If you have myopia (nearsightedness) and want to protect your eyes from harmful UV rays while outdoors, choosing the right prescription sunglasses is essential. In addition to offering vision correction, these sunglasses can provide the UV protection you need. In this article, we’ll guide you through how to select the perfect prescription sunglasses and introduce the benefits of photochromic sunglasses from Maat Optical for added comfort and eye protection. Understanding the Importance of UV Protection for Your Eyes Exposure to intense sunlight for extended periods can damage your eyes, leading to vision deterioration and eye diseases. UV rays, invisible light with wavelengths ranging from 10 to 400 nanometers (nm), are especially harmful. These rays are divided into three types based on wavelength: UVA (long-wave), UVB (medium-wave), and UVC (short-wave). UVA rays are known to cause cataracts and retinal diseases, while UVB rays can lead to eye cancer and corneal damage. UV exposure can lead to several eye conditions, such as photokeratitis, conjunctivitis, pterygium, and more. UVA rays are particularly harmful, as they can penetrate deep into the eye and cause issues like macular degeneration and retinal damage. This makes photochromic sunglasses, which adjust to changing light conditions and provide UV protection, a critical choice for individuals with myopia. Why Choose Prescription Sunglasses? Prescription sunglasses combine the corrective power for myopia with UV-blocking capabilities. They are made by adding a tint to prescription lenses through a special process. This allows you to protect your eyes from harmful UV rays while maintaining optimal vision. In the summer months, when sunlight can be intense, prescription sunglasses are especially important for shielding your eyes from UV rays, which can cause long-term damage. Maat Optical offers high-quality photochromic sunglasses that automatically adjust their tint based on sunlight exposure, providing both vision correction and sun protection. Things to Consider When Choosing Prescription Sunglasses: For high myopia users (over 800 degrees): It is not recommended to wear prescription sunglasses if you have extremely high myopia. These lenses are often thicker, and when combined with the larger frames of sunglasses, they can become heavy and uncomfortable to wear, making them less stylish and less practical. Opt for lenses with good impact resistance: Prescription sunglasses are often worn outdoors, during activities that could cause accidents. Therefore, selecting lenses that can withstand impact and are durable is essential to avoid breakage. How to Choose the Right Prescription Sunglasses for You If you love outdoor activities like hiking, cycling, or sports, prescription sunglasses are a must. The protection and comfort they provide in bright outdoor environments can make a huge difference, especially when participating in vigorous activities. Different Types of Prescription Sunglasses Lenses: Standard Lenses: Common choices include gray, brown, and green lenses. Typically, photochromic lenses are gray, but Maat Optical offers a wider range of color options (gray, brown, pink, purple, blue, green), making them look more stylish. These are widely used and effective in blocking out UV rays, while also offering good aesthetic appeal. Brown lenses, for example, look great with gold frames. Fashionable Lenses: These lenses are designed for trendsetters and come in various bright colors and stylish patterns. If you’re looking for something more unique and fashionable, this is a great option. These lenses are particularly popular among individuals who want to make a statement. Customization Considerations Frame Curvature: Choose lenses that are customized to fit the curvature of your chosen frame, whether it's metal or acetate. Pupillary Distance: Ensure that the lenses are correctly aligned with your eyes by selecting the appropriate semi-automatic or high-curvature mode for grinding based on your pupillary distance. Edge Thickness: After grinding the lenses, if the edges are too thick, a manual edge-thinning process can be applied to make them more aesthetically pleasing. Maat Optical’s Photochromic Sunglasses: A Perfect Solution Maat Optical’s photochromic sunglasses are the ideal choice for individuals with myopia who need both vision correction and sun protection. These lenses adjust their tint based on sunlight exposure, providing maximum UV protection in bright outdoor environments, while maintaining transparency indoors. They also help to reduce glare and protect your eyes from harmful UV rays that cause long-term damage. By choosing Maat Optical’s photochromic sunglasses, you can enjoy clear vision in all lighting conditions and ensure your eyes are well-protected from the sun’s harmful rays.

