How to protect your contact lenses?

When wearing contact lenses, do not drop any eye drops, and only use a special moistening solution for contact lenses. In daily life, we recommend that dry eyes can be relieved with lubricating fluid, but we do not advocate frequent use of lubricating fluid, so as not to make the eyes become dependent on lubricating fluid. The right way is to do blink training. The ingredients contained in the eye drops will remain in the lenses, which will cause certain damage to the eyes and pollute the lenses. Some eye drops can make the lenses tinted after use, which will affect the transmittance and a refractive number of the lenses and make the vision blurred. Ladies who need to make up should wear contact lenses before making up. When removing makeup, remove contact lenses before removing makeup, to avoid the makeup sticking to the lens and damaging the lens and eyes. Lenses should not be lent to others to avoid cross-infection of eye diseases. You can't wear contact lenses while swimming or bathing.

Progressive lenses and single vision lenses

Single vision lenses are the most commonly used prescription lenses. This lens type has a single field of view or a prescription ability of the entire lens and can be used to correct myopia (nearsightedness) or hyperopia (supervision).

Progressive multifocal lenses are lenses with different upper and lower powers for the upper part to see far, and the lower part to see near. The distance from the fixed power above the lens to the fixed power below the lens does not change suddenly, but there is a gradual transition between the two through the gradual change in refractive power.

Difference between green film and blue film

In addition to the usual hardening, anti-fouling, anti-reflection, anti-radiation, and other functions, the green film has remarkable anti-ultraviolet performance, suitable for people who work outdoors for a long time to use. In addition to the general hardening, anti-fouling, anti-reflection, and anti-ultraviolet functions, blue film’s anti-radiation ability is very good, and it is suitable for computer workers and other people affected by radiation greater.

The coated lenses were originally produced in green, mainly to distinguish them from the uncoated lenses. At 515 nm, the reflection increases the reflectivity by about 2%, so there is a contrast, and the green film is seen in the reflection. This film is the most standard anti-reflective film, and it is the best and oldest one available.
