Water filtration
https://a.co/d/4c6qJzV
Cost 33$
replacement filters
15-25$
Per year 45-85
2 cases of Kroger water x2 month
3-4$ per case
156$ per year
Filtration system needs replacing every 3-6 months. I based it off; Top Maintenance and Quality Drinking water.
This also reduces trash and plastic waste
Cons
May require buying a set of stainless steel cups for sorting and avoiding taste/texture mixing due to my sensory sensitivities
Now secondly
RGB Bulbs

28$ 4 pack
I need 4 bulbs
Power Consumption at 10% Brightness:
- Typical power usage at 10% brightness: Approximately 1 watt per bulb (for simplicity).
2. For one bulb running 24/7 at 1 watt:
- Daily consumption: 1 watt × 24 hours = 24 watt-hours or 0.024 kWh.
- Daily cost: 0.024 kWh × $0.12 = $0.0029 (about 0.3 cents).
- Annual cost: $0.0029 × 365 = $1.06.
3. For one bulb running 3 hours per day at 1 watt:
- Daily consumption: 1 watt × 3 hours = 3 watt-hours or 0.003 kWh.
- Daily cost: 0.003 kWh × $0.12 = $0.00036 (about 0.04 cents).
- Annual cost: $0.00036 × 365 = $0.13.
4. For four bulbs at 10% brightness:
- All bulbs running 24/7: $1.06 per bulb × 4 bulbs = $4.24 annually.
- All bulbs running 3 hours per day: $0.13 per bulb × 4 bulbs = $0.52 annually.
If all four bulbs are dimmed to 10% and used as described, the total annual cost would be:
- Four bulbs running 24/7: $4.24
- Four bulbs running 3 hours daily: $0.52
- Total annual cost: $4.76
Edit: I’m getting all of this myself
You're conflating your personal experience as being generally common. You may have benefit from these, but they are not a back to school necessity or even consideration for "every parent." For the vast majority of people these are unnecessary.
While yes not everyone has these. What it’s important to consider is if a kid has these issues and even if they don’t it may be best to give them the technology incase they ever had eye problems or otherwise. Ive started learning the best way to enhance development and comfort. I guess in my experience I like being cautious and covering every aspect of an issue.
