized Glasses & their Benefits?
Our sight is continually exposed to the sun's rays directly and indirectly. Blocking sunlight that hits the eyes, such as that which comes from the reflection of the sea, snow, road, or asphalt, it’s very important to maintain our visual health. An effective option is to use polarized glasses to enjoy these types of activities without taking risks. Thus, to practice certain sports or drive it is necessary to have sunglasses with appropriate lenses. These are polarized glasses, which act as a filter for our vision against those annoying and harmful reflections. At Manha Eyewear, we are clear that each activity requires specific glasses, with different treatments for the lenses. Polarized glasses are especially suitable for outdoor activities, such as water or snow sports, or driving. Do you still have doubts when choosing between normal or polarized sunglasses? What Advantages Do Polarized Glasses Have? Polarized glasses have the advantage of filtering reflected light and reducing glare on surfaces such as water, snow, or the road, making them especially useful for outdoor activities, such as fishing, skiing, or driving. Polarized glasses can also improve the clarity and contrast of vision, which can be beneficial in many different situations. What are Better Polarized Glasses or those with a UV filter? UV filter glasses and polarized glasses are not mutually exclusive, and in fact, glasses should ideally have both characteristics. UV filters protect your eyes from the sun's ultraviolet rays, which can be harmful in the long term, while polarized glasses reduce glare and improve clarity of vision. Therefore, it is advisable to choose glasses that have both UV filter and polarization. What is Better Polarized or Normal Sunglasses? This depends on the situation and the user's needs. Regular sunglasses can protect against UV rays and reduce light intensity, which can be useful in many different situations, such as walking around the city or doing outdoor sports on cloudy days. However, polarized sunglasses are more effective at reducing glare and improving clarity of vision on reflective surfaces. Therefore, if you plan to carry out activities in environments with reflective surfaces, polarized sunglasses may be a better option. How do you know if your Sunglasses are Polarized? There are several ways to check if sunglasses are polarized or not: Looking through an LCD screen: If you place the polarized sunglasses in front of an LCD screen (such as a TV, laptop, or cell phone) and rotate the glasses while looking at the screen, you should see the screen go dark or dark. It disappears completely at certain angles. This occurs because polarized glasses block polarized light at certain angles. Looking through water reflection: If you are near a body of water and look through sunglasses while turning your head, you should see a reduction in glare and glare from the water compared to when you are not wearing polarized sunglasses. Looking through two pairs of polarized glasses: If you place two pairs of polarized glasses on top of each other and rotate one of them, you should see the light dim or disappear at certain angles. Look for a polarization logo: Many polarized glasses have a logo indicating that they are polarized, so you can look at the temples or lens of the glasses to see if there is a logo that indicates polarization. It is important to keep in mind that not all sunglasses have polarization and that some verification methods may not be 100% accurate, so if you have doubts about whether your glasses are polarized, you can consult with our opticians and optometrists. Benefits of Polarized Glasses: Here are some of the benefits of wearing polarized sunglasses: They improve contrast in intense or diffuse light (they do not darken as much as normal sunglasses when we go from a very bright area to a darker one). They enrich the perception of colours. They minimize glare from the reflection of the sun's rays on certain objects or surfaces. They increase the high definition of details. They offer excellent sun protection. They protect 100% from UV rays.