Outdoor Activities Aid Myopia Prevention in Adolescents Time spent outdoors is a key factor influencing the onset and progression of myopia. Numerous studies have shown that increased outdoor activity can significantly help prevent myopia or slow its progression. Evidence suggests that outdoor activities effectively slow refractive changes in both myopic and non-myopic children. Increasing outdoor activity time is central to myopia prevention strategies and a crucial component of myopia control plans. Research has identified several actions that help in myopia control, such as increasing brightness, reducing peripheral defocus, raising vitamin D levels, exposure to light closer to the natural spectrum, more physical activity, a well-regulated day-night rhythm, less near work, and higher spatial frequency. Outdoor activities enhance vitamin D levels and light intensity, boosting dopamine release and blood flow in the retina, which supports sustained blood flow in choroid and retinal tissues. The contrast between indoor and outdoor light intensity is notable, as outdoor sunlight can reach up to 100,000 to 200,000 lx, while indoor lighting is usually limited to less than 1,000 lx. Under strong outdoor sunlight, the pupils naturally constrict, increasing depth of field and slowing the progression of myopia while reducing the light entering the eyes, thereby protecting the retina. Potential Eye Damage from Outdoor Activities The primary risk factor for eye tissue and visual function damage during outdoor activities is ultraviolet (UV) radiation. UV rays are divided by wavelength into three types: UV-A (315-400nm), UV-B (290-315nm), and UV-C (100-290nm). As UV radiation passes through the atmosphere, UV-C and around 90% of UV-B rays are absorbed by the ozone layer. Therefore, the UV radiation reaching the Earth's surface mainly consists of UV-A and a small amount of UV-B. Exposure to UV radiation is a known risk factor for eyelid malignancies (basal cell carcinoma and squamous cell carcinoma), photokeratitis, climate-induced droplet keratopathy, pterygium, cataracts, macular degeneration, and other retinal conditions. Over time, the risk of these conditions increases. Factors that influence UV-induced eye damage include wavelength, light intensity, and exposure duration. Shorter-wavelength UV rays are more biologically active and are mainly absorbed by the cornea. The longer the wavelength, the more UV rays can penetrate the cornea to reach the lens and retina. Generally, the cornea absorbs UV rays below 300nm, while the lens absorbs UV rays below 400nm. Due to differences in lens coloration, children and adults absorb UV differently; light above 300nm can pass through a child's lens (peak at 380nm), while light above 400nm can pass through an adult's lens (peak at 575nm). This makes children and adolescents more vulnerable to UV damage. Higher light intensity poses a greater risk to eye health, reducing contrast sensitivity, visual comfort, and performance, and causing glare, headaches, and temporary vision impairment. Additionally, during outdoor activities, children and adolescents may face accidental injuries, such as falls or collisions, which could cause eye injuries like corneal abrasions or blunt trauma to the eyeball. To prevent accidental injuries, parents should ensure children wear appropriate protective gear, such as helmets and goggles, during outdoor activities. Myopia Prevention Alongside Protection from Light Damage For children and adolescents participating in outdoor activities to control myopia, it is essential to obtain adequate light exposure while avoiding potential harm from excessive light. Wearing high-quality sunglasses or photochromic lenses, such as those provided by Maat Optical, can effectively block UV rays, reduce glare interference with vision, and minimize irritation from environmental factors like wind and dust. Photochromic sunglasses are particularly beneficial, as they offer adaptable protection under varying light conditions. These lenses darken in bright sunlight, shielding the eyes from harmful UV rays, and become clear in low-light environments, providing a comfortable visual experience indoors or outdoors. This adaptability makes them ideal for children undergoing myopia control treatment with medium- to high-concentration atropine, as they protect the eyes and reduce discomfort caused by intense light. Additionally, for children using low-concentration atropine, photochromic lenses can alleviate visual symptoms. Photochromic lenses offer a 97% light transmission rate in clear indoor conditions and 15-22% transmission when activated outdoors, allowing light levels between 1,000 lx and 3,000 lx to reach the eyes—sufficient to delay myopia onset while blocking of UV rays. Compared to transparent myopia-control lenses, myopia-control lenses with photochromic features provide both effective light protection and myopia control, making them an excellent complement to traditional transparent lenses. There is currently no evidence suggesting that reducing outdoor sunlight intensity impacts the efficacy of myopia control strategies. For children and adolescents undergoing transparent myopia-control treatment combined with low-concentration atropine, or those who experience photophobia due to higher atropine concentrations, spend significant time outdoors, or engage in outdoor activities in high light-intensity environments, using photochromic myopia-control lenses from Maat Optical is highly recommended for enhanced protection and comfort.
