Patients with cataracts usually watch television without much effect because cataracts are mainly caused by age or trauma, resulting in clouding of the crystal, which can lead to loss of vision. Watching TV regularly will not aggravate the cataract process and will not affect the prognosis of cataract surgery. In general, even if you have cataract, you can watch TV if your vision allows you to do so, and watching TV will not aggravate your condition. If the cataract has developed to a certain level, the vision will be affected to a greater extent and you may not be able to see clearly on TV, so you should consider surgery at this time. Cataract surgery is relatively mature at present, and the surgery is relatively quick, about 15-20 minutes, and the post-operative effect of vision correction is also good.
