Powerful Function of Lens From KOALAEYE
The lens is flat with high clarity. The glasses have an anti-scratch coating, an anti-scratch coating on both sides of the lens, which can effectively reduce the wear of the lens and prolong the service life of the glasses. However, the scratch-resistant coating is not 100% scratch-free but is more scratch-resistant than uncoated lenses. They have Super Hydrophobic coatings, Oleophobic coatings, and ultraviolet protection functions. Glasses are not only fashion accessories but super weapons to protect eyes and restore clear vision.
How to Choose Glasses for Long Face?
Bold shapes and eyeglasses with decorative details are also a smart choice since they help draw attention to your eyes and can add width to your face. Be sure to avoid narrow or rectangular shapes, which can make your face appear longer.
Square glasses: if you have a long face, you can try square glasses whose sharper corners can help to balance out the length of your face and complement your narrow features. Choose frames that are slightly wider than your cheekbones to make your face appear broader.
Two-toned glasses: if you have a long face shape, the two-toned glasses would be a good choice. The color-top frames create an optical illusion that draws focus upward toward your eyes rather than to the length of your face.
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.

How to buy prescription glasses online
Consumers should choose different styles of frames according to their age and professional characteristics. Because everyone has different face shapes, different interpupillary distances, and different diopters, the size of the frames should vary from person to person.
Lenses are divided into glass lens, resin lens, and PC lens, and you can choose according to your preferences. The glass lens has a stable refractive index, good abrasion resistance, and stable optical performance, but it is relatively heavy and easy to break. Resin lens with high light transmittance is light, safe, and not easy to break, but the surface is easy to wear. PC lens has a high refractive index, but the surface is easy to wear.
What's the use of color-changing lenses?
Photochromic lenses are lenses that are transparent indoors (not unlike our usual lenses) but darken when exposed to ultraviolet light. When no longer exposed to ultraviolet light, the lens will return to its original transparent state under the influence of ambient temperature. Color-changing lenses provide UV protection. It can provide adequate eye health protection, reducing exposure to sunlight. And it can reduce the risk of cataracts or other eye diseases. People who wear glasses, only need to have one pair of glasses indoors and outdoors in the sun, and they do not need to change glasses frequently.
