What Should the Elderly Wear Sunglasses Pay Attention to?
When the sun is hot, the elderly can wear sunglasses, especially when going out in summer. Sunglasses have a good protective effect on the eyes. Excessive UV exposure in sunlight can accelerate the occurrence and development of senile cataracts and age-related macular degeneration. Wearing sunglasses can block the ultraviolet rays in the sun and protect the eyes. So what should the elderly pay attention to when wearing sunglasses?
Middle-aged and elderly people should pay attention to the following points when wearing sunglasses
- It is best to choose lenses that can block ultraviolet rays. Be sure to look at the logo carefully. It does not mean that the higher the price, the stronger protection will be provided. The elderly can choose different sunglasses on different occasions. For example, when fishing, you should choose a polarizer, which can eliminate the strong light from all directions and make the field of vision clearer. When the elderly go to the outskirts to climb mountains, they can choose gray or brown sunglasses, which have better anti-ultraviolet function.
- When crossing the road or going to a shaded place, take off your sunglasses in time, because from a bright place to a dark place, or to a place where people and vehicles are concentrated, the eyes have an adaptation process, which can easily lead to blurred vision, so you should take it off in time. Sunglasses are safer. It is not advisable to wear sunglasses for too long. It is recommended to take off and rest every one or two hours, and gently massage the eye area. Otherwise, symptoms such as headache, irritability, blurred vision, and even decreased vision may occur.
- Ultraviolet rays reach their maximum intensity from 10:00 am to 2:00 pm. At this time, you should minimize going out or go to places that can reflect light, such as waterside and sandy areas, which will increase the chance of light being projected on the eyes.
Last few words
Finally, I remind everyone that it is wrong for some elderly people to go to the optical store or the street to buy a pair of sunglasses. It is recommended that you must go to regular professional channels to buy.
