How to choose contact lenses if you are nearsighted and sensitive?

People with dry and sensitive eyes often find it easy to encounter issues when buying contact lenses. Even though others wear them comfortably, they may experience itching and pain when it's their turn. In fact, people with sensitive eyes have poor tear film stability and high corneal sensitivity, so the requirements for various parameters of contact lenses are higher. So, how should those who are nearsighted and sensitive choose contact lenses? Today, we bring you a wealth of practical advice.

When purchasing contact lenses, material is the top priority. While many things are not necessarily better when more expensive, this holds true for contact lens materials as well, especially between silicone hydrogel and water-based hydrogels. Although silicone hydrogel is several times more expensive, it can achieve an oxygen permeability DK/t of over 100, which is 6 to 8 times that of water-based hydrogels. To enhance comfort, the oxygen supply to the eyes must be sufficient. Additionally, its high water content helps retain moisture in the eye, reducing the risk of corneal hypoxia and preventing allergic reactions.

The cleaning and disinfection of contact lenses is an important step in preventing allergies. If your eyes are prone to allergies, choose a gentle care solution. To prevent bacterial growth, it's essential to regularly disinfect the lens case and tweezers. Before putting on your lenses, make sure to thoroughly clean your hands!

For myopia patients, the selection of prescription is crucial. Friends with prescriptions should pay attention to whether the prescription for contact lenses is accurate and suitable when purchasing them. In most cases, the prescription for glasses needs to be converted into the prescription for contact lenses. The higher the myopia, the greater the difference. It's best to consult a professional optometrist for a detailed eye examination, which can also ensure proper fit of the base curve.

Finally, regular eye check-ups are a strong safeguard. To ensure that the use of contact lenses does not harm your eyes and to prevent and detect many potential risks, those with sensitive eyes should definitely have regular ophthalmic examinations. If you notice symptoms such as redness, swelling, pain, or abnormal discharge from your eyes, stop wearing them immediately and consult an ophthalmologist. It's best to be cautious in all matters.
