Transparent frames: as for glasses for round faces, the transparent frames aren’t going away anytime soon. Whether clear or with a faint tint, these frames are almost invisible from a distance and make it easy to clearly see the soft features of a round face. So, if you need a pair of glasses for a round face, try the transparent or clear frames.
Full-rim glasses: round faces look best against strong angular lines, while full-rim glasses can enclose and balance these features. So, you can take the full-rim glasses into consideration when choosing round-face glasses.
How to drive at night with glasses?
If you need to wear glasses while driving, you'll need special glasses when driving at night, because common lenses reflect oncoming lights, which produces a faint glare. This will reduce your visibility. It's OK to wear contact lenses while driving. As you get older, your eyes become more sensitive to glare. Ordinary sunglasses or goggles are only suitable for wearing during the day, driving at night will seriously affect the vision (national standards stipulate that light transmittance of night driving glasses must be greater than75%). Although the all-weather driving glasses can weaken the strong lights, the vision darkens and affects road safety which does not meet the national standards for driving glasses at night. You should choose functional driving glasses that can block strong light, glare and increase the field of vision. This can effectively reduce the glare of the car lights but can filter out the extra harmful light. When worn at night, it can soften the strong lights and make the vision clearer. In this way, the safety of drivers is ensured, the fatigue of eyes is alleviated, and the radiation damage of harmful lights to glasses is prevented.
What factors make you receive glasses on the same day?
Are your lenses anti-glare or anti-scratch? This may extend the time it takes you to buy glasses. Is your prescription complicated? If so, it could mean your lenses take longer to make. Your favorite frames that you tried out at the store are just for display, so you have to order frames for your glasses. If that particular frame style is in small quantities at the factory, your delivery may be delayed. Some optometrist offices and eyewear retailers have in-house optics LABS. These LABS can make some eyeglass lenses in an hour or so. But the power and design of the other lenses needed to be manufactured by an external optics lab, which took more time.
Why do you need blue-light-blocking glasses?
High-energy blue light would penetrate the lens and directly enter the retina, causing the atrophy and even death of retinal pigment epithelial cells. The death of light-sensitive cells will lead to vision loss or even complete loss, which is irreversible. Blue light at 415 nanometers to 455 nanometers is short, that is, high energy and harmful blue light. This band of blue light would penetrate the lens directly to the center of the macula, causing irreversible damage to the macula. Excessive intake of high-energy blue light would cause confusion of our biological clock, so the damage of blue light should be paid enough attention to.
What are the benefits of memory metal frames?
Memory metal materials are inherently lighter than metal materials, which can reduce the pressure on the bridge of the nose and skin. The memory metal frame is super elastic, so it never deforms, and it is so apparent that the temples on both sides of the frame line up with the ring. Because the bending can be automatically restored to its original state, the stability is comparatively strong. It has the benefits of high-temperature resistance, corrosion resistance, which will not cause skin allergy, and so on. It is a hypoallergenic lightweight metal for eyeglass frames that is strong and flexible. It is resistant to corrosion, making it proper for people who work, live or play sports in all kinds of outdoor weather conditions. The memory metal can be placed on the side of the face, making it easier and more comfortable to wear. The memory temples can freely rebound 180 degrees without deformation, making up for the insufficient effect of elastic β titanium. This kind of frame is not able to recover due to careless bending, and it has the function of restoring shape itself.
Benefits of Saddle Bridge Glasses.
The most common type of plastic bridge is called a saddle bridge. The style is very comfortable because it distributes the weight of the glasses over a larger area rather than focusing on smaller points, like adjustable nose pads. Saddles are known to cost less to repair because they have fewer moving parts and are possible to maintain their fitness. There is now a new saddle bridge-type transparent silicone cushion for a screw-type nose pad. It is made of medical-grade soft silicone. It can be bent and is very soft. To fit the curve of the nose, a plastic frame with a saddle or keyhole bridge can slip off the nose without proper support. Silicone is a soft and elastic material that can be formed according to the contour and shape of the nose.
Many traditional optical stores are complaining about a drop in customer numbers. When we analyze it, we find that the decline in customer numbers is divided into two aspects. The first is the decrease in new customers, which is mainly because the Internet and eye hospitals are fighting for customers from optical stores. The other is the loss of old customers, which is entirely because the optical store did not do the best service, especially the after-sales service.
