The human lens has a natural ability to change its shape or accommodate in order to focus on objects up close. In our 20's and 30's, we are able to accommodate without difficulty. Presbyopia occurs when the lens no longer has the ability to change shape, thereby requiring the use of reading glasses to compensate.
| Symptoms |
- loss of ability to read or focus on the computer
- preserved distance vision
- eye strain or headache after prolonged concentration up close
- difficulty changing focus from distance to near
|
| Diagnosis |
- comprehensive eye exam with attention to vision at distance and near will help diagnose presbyopia; exact prescription needed to correct vision for near will also be calculated
|
| Treatment |
- over the counter reading glasses are adequate for those who still have good vision without correction for distance; otherwise bifocal correction is needed and can be achieved through glasses or contacts
