What does IOP mean?

Untitled Intrafile Pressure (IOP) is the pressure that occurs when the contents of the eye, such as the aquatic aquifer, crystals, and vitreous, act on the wall of the eye and exceed atmospheric pressure. Normal and stable intraocular pressure depends on the dynamic balance of ocular volume, rate of hydrocarbon production and rate of hydrocarbon outflow. Generally speaking, the volume of the eye is relatively stable, with aquatic aquifer formation and outflow being the main factors affecting intraocular pressure, the latter being more important.

Do reading glasses make your magnifying glass equal?

Most magnifying glasses with a lens shape are biconvex mirrors (handheld magnifiers, chandelier magnifiers, pocket magnifiers, keychain magnifiers, etc.) or flat convex mirrors (bar magnifiers and dome magnifiers), but reading glasses is a concave lens.

Do you need two pairs of glasses?

This is the right way to prepare two pairs of glasses to prevent the focus adjustment and radiant force from shifting. If a person with deep myopia is visible far away and close, the above abilities gradually become dysregulated. When you fit your glasses, the degree of lens is selected based on the vision measured with a long-range vision meter. Looking far, the distance between students in both eyes is also the widest.

What is the lens material?

Currently, 5 main materials:
Glass glass lenses are one of the best lens materials to provide visual clarity and high scratch resistance due to hard surfaces. However, glass lenses are heavy and thick, and have low impact resistance. ...
Plastic plastic (CR-39) is a standard glass lens material. ...
Polycarbonate Polycarbonate lenses have a higher refractive index, higher impact resistance and better UV protection compared to standard plastic lenses.

What glasses are best for reading and remote vision?
