Difference Between Driving Glasses And Night Vision Goggles
The special effect of polarized glasses is to eliminate and filter the scattered light in the beam of light effectively so that the light can be put into the visual image of glasses with the right track, and the field of vision is clear and natural. The effect of night vision goggles is that they allow the wearer to observe the surroundings at night without being affected by light. For example, aviation accidents can be greatly reduced through the use of navigation winches equipped with forward-looking infrared cameras on aircraft and by requiring pilots to wear goggles fitted with night vision goggles.
Can I get a prescription for contact lenses?
Once a contact lens prescription is established, you are entitled to a copy. In some cases, this may occur after a diagnostic match. In many typical GP lenses and special designs, such as bifocal, annular, keratoconus, or postoperative, it may take several examinations before a successful match can be made and a prescription can be provided. If contact lenses are not issued by a doctor, it is important that whoever dispenses them is completely accurate. A soft lens Rx usually includes lens material name, design, power, base curve, and diameter. GP lens prescriptions usually have this information and more, like perimeter curve radius, center thickness, special perimeter design, and optical area diameter.
How to buy anti-blue light products?
In order to further standardize anti-blue light products and make all kinds of products effectively protect eye health, relevant standards have been formulated. Based on the different effects of blue light in different bands on the human body, the transmittance of blue light in each band is required in the standards.
For example, in the band range of 415-445 nm, the transmission ratio of light is less than or equal to 80%, and more than 445 nm, it is greater than 80%.
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.
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.
Pay attention to the frame
The frame stability is good, in line with the shape of the customer's face. Usually, you should not choose a rimless frame with easy deformation, to ensure that the curvature of the front surface of the frame and the wearer's forehead arc is consistent. The frame must have enough vertical height, which can be selected according to the type of lens selected, otherwise, it is easy to cut off the near or far part when cutting the edge.Adjust the front angle of the frame based on the facial features of the wearer to match the frame with the face, which helps to maintain enough gradient field of vision.
HINDAR blue light blocking glasses
With advanced equipment, system production, and strict management, they adopt German technology and PARUPU lens geometric structure owned by HINDAR OPTICE LAB, which can effectively block various kinds of blue light, ultraviolet light, and other different wavelengths, to protect the health of eyes. Since its inception, Hindar has enjoyed a lot of popularity, and while it has achieved some good results, it has not slowed down and is still striving to become the top brand in the industry.
