Will the degree increase at the age of 18

The degree of myopia may continue to increase after the age of 18, mainly related to eye habits, genetic factors, environmental stimuli, eye diseases, and growth and development. The control methods include scientific correction, behavioral intervention, regular check ups, nutritional supplementation, and medical means.

1. Eye habits: Long term close eye use can cause sustained tension in the ciliary muscle, accelerating axial growth. It is recommended to gaze for 5 minutes every 40 minutes, maintain a reading distance of at least 30cm, and avoid using electronic screens in dark environments. Using anti blue light glasses can reduce screen light stimulation.

2. Genetic factors: The genetic probability of high myopia in both parents is over 50%. This group of people needs to undergo mydriatic refraction every six months, and choosing corneal reshaping lenses has better control effects than frame glasses. Genetic testing can assess developmental risks.

3. Environmental stimuli: Ultraviolet radiation and dry environments can exacerbate eye fatigue. Outdoor activities require wearing UV400 sunglasses and maintaining indoor humidity between 40% -60%. Alternating distance vision movements such as table tennis can enhance the ability to regulate.

4. Eye lesions: Diseases such as keratoconus or glaucoma can cause abnormal changes in degree. If symptoms such as visual distortion and iridescence occur, seek medical attention immediately. Corneal topography and intraocular pressure examination can detect lesions early.

5. Developmental factors: Eye axis growth can last until the age of 25 in some populations. It is recommended to have quarterly check ups and choose multifocal lenses for the age group of 18-22. Low concentration atropine eye drops combined with visual training can effectively delay progression.

Maintaining 2 hours of outdoor activity every day, consuming dark green vegetables rich in lutein, using hot compress eye masks to relieve fatigue, and establishing a visual health record to track trends can significantly reduce the risk of degree growth in adulthood.
