| I’ve had astigmatism my whole life, and worn glasses or contacts since age 4. 1. Wear your glasses! Even if you think you can see OK for a while without them. 2. The floaters and light-sensitivity should be checked by a medical professional (although apparently many people do get floaters with age). I’ve never had any problems with either. Note the difference between an opthalmologist (a doctor who diagnoses and treats eye conditionss), an optometrist (who measures you for corrective lenses) and an optician (who makes and supplies the lenses). Here in Australia, good optometrists will check you for some common eye conditions as part of our universal health system, but that isn’t necessarily the case elsewhere, and it’s only common conditions. 3. Regardless of light or dark themes, a good quality, bright, high-contrast and high-resolution screen with good quality fonts. (Up until Apple’s font patents expired quite recently, that last meant a Mac.) Example: iMac Retina 5K. I guess their new Studio Display which replaced it. 4. Light themes where possible. Black text on white, not grey on white, not grey on mid-grey or anything else dreamt up by some amateur designer with their screen brightness racked up too high. No amateur-designed fonts. I use 16 point Courier in black on white in Xcode, with syntax highlighting turned off completely. I do use some software whose only workable themes are dark (typical for photographic software) and then use a separate dark desktop and set the text to crisp white. 5. Room lighting should not be too dark. |
