Which kind of soft or hard contact lenses is healthier?

For contact lens enthusiasts, soft contact lenses are a relatively common choice, while hard contact lenses are a little unfamiliar. But when it comes to oxygen penetration performance, hard contact lenses are worthy of the king. So, which kind of soft contact lenses or hard contact lenses is healthier?

The material of soft contact lenses and hard contact lenses is different, and the care method is slightly different, and the characteristics are not completely consistent. As can be seen from the naming, they are mainly distinguished from the perspective of material and texture. Soft contact lenses present a light and soft texture, with good physiological compatibility, and can be more attached to the surface of the eyeball, and provide a higher matching degree in comfort. According to the material, they can be divided into two types: hydrogel and silicon hydrogel. The optical properties of hard contact lenses are stable and have slightly poor comfort, but they win the porous material architecture and excellent oxygen permeability.

From the perspective of oxygen permeability, hard contact lenses have great advantages, soft contact lenses are more likely to deform and cause corneal hypoxia and other problems, and high oxygen permeability hard lens is obviously not prone to such problems. However, the price of hard mirror is not close to the people, the technical requirements are very high, so far wear the crowd is still a minority.

Hard lenses and soft lenses are very different in use. Soft contact lenses are worn during the day and must be taken off before bed, while hard contact lenses are worn at night and removed after waking up. Hard contact lenses also have longer adaptation periods than soft contact lenses, and may sometimes take up to a month. Because of this, the specific situation of each person is not the same, the suitable type is not the same, with the mirror to consider health, but also consider which type. But the same is that wearing glasses need to pay attention to personal hygiene habits, otherwise it is easy to bring adverse effects on the cornea, and there is a high probability of causing various complications.
