Duration of wearing sunglasses after LASIK surgery There is ultraviolet (UV) light in our environment that is harmful to our eyes. It is essential to protect the eyes from these waves and everyone should wear appropriate sunglasses in the open environment during daylight hours. It is necessary to wear sunglasses after eye laser surgery or PRK. It is necessary to use suitable sunglasses for 6 months after the operation. If sunglasses are not used after the operation, the patient may experience corneal opacity. Important features of sunglasses Features of sunglasses that should be used: - 100% protection against UVA and UVB rays - The glass of the glasses should be dark and do not use light brown glasses or bright colors - Glasses should be light and comfortable - The dimensions of the glasses should be such that they protect your eyes all around and not be too small The question that may arise is whether sunglasses should be used only on sunny days and outdoors? In response, it should be said that due to the sensitivity of the eyes after the operation and the need to protect against strong light, dust and accidental contact with the eyes, the use of sunglasses in the outdoor environment becomes more necessary. Wearing sunglasses is not only for sunny days. Harmful ultraviolet rays are also present in cloudy weather and sunglasses should be worn. Also, in the first days after LASAK surgery, you may need to wear glasses at home and indoors, which is normal and there is nothing to worry about, and after the first week, you usually do not need to wear glasses at home. After the surgery, they may sometimes suffer from glare due to dilated pupils and the light easily enters the eyes, so wearing sunglasses is also helpful in this situation. **Read more:** **All About** **Refractive Defect Surgery**
