Then, in 2000, Walmart began offering high-end Carl Zeiss lenses. Customers have noticed the change and they continue to strive to become a leader in eyewear quality. Walmart has led the way in applying anti-reflection and anti-scratch coatings to its lenses.

The upgrades now underway will continue to deliver on that promise.
The Cons of Transition Lenses
However, besides the pros of transition lenses, there are also some negative voices of transition lenses.
The transition lenses are not effective in cars because the windshield blocks the UV rays so that transition lenses won’t darken very well in the car.
Different brands of photochromic glasses have different levels of darkness and different reaction times. So, you may need to ask the doctor to find the brand that works best for you. Transition glasses are affected by colder weather. So it means that it may take a bit longer to react to UV rays in winter. Most transition lenses are not polarized which may result in harsh glares.
So, if you need transition glasses, try Koalaeye Optical, which provides the Koalaeye photochromic glasses. Besides these, Koalaeye Optical also provides other kinds of glasses, such as blue light blocking glasses, polarized sunglasses, progressive sunglasses, and so on.
Have a try and confirm the front and side of the glasses.
Confirmation data: pupil height, flat frame surface, size of frame surface, the harmony of nose arc, the contact area of nose support, size of temple bend. Finally, remember a big principle: You should have no sense of pressure, and in a small range of motion, the frame does not shift. Good glasses should be perfectly integrated with the face so that people can not feel the existence of glasses. Good design is invisible. The lens above 800 degrees will be slightly heavy, so it is not recommended to choose the elastic temple and smooth metal temple. The temple is too slender, and at the same time is all metal, easy to slide frequently.
What are the advantages and disadvantages of bifocal reading glasses?

But different areas have obvious intervals, and the appearance is not beautiful. The middle distance is fuzzy. They need to adapt to the period. Bifocal reading glasses lens is divided into two parts, and the degree of the two parts is not the same. The upper part is the mother of the flat area to see far, and the next part is the child of the reading area to see near. There is an obvious interval. The appearance is not beautiful. There is no transition area between two different areas, so its vision is fuzzy, easy to produce a 'jump image'. Long-term wearing will make people dizzy or fall down when climbing stairs.

Blue light is an important part of natural light, and it is visible light with a wavelength of 400nm-500nm in the spectrum. Blue light can be divided into short-wave blue light (harmful blue light) and long-wave blue light (beneficial blue light). Short-wave blue light harms people’s vision and causes specific diseases, while long-wave blue light helps people maintain normal physiological functions, regulate biological rhythms, and treat specific diseases.
Blue light can be seen everywhere in daily life. In addition to blue light in the sun, electronic products such as TVs, computers, mobile phones, ipads, and LED lights also produce blue light in our daily.
Your glasses are not symmetrical.
If one side of the frame looks higher than the other, you need to adjust the arm. If the right side is higher than the left, gently bend the left arm at the hinge or where the arm bends behind the ear. If the left side is higher than the right, gently bend the right arm at the hinge or where the arm bends behind the ear. Adjusting the frames a little at a time may damage your glasses. Place your arms in warm water to make them easier to adjust. Use only warm water from the tap. Don't use boiled water! Because it affects the coating on the lens. If one adjustment is not in place, it can be adjusted several times, and the above methods can be comprehensively used. If the adjustment is really bad, then you have to go to the optical shop to ask the staff to adjust.
