What happens when you wear your glasses while reading text on your mobile phone? Is it blurry, or is your vision corrected?
Ciliary muscles control the shape of the lens to adjust the eye's focus on different objects.
When looking at a closed object, such as mobile phone, the ciliary muscles contract to increase the curvature of the lens, allowing the eye to focus on close distance, correct?
When looking at a distant object over 1 meter, the ciliary muscles relax to flatten the lens, allowing the eye to focus on distant object, correct?
Currently, my glass's degrees is 200 degrees, so I need to replace a new glass, whenever I use mobile phone, I need to remove my glass for closed object.
For glasses with -3.00 diopters (300 degrees) nearsightedness, optometrist suggests 3 different glasses as shown below
1) 300 degrees for mobile phone
2) 275 degrees for Notebook screen
3) 250 degrees for distant objects over 1 meter
If I select (2) 275 degrees for Notebook screen, which I spend most of time, so ciliary muscles would work less on contracting ciliary muscle on closed object.
For monitoring mobile phone without glass, contracting ciliary muscle for closed object, would it cause any eye strain and other vision problems for long term?
For distant object, I would get a blur image, since ciliary muscle do not able to flat the len enough (relaxing ciliary muscle) for clear distant object, would it cause any eye strain and other vision problems for long term?
Do you have any suggestions?
Thank you very much for any suggestions (^v^)
