Direct sunlight is harmful to the eyes, for example, it can cause transient vision loss, corneal damage, lens aging, lid fissures and other injuries.
1. Transient vision loss: If you look directly into the sunlight, it may lead to transient vision loss. After avoiding direct sunlight, you may find that you cannot see the objects in front of you clearly, or even the risk of crashing and falling. For this situation, it is recommended to close the eyes and rest for a while, and to avoid the sunlight, which can make the vision loss alleviated.
2, corneal damage: If you look directly at the sunlight for a long time, or work in the sunlight, but also did not do the corresponding protective measures, may make the corneal cells photochemical damage, so that patients appear eye pain, tearing, photophobia, foreign body sensation and other performance. If the corneal damage is mild, it can be treated with rest and medication. For example, oxyfloxacin or tobramycin can be used, and corneal nutrients such as calf blood deprotein extract ophthalmic gel can promote cellular energy metabolism, thus improving tissue nutrition. If the symptoms are serious, surgical treatment may be necessary.
3. Lens aging: If you look directly at the sunlight for a long time, the lens will react to aging in advance and even develop cataract. Patients who do not develop cataracts can avoid direct sunlight, but if they do develop cataracts, they can only be treated with surgery.
4. Blepharospasm: The main cause of this disease is the formation of horizontal, triangular or oval, elevated, grayish-yellow bulbar conjunctival nodules at the connection of the angular scleral margin in the blepharospasm area caused by long-term direct sunlight. If there are no obvious symptoms or if it does not affect the appearance, treatment is usually not necessary. If there are symptoms that affect the appearance and if there is recurrent inflammation, treatment with artificial tear drops may be given.
