ShadyVEU HD blue light blocking Glasses
The anti-reflective yellow and amber lenses are the best choices for outdoor vision protection, as they reduce high-intensity glare from bright lights (headlights, LED signs, etc.) at night. They are suitable for daytime driving with a clear vision, especially in low light conditions such as rain, haze, and winter. Yellow and amber-colored lenses help block out our computer screens, smartphones, games consoles, tablets, and TVs, helping to prevent melatonin suppression and thus helping wearers fall asleep faster.
They are suitable for sports, hunting, fishing, cycling, work, practical and construction work, day driving, night driving, bright days, snow days, and low light conditions.

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.
What Are Progressive Lenses?
Your eyes change with your age. When your reach your 40s, you may find that it is difficult for you to focus between a book, a website on a computer screen and the conference room whiteboard. Progressive lenses are growing in popularity among people who need help seeing near, far and in-between.
Progressive lenses have grown in popularity and are one of the most common solutions to treat vision loss that occurs with age or presbyopia. Progressive lenses have a seamless increase in magnification from the top to the bottom of the lens, helping you see clearly at all distances with just one pair of glasses. The top portion of the lens enables you to see the far-away objects, the middle portion of the lens enables you to focus on the intermediate objects and the bottom to see objects close-up. The prescription changes little by little across the lens surface providing a gentle transition.
After knowing what the progressive lenses are, do you know what are the pros and cons of progressive lenses? If not, keep on your reading and we will show you some information.
How to do with it?
Wash your glasses once a week to avoid future accumulation. Remove the green goo with a soft cloth, a cotton swab, some mild dishwashing liquid, alcohol, and a soft-bristled toothbrush. Ultrasonic cleaning machines can remove dirt and green mud because vibration can do with micro-mud. This device is available in most optician stores, so you can have your glasses cleaned there. Just like anything we use, glasses need to be replaced. It is recommended that you replace the nasal pad with a new one every 6 months to keep it sanitary.
What Are High-Index Lenses?
High index lenses are eyeglasses lenses that are designed to be thinner and lighter than regular lenses. High-index lenses have a high refractive index than their conventional counterparts. So, they are generally recommended for people who have significantly high refractive errors and strong prescriptions for nearsightedness, farsightedness or astigmatism.
High-index lenses correct all types of refractive errors. And they are also available as single vision lenses, or a reading prescription that corrects presbyopia, such as in a bifocal or progressive lens.
High-index lens has a higher refractive index and which is ranging from 1.53 to 1.74. A lens with an index of 1.74 could be up to 50 percent thinner than a regular plastic lens with an index of 1.50.
The Cons of Rimless Glasses
As there is no frame around your glasses lenses, the rimless glasses may be more likely to break. If you are not very careful with your glasses, you may have to replace them on a constant basis.
Rimless glasses are higher than other framed glasses because of the details that go into this style. In fact, the rimless style needs more work and time. So, making this kind of style is more time-consuming. So, rimless glasses are expensive than framed glasses.
From the above information, if you like rimless glasses, you can try them. Thus, you can buy them from Koalaeye Optical, which is an online store and provides all kinds of glasses, sunglasses, and frames. So, try Koalaeye glasses and the glasses will be mailed for you with your great convenience.
