If you need reading glasses when using a computer, you may want to choose a lower reading glasses power. This is because most people view their screen from a greater distance from their eyes than when they are reading a book or a magazine.
However, if you need reading glasses for looking at something very close or very small, you may need a pair of stronger power glasses.
In most cases, when two reading glasses’ powers seem equally suitable, choose the glasses with the lower power. Picking reading glasses that are too string typically will cause more discomfort problems than reading glasses that are a little too weak.
How to wear clear frames with style?
A square face is all about softening the lines of the face, so it works well with round frames. The person with a long face should choose a bit bigger frame. It can make the proportion of the face-up and down more harmonious. The oval face is the standard face shape, and any frame is suitable. People with round faces are similar to those with square faces. If you have a round face, you can choose a square frame instead of a round frame, which will only make your face look rounder. The most important feature of a diamond face is high cheekbones, so choose a thick frame to visually weaken the cheekbones. For the triangular face, people can choose the frame of a half-frame design. Since the upper part of the face will be smaller in this shape, a half-frame design is necessary to balance the proportions.
The disadvantages of progressive lenses
- The field of view in the near and middle distances is relatively narrow.
- The adaptation time is longer and patients with greater astigmatism are not suitable for wearing.
- The peripheral aberration is large, and there will be large astigmatism in the periphery.
Different Types of Eyeglass Frame Materials
Acetate: The most popular frame material is acetate, also called Zyl. Zyl is a very cost-effective and creative option for eyewear and is extremely lightweight. The acetate frame material is also colorful.
Nylon: This frame material is used in some cheap eyeglasses. Nylon is strong, lightweight and flexible, and it can become brittle with age. Nylon is also a premier material for sports and performance frames, and also easily molded into today’s popular wraparound style.
TR90 Nylon: TR90 Nylon is durable, flexible, and lightweight. Glasses made with TR90 are extremely comfortable since they have a flexible quality. Besides, the TR90 Nylon frame material can bend under pressure and contour your face comfortably. So, it would be resilient to damage.
Ultem: Ultem resin is a flame-retardant and high performance thermoplastic. It comes with various features, such as high strength-to-weight ratio, heat resistance and high impact strength. This frame material is also durable.
β titanium refers to a particle titanium material that is completed by delayed cooling at the zero bound point state of titanium and does not belong to the alloy. Practical applications will often be processed into alloys to increase their applicability. Although the purity of β titanium is not comparable to pure titanium, its strength, fatigue resistance, and environmental corrosion resistance are better than pure titanium. It has higher strength than pure titanium and other titanium alloys, and the corrosion resistance is stronger and has better elasticity, It is not easy to deform, and is lighter.
Common sense of glasses maintenance
Do not wear glasses when doing strenuous exercise to avoid deformation caused by knocking. Take off your glasses when sleeping or lying on your desk to avoid distorting your glasses. Use special glasses cloth to wipe glasses, and can use water and dishwashing essence to clean. Avoid using paper towels, handkerchiefs, or clothes. Deformations of memory materials are not often demonstrated to prevent breakage of joints or welds. If it is uncomfortable to see things, or the frame appears obvious uneven, you need to take it to the optical shop to find a professional to adjust.
Japanese Charmant Group is one of the world's famous eyewear manufacturing enterprises. Since its inception in 1956, it has always been the leader of cutting-edge technology in the field of eyewear manufacturing. Charmant is a global titanium expert, and now the domestic market has launched 7 series of titanium, like Z titanium, etc., to meet the Chinese consumers’ pursuit of all ages for high-quality glasses and more comfortable glasses.
Among them, EX titanium is a patent developed by Charmant Group. Compared with common memory titanium, EX titanium has a more stable memory function and a more diversified design.The frame price of Charmant glasses is 1000 yuan above basically, from 1000 to 4000.
