Contact lenses are not for everyone.
Patients wearing contact with the cornea need to go through a doctor's detailed inspection of the visual acuity and external eye condition, whether the tear secretion is normal, whether the corneal fluorescein sodium is colored, and whether the fundus is diseased or not. Final optometry, check out the correct refractive power, and then measure the corneal curvature radius. Only after the above examination and approval by the doctor can wear contact lenses. In patients with dacryocystitis, severe trachoma, spring catarrhal conjunctivitis, keratitis, blepharitis, glaucoma, and diabetes, contact lenses should not be worn. Therefore, contact lenses cannot be worn by everyone. However, contact lenses have special therapeutic effects on certain diseases of the eye. For example, keratoconus with hard contact lens augmentation effect is better, soft corneal contact lens can be used to treat bullous keratitis. The use of soft hydrophilic contact lenses for high myopia is superior to spectacles, improving vision and reducing the effects of triple palsies. When the two anisometropia are too large to be seen in the glasses, contact lenses can be preferentially worn to reduce the symptoms of dizziness and double vision. After wearing a contact lens, the field of view is large, reducing the size of the retina image.
