Make Your Eyes Bright
Modern glasses usually have nose pads in the middle of the lenses and soft pads where the left and right arms rest against the ears. People who love beauty or are not used to wearing glasses can choose to use contact lenses to correct their vision.
The first type of glasses has frames.
In terms of the function of the lens, it can adjust the amount of light entering the eye, correct vision, protect eye safety, and clinically treat eye diseases.
The function of the spectacle frame, in addition to the role of the lens holder, to form the glasses worn by the human eye, also has the role of beauty and decoration.
How to clean and maintain glasses frames.
The process of cleaning glasses frames is very simple. You can apply soap and detergent to the frames, then rinse thoroughly with warm water, focusing on cleaning the nose pads of the frames.
If the contamination is light, you can wipe it with a soft paper towel or glasses cloth.
Do not place glasses in direct sunlight or heat packs to prevent frame deformation and fading.
Frame glasses made of natural materials should not be cleaned with ultrasonic waves, which will easily cause the frame to be deformed and damaged by heat.
The second type of glasses is contact lenses.
Contact lenses are lenses that are worn on the cornea of ​​the eye to correct vision or protect the eye. According to the hardness of the material, it is divided into three types: rigid, semi-rigid, and soft.
Contact lenses bring great improvement in appearance and convenience to patients with myopia, hyperopia, astigmatism, and other refractive errors.
Precautions when wearing contact lenses:
1. If irritation occurs, remove the lens and recheck for dust or fluff. Rinse with contact lens solution before wearing.
2. Please do not open the two covers at the same time, so as not to reverse the cover and stagger the lenses of different degrees.
3. When wearing astigmatic lenses, please use the angle indicators at both ends of the lens to attach the lens horizontally to the cornea.
4. Make-up can only be done after putting on the lenses; make-up can only be removed after removing the lenses.
5. Keep your glasses-wearing fingers dry. If there is too much moisture on the fingertips of the fingers wearing glasses, the lenses are easy to stick to the fingers when wearing glasses, and it is difficult to put them into the eyes.
6. If the lens fails to enter the eye during wearing, do not rush to wear the lens again, but rinse the lens thoroughly before wearing.
The pros and cons of wearing glasses.
Advantage.
1. Wearing glasses can correct vision.
Myopia cannot focus on the retina, because distant light cannot be focused on the retina, resulting in a blurred vision of distant objects.
2. Wearing glasses can reduce visual fatigue.
Shortsightedness without glasses will inevitably lead to glasses fatigue. After wearing glasses normally, the phenomenon of visual fatigue will be greatly reduced.
Shortcoming.
1. The bridge of the nose that the frame glasses will press is very uncomfortable.
2. The interpupillary distance of the glasses is inconsistent with itself, which can easily cause euphoria and eye fatigue.
Now, both glasses with frames and contact lenses can be used for decoration.
