What do the number of 1.61 and 1.67and1.74 stand for ? What is the difference between them?
They refer to the refractive index of the lens, the larger the number the lighter and thinner the lens, the higher the refractive index and the better the anti-blue light effect, all three sizes can match most prescriptions, but for Sphere (S,Sph) over ±4.00 1.67 or 1.74 lenses must be used
How do I add a prescription?
Please send your optometric prescription information to helloyatllc@gmail.com
Please distinguish between left and right, basically it should contain SPH,CYL,Axis and pupil distance.
