Minus 7 is considered to be very poor eyesight. People with this level of vision usually have difficulty seeing things clearly at a distance and may need to wear glasses or corrective lenses. In some cases, the vision may be so poor that even corrective lenses cannot help.
The Effects of Minus 7 Eyesight
People with minus 7 eyesight may have difficulty reading signs, recognizing faces, and seeing far away objects clearly. They may also experience difficulties in judging distances accurately or seeing objects in the dark. Additionally, the person may be at an increased risk of developing serious eye problems, such as glaucoma, cataracts, or retinal detachment.
Treatment Options for Minus 7 Eyesight
Fortunately, there are several treatment options available for people with minus 7 eyesight. The most common treatments include corrective lenses, such as glasses or contacts, and laser eye surgery.
Corrective Lenses
Corrective lenses, such as glasses or contacts, can help people with minus 7 eyesight see more clearly. Depending on the person's specific vision needs, glasses or contacts may be the best option. However, it is important to note that glasses and contacts will not be able to improve the person's vision beyond minus 7.

This procedure is generally safe and effective, but it is important to note that it will not be able to improve the person's vision beyond minus 7.
