Your eyesight has changed a bit with a measurement of -0.25D. This might make your vision less clear and give you sore eyes or a headache. If you spend lots of time looking at screens (like phones), these symptoms could get worse than they already are. To protect your sight, attempt to keep screen use down to 2 hours everyday maximum and take breaks every 20 minutes or so where you focus on something in the distance. You should still wear your glasses as directed by the optician as well. 

The retina is a thin film of tissue making the inner surface of your eye that transmits the images outside to your brain. Problems with the retina can lead to serious vision issues. Signs of the problem with the retina you might get are blurred vision, flashes of light that come out of nowhere, and the perception of something that is not there in your field of vision. Causes can range from aging to serious conditions like diabetes. In the case of treatment, the restoration of vision is usually done by a surgical operation on the damaged retina.

You might be having allergic reactions triggered by your exercise. When you do certain workouts at the gym, like lifting weights or floor exercises, your eye swells up. This could be due to allergens at the gym or materials from the equipment. It's good that outdoor activities don't cause this problem. To prevent the symptoms, try wearing protective eyewear (goggles) at the gym or using antihistamine eye drops before you work out. It's a good idea to consult with an allergist for a complete evaluation and management plan.
