The style of prescription glasses
Choose the material, and then choose the style. The width of the appropriate frame should match the distance between the two pupils to ensure that the eye can pass through the optical center when looking at things. Choose the right style according to your face shape. Generally follow the complementarity principle, such as choosing square frames for round faces and round frames for square faces. After choosing the frame, you should try it on for a while to see if the weight is appropriate and the style is suitable.
Understand blue light correctly.
Blue light has been shown to affect the body's circadian rhythms, with too much exposure to it late at night from gadgets such as mobile phones disrupting a person's ability to fall asleep. Therefore, it is recommended that people limit screen time two to three hours before bedtime and set their devices to night mode to reduce glare, relieve eye fatigue and minimize blue light at night. However, as we learn more about blue light, not all of it is bad for us. Blue light has been found to play an important role in maintaining health, such as regulating the secretion of hormones in living organisms. Blue light helps prevent reduced night vision and has been shown to benefit refractive development in adolescents and minors.
Brick-and-mortar stores have fewer customers.
Brick-and-mortar stores are known to have a significantly smaller customer base, targeting a particular county or even a particular region and population. Mainly aimed at young students.For physical stores, their income range is relatively narrow. Therefore, in order to make more money, every physical store can only make a profit by raising the single sale price. Online stores attract consumer demand from all over the country and the world through the Internet.
Is the prescription for glasses the same as for contact lenses?
A prescription for contact lenses is not the same as a prescription for regular glasses. The two types of glasses are quite different because glasses are located about 12mm from the eye, while contact lenses are located directly on the surface of the eye. If you want to wear both contact lenses and regular glasses, you'll need two different prescriptions. Contact lenses are worn in the eyes, and the frame is at a distance from the eye, although the distance is not large, definitely can affect certain degrees.
How to measure pupil distance?
You can ask your optometrist for this data, or if you have an extra pair of glasses, please send it to the merchant with your printed order and they will record your pupil distance value from it to ensure that your lenses have an accurate vision center. They will send you your new and old glasses together. The average pupil distance for adults is usually between 60mm and 66mm.
The role of blue light blocking glasses
Blue light blocking glasses can effectively isolate ultraviolet rays and radiation, as well as filter blue light. They are generally used when watching computers, TVs and mobile phones. In daily life, especially office workers, they often feel eye fatigue, dry and sore eyes, which are all caused by staring at the electronic screen for a long time.
Blue light blocking glasses can effectively reduce the damage of blue light to the eyes. The blue light blocking lenses can effectively block harmful blue light within a certain distance, resist the damage of lens diseases to the eyes, and reduce the visual fatigue caused by blue light. Outdoors can also reduce the discomfort caused by strong ultraviolet rays to the eyes, and avoid the damage caused by ultraviolet rays to the eyes.
Our eye protection should be always all-time, and we can’t rely on blue light blocking glasses. It can only block some of the blue light’s damage to the eyes. Whether studying or working, you must pay attention to the rest of the eyes and try to reduce the brightness of the electronic screen. More importantly, developing good eye habits is better than anything else.
What are optical frame glasses?
Optical glasses are transparent medium lenses. A pair of glasses usually consists of a lens, lens ring, nose pad, and temple, etc. The main materials are metal, plastic or resin, natural materials, etc. Through the refraction of the light, the central target can be clearly seen, thus playing a role in vision correction for the eyes with refractive abnormality.
