Reading Glasses
At present, there are two prescriptions for reading glasses. One is to adjust the power of glasses with clear objects at close range, plus 1/3 of the power for adjustment. The other is to use low power that can see close objects clearly. The practice of many elderly people has proved that the latter one is better between two methods.
Why were eyeglasses invented?
Glasses are commonly used for vision correction, such as reading glasses and myopia glasses, but they are sometimes used for cosmetic purposes if special lenses are not available. Safety glasses provide eye protection for a construction worker or laboratory technician against flying debris. They provide protection against visible and near-visible light or radiation. Sunglasses can improve vision in bright sunlight and can protect your eyes from excessive UV damage. Special glasses can be used to view specific visual information. Sometimes glasses are used purely for fashion or aesthetic purposes. Even eyeglasses used to correct vision come in different kinds of styles, with frames made of plastic, metal, wire, and other materials.
The lifetime of contact lens
Traditional type: the replacement cycle is more than 3 months, not more than 1 year, that is, we say we abandon after one season, and we can abandon after half a year and a year.
Frequent-change type: the replacement cycle is more than 2 weeks, not more than 3 months, that is, we often say that we throw them after 1 month or two weeks.
Abandoned type: as a one-time use, common for the day use.
Contact lenses, like food, have an expiration date. For example, the shelf life of daily contact lenses is one day (after it is opened), and can not exceed this time. And the life span of a pair of glasses depends on how long you use them each day. Although different lens materials determine different wear times, we recommend that soft lenses should not be worn for more than 8 hours per day (do not wear soft contact lenses to sleep). Traditional contact lenses can be used for a long time, so the lens is easy to produce protein-lipid deposition, and then they are easy to cause eye surface inflammation and hypoxia reaction. If conditions permit, it is recommended to choose the frequent-change type and discard type, the shorter the cycle, the healthier.
Why you should be careful when choosing blue-light-blocking glasses?
Prices of blue light blocking glasses in the market now range from 200 to 300 yuan to several thousand yuan. According to the report, current eyewear standards do not prescribe the effects of blue-resistant lenses, and consumers are advised to choose blue-resistant lenses with caution. It is recommended that people with specific eye diseases such as macular disease, age-related macular degeneration, macular hole, and diabetic fundus lesions should choose anti-blue light glasses according to the advice of an ophthalmologist.
Optical laboratory
The two main laboratories provide different services. The Eyewear Repair Lab is made up of two technicians to provide solutions to the most difficult repair work for network eyeglasses repair customers. The prescription lab is staffed by optometrists and tasked with delivering about 30 prescription orders a day to retail customers and Internet customers. The lab is in charge of cutting lenses, forming rimless and semi-rimless frames bit mounting, edging, and finishing, and has anti-reflective and anti-UV coatings.They provide very competitive prices because all repairs are carried out in our own optical laboratory.
Titanium glasses are very popular.
Nowadays, the relatively popular titanium glasses, taken from titanium metal light, are not easy to break, are elastic, have super corrosion resistance, have a good touch, are non-allergic, and have memory characteristics. They have become a new type of glasses frame material. So that the wearer will no longer wear traditional overweight glasses, with no long-term pressure on the bridge of the nose caused by muscle oppression, and another discomfort. And they do not have to worry about glasses after long-term use of discoloration and lackluster and other problems. The titanium frame is more and more popular and becoming a fashion. Especially the high-end business elites praise pure titanium frame. No matter from the material, lens frame, suitable crowd, they can say to be an especially good choice!
Choose a quality progressive lens.
Superior progressive lenses provide a better viewing experience. They also remove any distortions you might feel when reading what's in front of you. Lenses can also be coated with special coatings. Anti-reflective coating can prevent glare on the road, and anti-scratch coating can reduce wear marks.