Many people believe that sun protection is only necessary for exposed skin, unaware of the even greater harm that ultraviolet (UV) rays can cause to the eyes. UV rays penetrate the outer eye into the inner structures, affecting the conjunctiva, cornea, lens, vitreous, and retina. This can lead to conditions such as conjunctivitis, keratitis, pterygium, pinguecula, cataracts, retinal degeneration, and other serious eye diseases. This is where photochromic sunglasses come into play. These advanced lenses automatically adjust to light conditions, darkening in response to UV exposure and becoming clear indoors. By providing UV protection and adapting to changing environments, photochromic sunglasses offer not just convenience but also enhanced protection. As the saying goes, "Where there is strength, there is a counterforce." The stronger the UV rays, the stronger the protection your sunglasses should provide. Eye sun protection, especially with the right technology, can effectively counter UV damage. Sunglass UV Protection Index The UV protection of sunglasses, including photochromic sunglasses, depends on their UVB and UVA protection ratings. UV protection is usually classified into two levels: Level 1 offers 90% UVA and 99% UVB protection. Level 2 offers 70% UVA and 95% UVB protection. The standard is based on the visible light transmittance (transmittance = transmission ratio). For sunglasses with 30% transmittance, UVB transmission is ≤1.5% (30% × 5%), and UVA transmission is ≤15% (30% × 50%). Simply put, UVB <1% and UVA ≤5% are ideal. Photochromic lenses can meet these requirements while automatically adapting to light changes, providing optimal comfort and protection in various conditions. Lens Type Lens Category No. Visible Light Transmittance UVB Transmission Ratio (280nm-315nm) UVA Transmission Ratio (315nm-380nm) Light-Colored Contact Lenses 0 80%- ≤5% of visible light ≤ visible light 1 43%-80% Sunglasses 2 18%-43% ≤50% of visible light 3 8%-18% ≤1% Special Purpose Lenses 4 3%-8% ≤25% of visible light E-SPF Sun Protection Index E-SPF (Eye-Sun Protection Factor) is an indicator of the UV protection performance of lenses and the degree of protection they provide to the eyes. It rates any type of lens, including photochromic sunglasses and regular sunglasses. Generally, the higher the E-SPF value, the better the UV protection. The E-SPF value of regular eyeglass lenses ranges from 3 to a maximum of 25, with E-SPF 25 being the highest value for high-transparency, colorless lenses. Sunglasses can achieve an E-SPF value of 50+. In some cases, photochromic lenses can offer superior protection, as they transition from clear to dark based on UV exposure. For instance, on bright days, photochromic sunglasses can automatically adjust, reducing the need for multiple pairs of eyewear. E-SPF Index Lens Type Application Range Wearing Recommendation E-SPF25 Colorless and photochromic lenses Suitable for maximum protection of colorless and photochromic lenses Suitable for daily wear E-SPF15 Colorless and photochromic lenses Suitable for colorless and photochromic lenses with the highest cost-performance ratio Suitable for daily wear E-SPF10 Colorless and photochromic lenses Suitable for basic UV protection of colorless and photochromic lenses Suitable for daily wear UV400 Index The UV400 index refers to the UV protection factor, meaning the lenses block of UV rays. Specifically, it indicates that the average transmittance of UV rays below 400nm should not exceed 2%. The damage caused by UV rays depends on their wavelength, exposure time, intensity, and the strength of the eye’s natural defenses. Lenses marked with UV400 can block of harmful UV rays, making them the best option for UV protection. In simple terms, UV400 lenses control light transmission below 400nm, keeping it within 5%, reducing UV exposure, and protecting against cataracts, macular conjunctivitis, and retinitis. Photochromic sunglasses, especially those with UV400 protection, are an excellent choice for people engaged in outdoor activities like fishing or skiing, as they provide comprehensive UV protection while adjusting to varying light conditions. Maat’s newly released 1.56 UV400 photochromic lenses offer UV protection and are TUV certified, making them an ideal choice By choosing photochromic sunglasses, you are not only protecting your eyes from harmful UV rays but also ensuring comfort in both bright sunlight and low-light environments. This makes them a versatile and practical option for everyday wear.
