We often say that the eyes are the Windows to the soul, so it is important to be very careful and careful when buying and wearing contact lenses.So, what kind of contact lenses are good contact lenses?
For contact lenses, the material is very important.On the packaging, all contact lenses will be clearly marked with material.In terms of the existing hydrogel and silicon hydrogel materials, although silicon hydrogel contact lenses are more expensive, they have better oxygen permeability and can maintain moisture and comfort for a long time.If you want to wear contact lenses for a long time, you should choose silicon hydrogel lenses.
Life cycle means the shelf life of the lens, which is one of the important parameters of contact lens.For the choice of using cycle, the wearing frequency should be taken into account. For frequent wearing, traditional contact lenses can be selected, which is of high cost performance. However, daily cleaning and care are needed, and for occasional wearing and seeking health, it is more recommended to buy short-cycle disposable lenses such as daily or monthly disposable lenses.
The choice of moisture content for contact lenses also needs to vary from person to person.Some people have insufficient tear secretion and are prone to visual fatigue. Choosing contact lenses with low water content can avoid aggravating dry eyes. If a lens with high water content is mistakenly worn for comfort, tears will be easily absorbed by the lens to replenish water.
In short, there is no uniform standard for the measurement of contact lenses, suitable for their own contact lenses is the best.In addition, contact lenses require direct contact with the cornea. For the safety and health of the eye, proper care and wearing must be followed. Once you have symptoms of discomfort, stop wearing them immediately and seek medical attention.
