Here is a good website to read. https://www.healthline.com/nutrition/eye-vitamins. And my best advice to you would be to have this conversation with your own eye doctor who knows your eyes better than anyone. And he or she can then take your concerns and advise you as to what would be the best course of action for you. And certainly, before taking ANY vitamins or supplements, consult and advise your family MD, always.
Not necessarily, vitamin deficiency is rare to cause vision loss especially with our fortified diet in the US. Vitamin formulations like AREDS, help reduce the risk of devoloping macular degeneration but your issue may very well stem from something else altogether. An eye exam with dilation is highly recommended.

Vitamin A is a group of antioxidant compounds that play an important role in vision, bone growth and health of the immune system. In general, there are two types of vitamin A, depending on the type of food source it comes from. Vitamin A from animal-derived foods is called retinal and can be used directly by the body. The other form of Vitamin A is obtained from colorful fruits and vegetables in the form of provitamin A carotenoids which are converted by the body to retinol. Beta-carotene is one of the most effective and prevalent carotenoid.
Good sources of retinol include whole milk, cheese, beef and chicken liver. Good sources of provitamin A carotenoids include carrots, sweet potatoes, cantaloupes, spinach, and kale.
Vitamin A is essential for good vision. When in combination with other antioxidant vitamins, Vitamin A appears to play a role in decreasing the risk of vision loss from macular degeneration. The combination of Vitamin A and lutein may prolong the vision in people with retinitis pigmentosa.
In the Unitied States, Vitamin A deficiency is rare, but it is common among the poor un-developed countries. Vitamin A deficiency also causes damage to the retina, which also contributes to night blindness.
In most cases, it's best to obtain vitamins and minerals from a healthy, balanced diet. The recommended daily value for Vitamin A is 5,000 IU. Make sure you clear any supplements with your doctor prior to taking them.
Vitamin A and the antioxidants of C, E, and K will help retina health, but in terms of slowing down your prescription, they won't help. There are options such as myopia management and ortho keratology that can slow down your annual prescription changes.
There are a number of supplements you can take for the eyes. I would recommend that you see an eye doctor who also is an ocular nutritionist. You can go to the Ocular Wellness and Nutrition Society website to find a specialist near you.
Vitamin A supplements may not improve your vision or visual acuity, but some people have reported improved contrast with some macular supplements. Vitamin A is necessary for retinal metabolism, but proper amounts should be followed.

If it's getting worse quicker than usual, then maybe you need to go see an ophthalmologist.
Studies show that Vitamin A can help protect your visual health, but not as well as vitamins that are called carotinoids. These vitamins help protect the retina's health. As for vision getting worse even though you have new glasses it may not prevent changes in your nearsightedness. Many times occupations that rely on heavy use of computers can cause your glasses prescription to continually get worse, which is a function of over focusing by heavy use of a computer, or concentrated near use. To help with this issue many times a specific computer glasses prescription will help more, by lessening the amount of focusing you need to do and by blocking excessive blue light from the computer or electronic device.
Lutein and Zeaxanthin (Vitamin A) improve photosensitivity, glare sensitivity, contrast sensitivity, and night vision when taken long term. Vitamins A through E are important for the eye, as well as drinking plenty of water.
Vitamin A or any antioxidants are generally good.
