The Identification of the Quality

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.
Why the lens coating is not uniform?
Sometimes we find differences in the color between the convex and concave surfaces, between the center and the edge of the lens, and the anti-reflection effect between the convex and concave surfaces. his is mainly because the lens coating is that it is plated on one surface and then turned over to another surface. And Areas with small curvature changes are easy to coat. So the center of the lens has reached the desired thickness of the film but the edge has not. At the same time, the different curvature of the convex surface and concave surface causes the different coating speed. So the surface of the lens will show green in the center and lavender red or some other color at the edges.
Pair clear glasses with natural makeup.
Clear glasses and light makeup can make the focus of others in the glasses, so it will not appear abrupt. With a plain color coat, there is no sense of violation, and it is playful. A frame without lenses can be an accessory to give you a different feel.
Regular eye hospital examination
They must go to the formal professional ophthalmology for optometry and glasses. Wearing glasses after they suffer from myopia, is to correct refraction and clear view. Another important role is to prevent the loss of balance between the adjustment and aggregation functions of the eye. Before getting glasses, they need to go to the hospital for pupil dilation. Many parents are afraid that dilating pupil has a bad impact on their children's study, or afraid that dilating agents will affect the health of their children, so they ask their children to choose computer optometry for glasses. Failure to dilate the pupil and optometry will cause harm to the child's eyes.
How Should Glasses Fit?
Make sure your pupils align correctly. The combination of frame, arm, bridge, and lens measurement can affect the placement of your pupils within your lenses, which is essential to the proper function and comfort of your prescription. To ensure glasses fit properly, the pupils should align horizontally in the center of your lenses.
Also, you should consider your face shape. When choosing a pair of suitable glasses, you should consider what face shape you have.
