Should I wear glasses all the time for myopia?
Wearing glasses is more to correct your vision and protect your eyes, so as not to worsen myopia. If you are nearsighted but don't wear glasses, it will have a lot of impact on your eyes. First of all, after a person is nearsighted, seeing distant things requires a lot of adjustments to the eyeballs, which will make your eyes tired easily. Over time, your myopia will increase quickly. When we are nearsighted, sometimes the myopia of the two eyes is not the same. If we do not wear glasses and correct vision, this will affect the normal development of vision. The difference between the powers of the two eyes may become larger and larger, which is easy to cause a squint. After myopia, if you want to see far away things clearly, you need to squint your eyes harder to see clearly. Therefore, some nearsighted eyes often squint when they are not wearing glasses. However, the action of squinting will cause the upper eyelid to form a pressure on the eyeball, and squinting for a long time can easily cause amblyopia. Squinting your eyes for a long time will also make your eyes smaller and affect your appearance. Therefore, once your myopia exceeds 200 degrees, you must wear glasses in time.

Put into the lens box when not in use.
When taking off glasses, many people will easily hang them on the head, collar, or casual display, so that glasses often suffer a variety of damage. To do this, fold the glasses and place them face up in the case. Do not place your glasses in direct sunlight or in high temperatures, as heat can easily peel off the film on the lens. For example, in summer, the glasses are exposed to direct sunlight in the car for a long time, which is easy to cause lens stripping.
What is the difference between sunglasses and polarized glasses for fishing?
Ordinary sunglasses reduce the sensitivity of the light, reduce the intensity of the reflection, and reduce the glare of strong light. Wear the glasses to see where there is a reflection on the surface of the water, the reflection still affects the vision.
Polarized sunglasses used for fishing can not only reduce the sensitivity but also refract the reflections to prevent the strong light from stabling the eyes. Wearing polarized sunglasses to see the reflections on the water surface will not see the reflections. Also, you can see underwater fish and scenery ( Depending on the clarity of the water), it is not an exaggeration to say that polarizers are an enhanced version of sunglasses.
What Are Progressive Lenses?
Progressive lenses have grown in popularity and are one of the most common solutions to treat vision loss that occurs with age or presbyopia. This eye condition occurs when the eye loses some of its flexibility and ability to adjust to clear seeing objects at different distances. Presbyopia often occurs among adults who are over age 40 and is very easy to correct with a proper and prompt diagnosis.
Progressive lenses are often used to correct this eye condition. Progressive lenses are a modern alternative to bifocal glasses, which provides two prescriptions in a single set of glasses. Bifocal glasses are a better solution than carrying around multiple pairs of glasses. Progressive lenses were developed to resolve some of those common issues and to provide better aesthetics. Progressive lenses provide a smooth transition and can accommodate up to three prescriptions and are a replacement for both bifocals and trifocals.
