Before going to bed every night, turn off the lights, stuff the quilt, pick up the phone , “Bedtime Ritual” has.
Many people like to check their mobile phones before going to bed. The dim environment makes people feel drowsy. But what they don’t know is that this habit is actually very harmful.

Why does turning off the light and looking at the mobile phone induce glaucoma? Can glaucoma eventually lead to blindness? Let’s explore it below.
What is glaucoma?
Glaucoma is a chronic and progressive ophthalmology characterized by pathological elevation of intraocular pressure (normal intraocular pressure is 10-21 mmhg), causing visual field defect, optic disc depression, and optic atrophy. disease.
Glaucoma, cataract and age-related macular degeneration are the three major blind eye diseases in ophthalmology.

There are many types of glaucoma, the common ones can be divided into primary closed eye Angle glaucoma, primary open angle glaucoma, secondary glaucoma, congenital glaucoma, etc.
The onset of glaucoma is mostly insidious, the visual field is progressively reduced, and the optic nerve atrophy causes blindness. (With the intermittent and continuous increase of intraocular pressure, visual field damage, tubular visual field, and finally blindness occurs gradually.)
Glaucoma patients are mostly female, The ratio of male to female can reach 1:4, and the blindness rate of glaucoma is 10%, which is relatively high.

In acute glaucoma, it can be manifested as a sharp increase in intraocular pressure, Patients present with symptoms such as eye pain, eye swelling, redness, decreased vision, headache, nausea and vomiting, and visual acuity.
Does turning off the lights and playing with mobile phones induce glaucoma?
There is a certain probability that glaucoma may be induced by turning off the lights and playing with mobile phones.
However, turning off the lights and playing with your phone is not the cause of glaucoma, it’s just a predisposing factor for glaucoma.

When the light is turned off, the pupil in the eye dilates, which to a certain extent causes The aqueous humor circulation disorder in the anterior and posterior chambers of the eye can cause fluctuations in intraocular pressure and even increase in intraocular pressure. If encountering patients with abnormal anterior segment anatomy (shallow anterior chamber, narrow angle of the chamber), it will cause pupillary block and induce acute glaucoma. attack.
Can I be blind with glaucoma?
Glaucoma, if the intraocular pressure is not properly controlled, slowly causes optic nerve atrophy, resulting in visual field defects, which can lead to blindness within a few years.
Glaucoma requires long-term follow-up. Once suffering from glaucoma, it is necessary to visit an ophthalmologist regularly, and symptomatic treatment is required according to the type, symptoms, intraocular pressure, and visual field of glaucoma.

Currently the treatment of glaucoma is mainly divided into drugs and surgery:
Drugs include ocular hypotensive eye drops and oral or systemic intravenous infusions, which can be treated with one drug or in combination with multiple drugs;
Surgery includes laser, trabeculectomy, and drainage valve implantation.
How can glaucoma be prevented?
Glaucoma is the “thief” of vision, so it is extremely important to prevent glaucoma:
1. Those with family history of glaucoma need regular ophthalmology Check intraocular pressure, slit lamp examination, and visual field examination, and follow up regularly.
2. Age 40 years old, patients with high myopia, hyperopia and diabetes need regular ophthalmic follow-up and blood sugar control.
3. Maintain emotional stability, be less angry and less angry, especially for female patients, keep a good mood.

4, As little as possible in dim light Work and study in an environment.
5. If the elderly have obvious cataract, cataract surgery should be performed as soon as possible to avoid secondary glaucoma.
6. Don’t use hormonal drugs frequently, especially hormonal eye drops, long-term use can cause hormonal glaucoma.
