The strange gray spot in the field of vision could be a floater, which is a small, dark spot or shadow that moves around in the field of vision. Floaters are caused by tiny bits of debris in the vitreous, the gel-like substance that fills the inside of the eye. They are usually harmless, but if you suddenly see a lot of new floaters, or if you also see flashes of light, it could be a sign of a retinal tear or detachment, and you should see an eye doctor immediately. **

Shopping can still be fun without money by simply browsing and trying on different items, exploring new trends, and getting inspiration for future purchases. It can also be enjoyable to create wish lists or window shop without the pressure of making a purchase. Additionally, participating in free events or activities at shopping centers, such as live music or art exhibits, can also make the experience enjoyable without spending money. Ultimately, the enjoyment of shopping can come from the experience and the social aspect, rather than the act of purchasing items. **

Online shopping offers convenience and the ability to compare prices and products from the comfort of your own home. However, traditional shopping allows for a more tactile and sensory experience, as well as the immediate gratification of taking home your purchases. Both have their advantages, and the choice ultimately depends on personal preferences and the specific needs of the shopper. **

A bright spot in the field of vision can be caused by a condition called a retinal migraine, which is a type of migraine that affects the vision in one eye. This can result in the perception of bright, shimmering lights or spots in the visual field. Another potential cause could be a retinal tear or detachment, which can lead to the perception of flashes of light or bright spots in the vision. It is important to seek medical attention if you experience these symptoms, as they could indicate a serious underlying issue with the eye. **

A black spot in the field of vision after looking at a screen could be a symptom of digital eye strain or computer vision syndrome. This occurs when the eyes are overworked from staring at a screen for long periods of time, leading to symptoms such as blurry vision, dry eyes, and headaches. It is important to take regular breaks from screen time, adjust the screen's brightness and contrast, and ensure proper lighting in the room to reduce the risk of developing digital eye strain. If the black spot persists or is accompanied by other concerning symptoms, it is important to seek medical attention from an eye care professional. **

Online shopping offers convenience and the ability to compare prices and products from the comfort of your own home. It also allows for easy access to customer reviews and a wider selection of items. On the other hand, in-store shopping provides the opportunity to physically see and touch the products before making a purchase, as well as the immediate gratification of taking the item home with you. Ultimately, the choice between online and in-store shopping depends on personal preferences and the specific needs of the shopper. **
