How do prism glasses work?
Prism glasses rearrange the images by bending the light and moving the images the eye sees to the desired position. They can align?with what each eye sees, eliminating the double image that the brain interprets. When the images seen by both of your eyes are rearranged, the light is redirected to the right position in the retina of each eye. The brain fuses these two images together to form one clear image.

Consider the elements of frame comfort.
What we need to know is that the frame exists first as a positioning device for the lens, and secondly as a beauty. The pupil is consistent with the optical center of the lens, so it should not be too high or too low. The horizontal direction is not skewed, and there is no one high and one low phenomenon. Bilateral symmetry is a standard for manufacturing enterprises. Non-mechanical symmetry is for the wearer. The frame should be adjusted according to the size of the wearer's face. The frame is not easy to slide down, and frequent slide is prone to the phenomenon that the pupil is too high and low to match the face.
Recommended Glasses for Heart Shaped Face
Wayfarers frames: to balance out a wider forehead is by finding frames that have wide, prominent endpoints that extend out past your temples. This can draw the gaze up and away from your cheekbones, making your eyes the focal point. So, the wayfarers frames are recommended.
Cat-eye frames: if you do not know how to choose the best glasses for heart shaped faces, you can try the cat-eye frames glasses. They can be quite versatile and help contour your face, either balancing or highlighting prominent features.
Aviator frames: the last glasses for heart shaped face we want to recommend is the aviator glasses. They can work to draw the eye downwards and flatten the bottom part of your face. The aviator frame glasses can also add a balanced look and soften prominent angular features.
Prepare a few pairs of glasses
Many people now have a 'reserve' of glasses. For example, you can choose two pairs of glasses. One pair is for daily use, and the style should be relatively simple and traditional. The other pair is for use at gatherings or weekends and can be as cool as you want. The more conservative style is a thin and bright metal frame that matches the shape of your face. For the other pair, you can choose a flat plastic frame or a shiny polished metal frame with a unique shape.
Choose the right lenses for blue light glasses.
Since visible light is made up of yellow, green, and blue light, the blue lens blocks the blue light, leaving only yellow and green light. Yellow plus green is yellow, so what we see is a yellow lens. If it is viewed from the side, we will find that the lens is also transparent, with no background color, and most of it is yellow-green. The dark yellow blue lens appears chromatic aberration, and it can be more serious. So to block blue light and do not hurt an eye again, you had better choose light yellow lenses to prevent blue light.
What Is Bifocal Lens?
Changes in vision seem to be related to age. Presbyopia, a common eye condition that occurs in middle age, causes changes in your eye’s ability to focus. But this condition can be corrected by wearing bifocal glasses.
Bifocal lenses are divided into two parts to accommodate two different prescriptions in one lens. One area of the lens will have one prescription (usually distance) and a segment in the lower half will have the other (usually near vision).
The bifocal glasses were invented by Benjamin Franklin, who solved his own vision problem by taking the lens from his reading glasses and distance glasses and cutting them in half. Then remade the cut lenses into a single pair of bifocals and put the distance lens on top and the reading lens on the bottom.
