Moderate changes in your vision are normal and can be expected as you age. These may also happen due to a condition called presbyopia in which the eye lenses lose their elasticity. Nevertheless, none of these reasons will cause you to suddenly have blurry vision.

Here are some of the possible causes of sudden vision changes.
Detached Retina
This occurs when the retina tears away from the back of the eye, losing its blood and nerve supply. A detached retina can cause you to see flashing lights and black flecks followed by blurred or absent vision on a certain area.
If you experience these symptoms, make sure to go to an eye care center and get emergency treatment to avoid permanently losing vision in that area.
Eye Strain
Eye strain commonly occurs when you look at and focus on something for an extended period without breaks – for example, when you’re working in front of your computer or using your mobile phone. To prevent eye strain, don’t forget to take a break from looking at digital screens. You can also do eye exercises and, if possible, limit your screen time to a few hours per day.
Eye Infection
Some eye infections may require urgent treatment depending on the severity of the symptoms. Below are some eye infections that commonly occur:
- Conjunctivitis – a bacterial or viral infection affecting the blood vessels in the membrane around the eyeball. Symptoms include blurry vision, pink or red eyes, and eye discharge.
- Orbital cellulitis – a bacterial or fungal infection affecting the eyelids and the eyeball. Symptoms include fever, bulging of the eye and difficulty moving the eye.
- Keratitis – the inflammation or infection of the cornea. Symptoms include redness, tearing, irritation and pain in the eye.
