Cat-Eye Reading Glasses

The features of Cat-Eye Reading Glasses:
1. The lens shape of Cat-Eye Reading Glasses is relatively wide. Due to the collective effect of presbyopia nearsightedness and the habit of reading and writing, the axis of monocular vision on the lens should move down and inward 2.5mm when the lens is farsighted (flat), while the pupil is generally around the middle line of the lens shape when the lens is flat. In order to make presbyopic glasses have enough field of vision, the type should meet the requirements of the upper and lower height greater than 30mm, not the smaller the better. The narrow type of the upper and lower 25mm is generally portable and used for temporary supplementary vision.

2. The front side of the Cat-Eye Reading Glasses is wide, but the OCD (horizontal distance of optical center) is smaller. Because the users of reading glasses are above middle age and have a plump face, the horizontal size of reading glasses is generally 10mm larger than that of optical frame, but the pupil distance of near use is 5mm smaller than that of far use, so the OCD value of women should generally be 58-61mm Men should be around 61-64mm. To meet both requirements, a larger diameter lens and larger epicenters shift during filmmaking are required.

3. Our Cat-Eye Reading Glasses are strong and durable presbyopic glasses are near-use glasses, the law of the use of presbyopic eyes is in the reading distance from 40 years old (+ 1.00d, that is, 100 degrees), every 5 years to add +0.50D(that is, 50 degrees) and in the use of the frequency of wearing dozens of times more than myopia glasses, so the parts of presbyopic glasses must be strong or high elastic material The anti-corrosion and anti-scratch performance of electroplating must be outstanding, and the hardening process of the lens should be better.
